Objective: To determine the status of malnutrition and growth failure in cyanotic and acyanotic congenital heart diseases with and without pulmonary hypertension. Study Design: Cross sectional study. Place and Duration of Study: Department of Pediatric Cardiology, National Institute of Cardiovascular Diseases, Tando Muhammad Khan, Pakistan, from Jan 2020 to Oct 2021. Methodology: A total of 250 children, with echocardiography confirmed congenital heart disease, of both genders and aged below 5 years were included. All cases were divided into 4 groups, these being, acyanotic congenital heart disease with PH, acyanotic congenital heart disease without pulmonary hypertension, cyanotic congenital heart disease with pulmonary hypertension and cyanotic Congenital heart disease without pulmonary hypertension. Gender, age, body weight, height, area of residence and malnutrition status were determined in all cases and compared in between study groups. Results: There were 41(16.4%) patients with acyanotic PH, 115(46.0%) acyanotic without PH, 34(13.6%) cyanotic with pulmonary hypertension and 60(24.0%) cyanotic without pulmonary hypertension among a total of 250 cases. Significant differences were noted in terms of age, weight, and height among different study groups (p<0.001). Nutritional status as normal was noted in 51(20.4%) cases, mild malnutrition in 50(20.0%), moderate malnutrition in 65(26.0%) and 84(33.6%) with severe malnutrition. Children having cyanotic congenital heart disease and pulmonary hypertension were also found to have failure to thrive (p=0.009). Conclusion: Malnutrition and growth failure were found to be very prevalent among children with CHDs under the age of 5 years. Malnutrition was significantly more pronounced among children having cyanotic CHDs with PH.

To determine the distribution pattern and possible reasons of delayed diagnosis of congenital heart disease in adult population. The analytical, cross-sectional study was conducted at the Department of Paediatric Cardiology, National Institute of Cardiovascular Diseases, Karachi, from July to December 2021, and comprised patients of either gender aged 18 years and above with congenital heart disease confirmed by echocardiographic examination. Age, gender, weight, height, provincial affiliation, marital status, number of children, if any, duration of disease and New York Heart Association classification were noted on a predesigned proforma. Patterns of congenital heart disease types and reasons behind delayed diagnosis, if noted, were recorded. Data was analysed using SPSS 26. Of the 129 patients, 68(52.7%) were males. The overall mean age was 25.8±9.8 years. Mean age at the time of diagnosis was 12.4±14.8 years. There were 91(70.5%) cases with delayed diagnosis. There was no significant gender difference with respect to delayed diagnosis (p>0.05). Delayed referral 39(42.9%), delayed consultation 22(24.2%), delayed diagnosis by the doctor 21(23.1%), and social factors 9(9.9%) were the most frequent reasons behind delayed diagnosis. Ventricular septal defect was the most frequently defect 38(29.5%), followed by Tetralogy of Fallot 32(24.8%). Right ventricular dysfunction was the most common complication of delayed diagnosis 35(27.1%). Delayed diagnosis of congenital heart disease was reported in over two-thirds of the cases, with ventricular septal defect being the most frequent type of defect, and delayed referral being the most common reason.

Management Strategies and Outcomes of Type 2 Diabetes in Urban and Rural Populations of Bangladesh

Introduction: Type 2 diabetes (T2D) is a chronic metabolic disorder marked by insulin resistance and poses significant health risks, including cardiovascular diseases, vision impairment, nerve damage, and kidney failure. The disease is linked to a reduced life expectancy and increased risks for complications like dementia and cancer, highlighting the urgent need for effective management strategies tailored to urban and rural populations. Aim of the study: This study aimed to identify the management strategies and outcomes of T2D in urban and rural populations of Bangladesh. Methods: This cross-sectional study was conducted in the Department of Anaesthesia Analgesia and Intensive Care Medicine, National Institute of Cardiovascular Disease and Hospital (NICVD). Dhaka, Bangladesh during the period from July 2023 to Jun 2024. A total of 200 participants were included in the study, with 100 patients from urban areas and 100 from rural areas. The study encompassed both male and female participants, who underwent treatment in both indoor (hospital-based) and outdoor (outpatient) settings. Result: A total of 200 participants were included in the study, with 100 patients from urban areas and 100 from rural regions. Among urban respondents, 35% were aged 20-30, while the rural group had a higher representation in this age group at 45%. The study revealed that individuals with higher education levels in rural areas had a lower prevalence of T2D, while overweight participants had a higher incidence in both urban and rural settings. In rural regions, the risk of T2D was notably higher among those who consumed caffeinated drinks and were less physically active, while these factors did not significantly influence T2D risk in urban populations. Additionally, urban participants exhibited a correlation between T2D and hypertension. Conclusion: Our study presents a comprehensive strategy to tackle the rising prevalence of T2D in urban and rural areas. Key elements include promoting...

In-Hospital Outcomes of Patients with Non-ST Elevation Myocardial Infarction Undergoing Early Invasive Percutaneous Coronary Intervention

Methodology: A cross-sectional study was conducted in the Adult Cardiology Department at the National Institute of Cardiovascular Diseases (NICVD) in Karachi, Pakistan, from August 2019 to February 2020. The study included 165 patients, both male and female, aged 40 to 75 years, who presented with NSTEMI and underwent early invasive PCI. All patients were either admitted through the emergency department or referred from outpatient services at NICVD. Comprehensive medