Risk Factors Associated with Angiographic Severity of Coronary Artery Disease Based on Serum Uric Acid: A Study in a Tertiary Care Hospital, Chattogram, Bangladesh

Background: Coronary Artery Disease (CAD) is a leading cause of death worldwide, identifying risk factors and severity is crucial for management and prevention. Serum Uric Acid (SUA) has been proposed as a potential marker for the severity of CAD. Elevated SUA levels are associated with endothelial dysfunction, oxidative stress, and inflammation, all of which contribute to the development and progression of atherosclerosis. This study aims to determine the association of risk factors with the severity of CAD using SUA levels. Materials and methods: This was a cross-sectional observational study conducted in the Department of Cardiology at CMCH in Chattogram over one year from October 2020 to September 2021. After case selection demographic data were collected and transthoracic echocardiography was performed on study patients. Results: The study analyzed the association between SUA level and CAD severity in 130 patients undergoing coronary angiography. The mean SUA level was 5.06 mg/dl and was significantly associated with the presence of CAD, number of vessel involvement and severity of CAD assessed by the Gensini score. The mean SUA level in cases with CAD was significantly higher (5.26 ± 1.32 mg/dl) than in cases without CAD (4.22 ± 1.03 mg/dl). Conclusion: This study concluded that demographic variables and risk factors are associated with the severity of CAD. The severity of CAD was higher in elderly and male patients. The study suggests that when assessing the risk in a CAD patient, hyperuricemia should be considered. IAHS Medical Journal Volume 6(2) December 2023; 48-52

Medication management and electrocardiogram screening in children with attention deficit hyperactivity disorder.

To quantify the proportion of referrals sent to Crumlin Cardiology Department for cardiac screening prior to commencement or modifying attention deficit hyperactivity disorder medication and assess the number detected with a clinically significant abnormality. A prospective audit was performed over a 6-month period, from November 2021 to April 2022 inclusive. Referrals sent via outpatient department triage letters, electrocardiogram dept. email, and walk-in electrocardiogram service were screened for those pertaining to commencing or modifying medication for children with attention deficit hyperactivity disorder. Each referral was coded against National Institute for Health and Care Excellence guidelines to determine the degree of clinical details given. Reported abnormalities, recommended management, and correspondence were recorded. Ninety-one referrals were received during the 6-month audit period. More than half lacked a clinical indication for referral (53/91, 58.2%), with fewer than one third (26/91, 28.5%) meeting National Institute for Health and Care Excellence criteria for referral for cardiology. Eighty (80/91) referrals had clinical outcomes available for review (missing outpatient department information and age outside of service range accounted for eleven referrals with unavailable clinical outcomes). Of the eighty clinically reviewed referrals, seventy-two (72/80, 90%) were reported as normal with no cardiology follow up required. Eight referrals (8/80, 10%) were reviewed in the Cardiology Outpatient Department prior to commencement or modifying attention deficit hyperactivity disorder medication. Of these, only one (1/80 1%) had a clinically significant abnormality which was a potential contraindication to attention deficit hyperactivity disorder medication use, and this referral was appropriate as per National Institute for Health and Care Excellence guidelines. Routine screening prior to attention deficit hyperactivity disorder medication prescription in the absence of clinical indications (as per National Institute for Health and Care Excellence) contributed to delays in medication initiation among young people with attention deficit hyperactivity disorder. Unnecessary referrals have resource implications for cardiology clinical team. Improved adherence to National Institute for Health and Care Excellence guidelines would provide benefits for patients and clinicians.

Effectiveness of Hospital Fit on Physical Activity in Hospitalized Patients: A Stepped-Wedge Cluster-Randomized Trial and Process Evaluation.

This study investigates the effectiveness of using Hospital Fit as part of usual care physiotherapy on the physical activity (PA) behavior of hospitalized patients compared to patients who received physiotherapy before implementation of Hospital Fit. In addition, a process evaluation is conducted. A prospective, multi-center, mixed-methods stepped wedge cluster randomized trial was performed at the cardiology and medical oncology departments of two Dutch university medical centers. Patients were included in the non-intervention or intervention phase. During the non-intervention phase, patients received usual care physiotherapy. During the intervention phase, Hospital Fit was additionally used. Mean time spent walking, standing, lying/sitting per day and the number of postural transitions from lying/sitting to standing/walking positions were measured using an accelerometer and analyzed using linear mixed models. A process evaluation was performed using questionnaires and semi-structured interviews with patients and focus-group interviews with healthcare professionals. A total of 77 patients were included, and data from 63 patients were used for data analysis. During the intervention phase, the average time spent walking per day was 20 min (95% confidence interval: -2 to 41 min) higher than during the non-intervention phase (p = 0.075). No significant differences were found for mean time spent standing per day, mean time spent lying/sitting per day, or the number of postural transitions per day either. During the intervention phase, 87% of patients used Hospital Fit at least once, with a median daily use of 2.5 to 4.0 times. Patients and healthcare professionals believed that Hospital Fit improved patients' PA behavior and recovery. Insufficient digital skills and technical issues were described as challenges. Although patients and healthcare professionals described Hospital Fit as an added value, no statistically significant effects were found.

Identifying Palliative Care Needs in Patients With Heart Failure Using Patient Reported Outcomes

ContextHeart failure (HF) is considered a multifaceted and life-threatening syndrome characterized by high symptom-burden and significant mortality. ObjectivesTo describe the symptom-burden in patients with HF and identify their palliative care needs. In this respect, symptom burden related to sex, age and classification of HF using New York Heart Association Functional Classification (NYHA) were analyzed. MethodsA cross-sectional questionnaire survey included adult HF patients according to NYHA II, III, and IV. Palliative care needs were assessed using validated patient reported outcomes measures; SF-36v1, HeartQoL, EORTC- QLQ-C15-PAL, MFI-20 and HADS. Patients were recruited from the Department of Cardiology, North Zealand Hospital, Denmark. ResultsIn total, 314 patients (79%) completed the questionnaire (233 men). Mean age = 74 years (range 35–94 years). In all, 42% had NYHA III or IV and 53% self-rated their health to be fair or poor. In all, 19% NYHA II and 67% NYHA III/IV patients had ≥4 severe palliative symptoms according to EORTC-QLQ-C15-PAL. In addition, NYHA III/IV had a mean of 8.9 symptoms and a mean of 5.4 severe symptoms. Women, older patients, and those with NYHA III/IV had worse outcomes regarding health-related quality of life, functional capacity, and symptom burden. ConclusionsPatients with HF have a high prevalence of symptoms and, thus, potential palliative care needs. Predominantly, women, older patients, and those with higher severity of disease have the highest symptom burden. PROMs can help cardiologists address the palliative care needs and systematic assessment may be a prerequisite to integrate symptom-modifying and palliative care interventions.

Correlation Between the Neutrophil-to-Lymphocyte Ratio and the Severity of Coronary Artery Disease in Patients With Myocardial Infarction.

Background Coronary artery disease (CAD) is one of the major causes of death all over the world. Its severity evaluation through the Gensini scoring system is quite a complex process as these score systems require complex investigations and cardiologists. Therefore, this study aimed to determine the predictive capacity of neutrophil-to-lymphocyte ratio (NLR) for the severity of CAD in patients with myocardial infarction. Methods This cross-sectional study was performed on 208patients with acute myocardial infarction whose coronary angiography was performed in the Department of Cardiology of Benazir Bhutto Hospital (BBH), Rawalpindi, Pakistan during the period of one year from January 2022 to March 2023. The enrollment of patients was made through purposive sampling and established inclusion and exclusion criteria. Ethical approval and informed consent were acquired before the data collection. Data was collected through a self-structured form. Vessel score and Gensini score were applied for the assessment of the severity of CAD. Patients were divided into two groups based on the Gensini score system. Data analysis was carried out in the Statistical Package for the Social Sciences (SPSS) version 25 (Released 2017; IBM Corp., Armonk, New York, United States). Both descriptive and inferential statistics were used to compare the study variables between the patients with non-severe CAD and patients with severe CAD. Pearson's correlation was used to determine the correlation between the NLR and the severity of CAD. A linear regression model was applied to evaluate the predictive capacity of the NLR for the severity of CAD. A p-value less than 0.05 was set as statistically significant. Results Out of 208 patients, 128 (61.53%) patients had non-severe CAD while 80 (38.47%) patients had severe CAD. Significant differences were observed in the Gensini mean scores, NLR values, and in the frequencies of hypertension, diabetes mellitus, dyslipidemia, and history of smoking, with p≤0.05 for all these variables, between the non-severe CAD group and severe CAD group. NLR was significantly correlated with the severity of CAD (p-value=0.001). Pearson's correlation coefficient was 0.71 for NLR with the Gensini scores. The simple linear regression model was valid (the p-value of the F test was <0.000), with beta coefficients of 2.60 (p=0.002) for NLR. The R2 value was 0.80 (80%). Conclusions In the current study, a significant percentage of patients had severe CAD. Furthermore, a positive and significant association was noted between the NLR with the severity of CAD. This present study suggests that NLR is a reliable predictor of CAD severity; therefore, it could be used for risk stratification of cardiac patients with CAD.

An unexpected bronchoscopic finding possibly induced by extracorporeal membrane oxygenation: A case report of bronchial Dieulafoy disease.

Bronchial Dieulafoy disease (BDD), a rarely reported disease, comes from dilated or abnormal arteries under the bronchial mucosa. Patients with BDD are generally asymptomatic so this disease is frequently misdiagnosed. However, the submucosal arteries may dilate and rupture for various reasons, leading to recurrent respiratory tract bleeding and potentially life-threatening conditions. With the change of reversible factors such as intravascular pressure, the arteries may return to normal, allowing patients to recover to an asymptomatic state. This phenomenon has not been mentioned and concerned in previous studies, but it may have important implications for our correct understanding of this disease. A 44-year-old female was admitted to intensive care unit with recurrent malignant arrhythmias. With the assistance of VA-extracorporeal membrane oxygenation (ECMO), both her vital signs and internal environment were all gradually stabilized. However, she had been experiencing recurrent respiratory tract bleeding. While removing the bloody secretion with a fiber bronchoscopy, a congested protruding granule on the wall of the patient's left principal bronchus was found. The patient was diagnosed with BDD and the granule was thought to be an abnormal artery of BDD. For the patient's condition, we did not implement any targeted interventions with the abnormal artery. After the weaning of VA-ECMO, the patient's granule could not be found and the bleeding had also disappeared. She gradually weaned off the mechanical ventilation and was transferred to the Department of Cardiology. Then the patient was discharged after her condition stabilized. In more than half a year, the patient is in a normal physical condition. The appearance and disappearance of abnormal artery is an interesting phenomena of BDD. The change of intravascular pressure due to various causes such as VA-ECMO may be the primary factor of it.

Prognostic impact of CONUT score in older patients with chronic heart failure

BackgroundMalnutrition is common in older patients with chronic heart failure (HF) and often accompanies a deterioration of their condition. The Controlling Nutritional Status (CONUT) score is used as an objective indicator to evaluate nutritional status, but relevant research in this area is limited. This study aimed to report the prevalence, clinical correlates, and outcomes of malnutrition in elder patients hospitalized with chronic HF.MethodsA retrospective analysis was conducted on 165 eligible patients admitted to the Department of Cardiology at Huadong Hospital from January 2021 to December 2022. Patients were categorized based on their CONUT score into three groups: normal nutrition status, mild risk of malnutrition, and moderate to severe risk of malnutrition. The study examined the nutritional status of this population and its relationship with clinical outcomes.ResultsFindings revealed that malnutrition affected 82% of the older patients, with 28% experiencing moderate to severe risk. Poor nutritional scores were significantly associated with prolonged hospital stay, increased in-hospital mortality and all-cause mortality during readmissions within one year (P < 0.05). The multivariable analysis indicated that moderate to severe malnutrition (CONUT score of 5–12) was significantly associated with a heightened risk of prolonged hospitalization (aOR: 9.17, 95%CI: 2.02–41.7).ConclusionsMalnutrition, as determined by the CONUT score, is a common issue among HF patients. Utilizing the CONUT score upon admission can effectively predict the potential for prolonged hospital stays.

Progression, Management, and Outcome of Aortic Valve Stenosis in Systemic Sclerosis: A Case Series.

In systemic sclerosis (SSc), cardiac involvement is frequent, heterogeneous, and related to a poor prognosis. Due to a longer life expectancy, the development of degenerative aortic stenosis (AS) is not uncommon. The aim of this article is to report the characteristics of AS in SSc, analyzing the rate of progression, the management, and the outcome. This is a case series conducted at the Department of Cardiology of Monaldi Hospital, Naples, Italy. From January 2007 to December 2022, we analyzed 234 patients with SSc. Ten/234 patients (4.3%) showed severe AS and were included in the analysis (age 75.5 years [IQR 58-84], nine females). Nine had limited and one diffuse SSc. Two patients were in NHYA/WHO II and eight in NYHA/WHO III. All had degenerative three-leaflet AS. Two patients showed severe AS at the first evaluation, and eight developed severe AS during the follow-up, with a time progression from moderate to severe AS of 3.2 ± 1.1 years (progression rate -0.190 ± 0.012 cm2/year for aortic valve area, 8.6 ± 6.1 mmHg/year for mean aortic gradient, 16 ± 7 mmHg/year for peak aortic gradient, and 0.5 ± 0.3 m/s/year for aortic peak velocity). Seven out of 10 patients underwent transcatheter aortic valve implantation (TAVI), one underwent surgical aortic valve replacement (SAVR), one was left untreated, and one was on a waiting list for TAVI. No major complications after TAVI or SAVR occurred. At a mean follow-up of 5.9 ± 3.9 years, eight patients are alive and two died. Severe AS is a relevant cardiac complication of SSc and must be considered in the screening and during the follow-up. Its rapid progression rate may tentatively be due to autoimmunity, degenerative burden, and chronic inflammation.

Use of ultrasound for vascular access during cardiac catheterisation in children with congenital heart disease: a Swiss multicentre cohort study.

Our study aimed to assess the first-attempt success rate of ultrasound (US) and anatomical landmark (ALM) guidance for vascular cannulation in children with congenital heart disease in Switzerland. A prospective observational multicentre study was conducted from January 2022 to January 2023 in three university hospitals in Switzerland. We included patients with congenital heart disease aged 0 to 18 years who were scheduled for elective cardiac catheterisation. Periprocedural data were collected anonymously. The choice of vessel and guidance technique were at the operator's discretion. 177 arterial and 240 venous cannulations in 253 patients were analysed. The median age and weight were 4.4 years (interquartile range [IQR] 1.2-8.8) and 15 kg (IQR 8-27), respectively. Nearly all operators, 97.5%, were deemed experienced. The femoral artery and femoral vein were the most preferred vessels. US guidance was used in 62% of procedures, predominantly within populations who were younger, smaller and of lower weight.The success rate at the first attempt was notably higher with US guidance for arterial cannulation (US: 80%, ALM: 37%, p <0.001) and venous cannulation (US: 78% vs ALM: 47%, p <0.001). Overall success rates for venous and arterial cannulation were comparable between ultrasound and anatomical landmark guidance. A total of 45 complications (10.5%) occurred, with immediate uncomplicated haematoma being the most frequent. US guidance is preferred for the localisation and cannulation of vessels during cardiac catheterisation within paediatric cardiology departments in Switzerland. Given its high success rate for first-attempt cannulation, US warrants additional research to evaluate its potential in reducing complications.

Association of HBA1C level with extent of Acute Myocardial Infarction and Short Term Mortality

ABSTRACT Objectives: To determine the prognostic value of HBA1C level with extent of acute Myocardial Infarction (MI) and short-term mortality in patients without known Diabetes. MATERIAL AND METHODS The prospective cohort, department of Cardiology at Liaquat University Hospital Hyderabad during the period of one year from February 2020 January 2021. All the patients aged 20-75 years, both genders with acute MI (STEMI and NSTEMI) were included. All the patients diagnosed for MI according to ECG and serum cardiac biomarkers such as Troponin-T and Troponin-I. Blood sample were taken from all the cases for assessment of HbA1c level. Echocardiography was done and categorized according to the left ventricle ejection fraction. Short term mortality was assessed in all patients. All the data was recorded in the proforma for the purpose of analysis. After collection of data the analysis was conducted by using SPSS version 22.0. Results: Total 377 patients of acute MI were studied; their mean age was 50.42+11.71 years. Out of all study subjects’ males were in majority 83.0% and females were 17.0%. Out of all 59.4% had HbA1c level &lt;5.5 and 40.6% had HbA1c was &lt;6.5. Most of the study subjects 62.9% had left ventricular ejection fraction was &lt;40%. Majority of the cases 77.7% had STEMI and NSTEMI was seen in 22.3% of the cases. Overall short-term mortality (30 days) was found 14.3%. In this study short term mortality (30 days) was statistically significant according to the gender, HbA1c, left ventricular ejection fraction and types of the MI, P-&lt;0.05). Conclusion: As pers study conclusion overall short-term mortality (30 days) was 14.3%. Higher HbA1c was observed to be a potential indicator for short term mortality among patients of acute coronary syndrome (ACS) and a predictor for short-term mortality in ACS patients without known DM and without DM Key words: Acute MI, 30 days mortality, Hba1c

Relationship Between Modified Systemic Immune- inflammatory Index and Contrast-Induced Nephropathy in Patients With ST-Segment Elevation Myocardial Infarction

Objective: Developing contrast induced nephropathy after primary PCI in patients with ST segment elevation myocardial infarction is a risky condition in terms of mortality and morbidity. Various studies have shown that the systemic inflammatory index predicts (SII) the development of CIN. Mean platelet volume (MPV) is an important indicator known to be associated with the platelet function and activation. Therefore, we revised SII and named it modified SII (mSII) by using NLR multiply MPV. Materials and Methods: This study includes patients who underwent pPCI due to STEMI in our cardiology department between February 2015 and February 2021. Modified SII was obtained by using MPV instead of platelet in the formula (mSII= NLR x MPV). Patients who underwent pPCI with STEMI were divided into two groups, those with CIN and those without CIN, and compared. Results: In the logistic regression analysis, it was observed that the mSII, NLR, GFR and contrast medium amount was independent predictor of CIN. The optimal threshold mSII for predicting CIN was &gt;42.5, with a 78.1% sensitivity and 52.3% specificity ([AUC]: 0.639, 95%CI: 0.602- 0.674, p&lt; 0.001). Pairwise comparison of ROC curves, it was observed that the predictive value of mSII for the development of CIN was better than NLR. (z-test = 3.144, P = 0.001) Conclusion: We think that mSII, which we have shown to be superior to SII in predicting the development of CIN and is very easy to calculate, is a parameter that can be considered in predicting the development of CIN after pPCI in STEMI patients.

Prescribing Errors in an Ambulatory Care Setting: Mitigating Risks in Outpatient Medication Orders, Cross-Sectional Review

ABSTRACT Introduction Prescribing errors (PEs) are the most common type of medication error, which may occur by prescribing the wrong medication, improper dose, dosage, and/or even prescribing a drug to the wrong patient. The present study aims to compile PEs that were generated in an ambulatory care setting at a tertiary-care hospital in Saudi Arabia. Methods A retrospective cross-sectional review was conducted for all reported PEs in ambulatory care clinics for 3 years. The potential hazardous outcomes of these PEs were classified according to the medication error index. Results A total of 897 records containing 1199 PEs were retrieved. More than a third of prescribers had frequently committed PEs—ranging from 2 to 39 times. The most encountered errors were prescribing incorrect doses, medication duplication, incorrect dosing frequency, and inappropriate duration (34.5%, 14.1%, 11.6%, and 9.8%, respectively). The most frequent mistakes were when prescribing antibiotics (22.9%) and drugs for cardiovascular conditions (18.5%). Most errors were of mild to moderate severity, mostly type-B near-miss errors and did not reach patients. Only two prescription events (0.17%) had severe consequences that required intervention to avoid any subsequent harm or damage. Conclusion The current investigation has revealed a substantial percentage of PEs, mostly in internal medicine and cardiology departments. Although PEs are undoubtedly not easy to avoid, monitoring and recognizing these inaccuracies is pivotal to preventing potential harm and promoting patient safety.

Proenkephalin A 119-159 (penKid) and mortality in stable patients at high cardiovascular risk

ABSTRACT Background Proenkephalin A 119–159 (penKid) is a novel blood biomarker for real-time assessment of kidney function and was found to be independently associated with worsening kidney function and mortality. A novel penKid-based estimated glomerular filtration rate equation (eGFRPENK-Crea), outperforms current creatinine-based eGFR equations in predicting iohexol or iothalamate plasma clearance-based measured GFR. In this study, we aimed to evaluate the predictive value of penKid and eGFRPENK-Crea for all-cause mortality in stable patients at high cardiovascular risk. Methods Circulating penKid levels were assessed in 615 stable patients hospitalized at the Department of Cardiology at University Hospital Aachen, Germany. The endpoint was all-cause mortality; follow up was 3 years. Results penKid levels were higher in 46 non-survivors [58.8 (IQR 47.5–85.0) pmol/l] compared to 569 survivors [43.8 (IQR 34.0–58.0) pmol/l; P &amp;lt; .0001]. Univariable Cox regression analyses found penKid and eGFRPENK-Crea to be associated with all-cause mortality (C index 0.703, χ2 33.27, P &amp;lt; .00001; C index 0.716, χ2 36.51, P &amp;lt; .00001). This association remained significant after adjustment for significant baseline parameters including age, smoking, chronic heart failure, use of diuretics, leucocytes, body mass index, sex, and creatinine (C index 0.799, χ2 72.06, P &amp;lt; .00001). Importantly, penKid provided significant added value on top of eGFRCKD-EPI 2021 (eGFRCKD-EPI 2021: C index 0.716, χ2 34.21; eGFRCKD-EPI 2021 + penKid: C index 0.727, χ2: 40.02; Delta χ2 5.81; all P &amp;lt; .00001) for all-cause mortality prediction in our cohort. Conclusions penKid levels and eGFRPENK-Crea is associated with all-cause mortality within a 3-year follow-up period and the addition of penKid on top of eGFRCKD-EPI 2021 provided significant added value in mortality prediction.

Cardiologists' perspective on termination of pacemaker therapy-an anonymous survey among cardiologists in Germany.

The patient's right to refuse pacemaker therapy is mentioned in the relevant European consensus statement but additional information is only available on deactivation of implantable cardioverter deactivator and not on other cardiac implantable electronic devices such as pacemakers. Therefore, we were interested in opinions, concerns and attitudes of cardiologists, who are the primary contact persons for such requests, since the number of patients asking for withdrawal of pacemaker therapy is likely to increase leaving cardiologists and healthcare professionals with a difficult medical but also ethical problem. An anonymous questionnaire was sent to all German cardiology departments (N = 288). 48% of cardiology departments responded by sending back 247 completed questionnaires. Most participating cardiologists were experienced when considering the duration of their professional activity. Almost all of the respondents regularly perform check-ups of pacemakers. The majority of cardiologists answering our questionnaire were prepared to deactivate a pacemaker upon patients' request, and have done so. In pacemaker dependency, however, the willingness to withdraw decreases, even if death is imminent, for fear of causing distressing symptoms, sense of being responsible for patients possible immediate death, or fear of legal consequences. The survey could clearly show that uncertainties remain among cardiologists dealing with a patient's wish for withdrawal, especially in cases of pacemaker dependency. We suggest that official statements of cardiologic societies in Europe are issued to clarify ethical, legal and practical aspects of pacemaker withdrawal.

Frequency &amp; Predictors of Depression in Patients of Chronic Heart Failure with Reduced Ejection Fraction (HFrEF)

Background: Clinically significant depression is estimated to occur in a significant portion of chronic heart failure (CHF) patients and increases sharply with increase in heart failure severity. However, the frequency and predictors of depression in this group of patients are underreported. This study was designed to assess frequency &amp; predictors of depression in patients of chronic heart failure with reduced ejection fraction (HFrEF). Methods: This cross-sectional analytical study was performed in the department of Cardiology, Dhaka Medical College Hospital, Dhaka, during the period from October’2018 to Septemeber’2019. One hundred and fifty-two CHF patients with reduced ejection fraction (&lt;40%) either admitted in the department of Cardiology or attended Cardiology OPD, Dhaka Medical College Hospital (DMCH), Dhaka who fulfilled the selection criteria were included into the study. A translated and validated Patient Health Questionnaire (PHQ-9) in Bengali was used to assess depression level in CHF patients in this study. Informed written consent was taken from each patient. Approval for the study was taken from Ethical Review Committee (ERC) of Dhaka Medical College before commencement of the study. After compiling data from all participants, statistical analyses were performed using the Statistical Package for Social Science (SPSS), version 22.0 for windows. Results: Mean age of the patients was 58.68±9.40 years, ranging from 36 to 75 years. Male predominance was noted (72% vs 28%). Overall, frequency of depression was 56%. Among the depressed patients (n=85), majority (40%) had minimal depression while 27%, 19% and 14% had mild, moderate and severe depression. respectively. Among the different risk factors, DM and sedentary lifestyle were significantly associated with depression (p&lt;0.05). Age &gt;65 years, sedentary lifestyle, and H/O past MI were independently associated with depression among chronic HErEF patients. Widowed patients, diabetes, hospital readmission in last 2 months before study inclusion and NYHA class III/IV were also significantly associated with depression among patients with chronic HFrEF (p&lt;0.05). Conclusion: More than half of the patients with chronic HFrEF had concurrent depression of varied severity. Proper care of depression along with HF may improve the survival and quality of life of these patients. Bangladesh Heart Journal 2024; 39(2): 74–84

Frequency and Pattern of Anomalous Origin of Coronary Artery in Bangladeshi Population: Coronary Angiogram Based Single Center Study

Background: Anomalous origin of coronary artery (AOCA) has been traditionally described by coronary angiography or autopsy. However the actual prevalence of such abnormalities is unknown in general Bangladeshi population. Beside conventional coronary angiogram(CAG), CT CAG and Multi-detector computed tomography (MDCT) offers higher possibility to visualize AOCA non-invasively. The purpose of this study was to report the prevalence AOCA in Bangladeshi population by using conventional CAG. Methodology: This was a single center, cross sectional, observational study, done in department of Cardiology, BSMMU over 1 year period. Sample size was 1167. Samples were taken following inclusion and exclusion criteria. Descriptive statistical analysis was done by using SPSS v29.0 Results: 1.3% population had AOCA. Commonest (0.6%) was ‘absent Left main (LM) with separate origin of Left Anterior Descending (LAD) and Left Circumflex (LCX) artery. Second commonest (0.45%) was ‘Right Coronary Artery (RCA) arising from left sinus’. 0.17% had RCA highup origin, and 0.08% had RCA origin from posterior sinus. Discussion: Among AOCA, RCA origin from left sinus, is potentially dangerious, due to high risk of sudden cardiac death (SCD) and surgical complications. Other varities of AOCA are mostly benign, but it may cause difficulties in cannulation during coronary angiography and coronary artery bypass surgery. Conclusion: Although coronary artery anomalies are rare, they may cause difficulties during coronary interventions or cardiac surgery and may occasionally result in sudden cardiac death. So, optimum precaution to findout the AOCA is needed during conventional CAG, and if suspicion, CT CAG and MDCT should also be used. (Bangladesh Heart Journal 2024; 39(2): 117-120

Association of Fragmented QRS Complex with Short Term Outcome in Patients with Acute ST-Elevation Myocardial Infarction

Background: Acute ST-elevated myocardial infarction is a life-threatening condition. Presence of fragmented QRS (fQRS) after acute STEMI is associated with alteration of myocardial activation due to myocardial scar and myocardial fibrosis. Previous studies have suggested that fQRS in acute STEMI is associated with increased mortality, morbidity, sudden cardiac death and recurrent adverse cardiovascular events. The study was designed to assess the association of fQRS complex with short-term outcome (in hospital and 30 days follow up) in patients with acute ST elevation myocardial infarction. Methods: This prospective cohort study was conducted in the Department of Cardiology, Dhaka Medical College Hospital among the STEMI patients who were thrombolysed. All patients underwent serial ECG at admission, within first 12 hours, at 24 hours and at 48 hours for detecting the presence of fQRS complex. Patients showing fQRS involving infarct territory within 48 h of admission were included in the “fQRS group” and those who did not develop fQRS within 48 h of admission were included in the “without fQRS” group. 114 patients had fQRS complex and 104 patients were without fQRS in their ECG. In-hospital outcomes such as: death, heart failure, significant arrhythmias (VT, VF AF, SVT, 20 AV block, CHB), cardiogenic shock were recorded. Among the study patients, sixteen patients were lost to follow up in 30 days of index hospitalization. Finally, 202 patients were tracked for follow up regarding death or re hospitalization information by personal contact or over telephone. Statistical analysis was performed using the statistical package for social science (SPSS) 21.0 software for windows. Results: Appearance of fQRS complex occurred at admission, within first 12 hours, 24 hours and 48 hours in 53.5%, 23.7%, 14.9% and 7.9% cases respectively. During index hospitalization, development of cardiogenic shock (27.19% vs 11.54%), heart failure (23.68% vs 9.62%) and significant arrhythmias were significantly higher in fQRS group (42.10% vs 11.53%, p&lt;0.05). Although mean duration of hospitalization was similar in both groups (p&gt;0.05), but in-hospital mortality was higher in fQRS group (11.40% vs 3.85%, p&lt;0.05). Rate of re-hospitalization was significantly higher in patients with fQRS complex (21.69% vs 7.29% p&lt;0.05). Overall mortality within 30 days of index hospitalization follow-up also differs significantly in presence of fQRS complex (19.81% vs 5.2%; p =0.006). Conclusion: Presence of fQRS complex is associated with adverse short-term outcome in patients with acute ST elevation myocardial infarction. Hence, these patients need more aggressive and early invasive treatment to reduce morbidity and mortality. Bangladesh Heart Journal 2024; 39(2); 93-101

Clinical and Angiographic Profile of Non-ST Elevation Myocardial Infarction Patients with Multivessel Disease: A Study in a Tertiary Care Hospital in Bangladesh

Background: Non-ST elevation myocardial infarction (NSTEMI) is a type of acute coronary syndrome without ST-segment elevation on electrocardiography. Many non-ST elevation myocardial infarction patients have multivessel disease, which leads to worse outcomes compared to single-vessel disease. Their clinical and angiographic profiles provide valuable insightf into the nature, severity, and treatment of this common cardiac condition. This study aimed to evaluate the clinical and angiographic profiles of non-ST elevation myocardial infarction patients with multivessel disease. Methods: This prospective study was conducted in the Department of Cardiology, National Heart Foundation Hospital and Research Institute, Dhaka, Bangladesh from September 2022 to August 2023. The study enrolled 270 consecutive patients with NSTEMI. Coronary angiography and electrocardiogram were used in assessing the disease condition. The data were analyzed using SPSS version 23.0. Results: The mean age of total participants was 54.31 ±10.54 years and most of them were male (77.8%). Majority of the patients had hypertension (68.1%), diabetes mellitus (59.3%), and dyslipidemia (58.5%). In the clinical assessment, 89.6% of patients had femoral access, 31.1% had a bifurcation lesion, 8.1% showed calcification, and 22.6% had a left main lesion. Stents were used in 41.9% of cases, with a mean total stent length of 55.8 ±26.9 mm. The mean left ventricular ejection fraction was 49.10 ±7.3%. Among the major culprit vessel involvements identified, 6% involved the left main (LM) artery, 56% involved the left anterior descending (LAD) artery, 34% involved the left circumflex (LCX) artery, and 39% involved the right coronary artery (RCA). Regarding the final angiographic findings among the total participants, double vessel disease (DVD) was observed in 40% of cases, while triple vessel disease was observed in 60% of cases. Conclusion: The increased prevalence of triple vessel disease among non-ST elevation myocardial infarction patients underscores the importance of heightened vigilance among healthcare providers and policymakers. Understanding the clinical and angiographic profiles of these patients is essential for effective management strategies.

Value of Glycemic Dispersion Index in Predicting Major Adverse Cardiovascular Events in Diabetic Patients with Concomitant Acute Coronary Syndrome.

This investigation aims to assess the predictive value of the glycemic dispersion index (GDI), calculated by incorporating glycated hemoglobin, fasting plasma glucose, and 2-hour postprandial plasma glucose, in predicting major adverse cardiovascular events (MACE) within a 12-month timeframe for diabetic patients with concomitant acute coronary syndrome (ACS). A retrospective study was conducted on 3261 diabetic patients with ACS who were hospitalized in the Department of Cardiology, the Sixth Affiliated Hospital of Kunming Medical University, from January 2016 to July 2022. Based on the inclusion and exclusion criteria, 512 patients were ultimately enrolled in the study. Their general information and laboratory test indicators were collected, and the occurrence of MACE within 12 months after admission was followed up and recorded for the enrolled patients, With the last follow-up having been concluded on July 31, 2023. The enrolled patients were stratified into four groups (Q1, Q2, Q3, Q4) based on their GDI values, from the lowest to the highest. Cox proportional hazards regression analysis and Kaplan-Meier survival analysis were employed to investigate the risk factors associated with MACE occurrence across these groups and to assess the cumulative risk of MACE over time within each group. The percentages of enrolled patients experiencing MACE in groups Q1 to Q4 were 10.16%, 12.50%, 15.63%, and 16.41%, respectively. GDI independently predicted the hazards for MACE in enrolled patients. The cumulative risk of MACE over time was considerably more significant in those with a GDI>4.21 than those with a GDI≤4.21. The elevated GDI is correlated with an augmented risk of MACE in diabetic patients with concomitant ACS, thereby serving as an early indicator for assessing the unfavorable clinical prognosis of patients. This study offers novel insights into glycemic variability monitoring, enhancing prevention and treatment strategies for cardiovascular disease in people with diabetes.

Association Between Low Serum HDL Levels and Severity of Coronary Artery Disease Among Patients with Non-ST Elevated Myocardial Infarction

Introduction: Coronary artery disease is one of the leading causes of non-communicable diseases related deaths worldwide. Decreased serum high-density lipoprotein level are associated with an increased severity of coronary artery disease. Present study aims to evaluate the association between this low HDL level and the severity of coronary artery disease assessed by SYNTAX Score in patients with non-ST elevation Myocardial infarction. Materials &amp; Methods: This was a cross sectional study conducted in the Department of Cardiology at National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, from May 2020 to April 2021, on 170 admitted adult patients of non-ST elevated myocardial infarction undergoing coronary angiogram. Study population was divided in two groups; Group-I: Respondents with HDL level ≥ 40 mg/dl, Group-II: Respondents with HDL level &lt; 40 mg/dl. Transthoracic echocardiography was done before coronary angiography. All coronary lesions with diameter stenosis &gt; 50% in vessels &gt; 1.5 mm was scored, using the SYNTAX algorithm. A low score was defined as ≤ 22, an intermediate score as 23 to 32, and a high score as ≥ 33. To determine statistical significance, Chi-square test and independent sample t-test were considered according to applicability. P value of &lt; 0.05 was considered statistically significant. Results: Highest proportion of respondents were from age group 51 – 60 years, 48.2% and 43.5% for group-I and group-II respectively. Study population was male predominant, 88.2% among patients from group-I and 83.5% among patients from group-II. Smoking was the most prevalent risk factor for group-I patients at 58.8%. Hypertension was the most prevalent risk factor for group-II patients at 45.9%. Mean total cholesterol, low-density lipoprotein and high-density lipoprotein were higher among patients from group-I than group-II and these differences were statistically significant (p &lt; 0.05). Mean triglycerides was higher among patients from group-II than group-I and this difference was statistically significant (p &lt; 0.05). Triple vessel was more prevalent (36.5% vs 22.4%) among patients from group-II than group-I and this difference was statistically significant (p &lt; 0.05). Mean SYNTAX score (SS) was higher among patients from group-II than group-I, 17.4 ± 8.6 and 11.5 ± 8.4 respectively, and this difference was statistically significant (p &lt; 0.05). There was strong negative correlation between HDL level and Syntax score (r = - 0.299, p &lt; 0.05). Conclusion: Present study demonstrated significant negative correlation between low serum HDL levels with severity of coronary artery disease among patients with non-ST elevated myocardial infarction. Serum HDL levels can be used as a predictor for the severity of coronary artery disease among such patients. Bangladesh Heart Journal 2024; 39(2): 138-143
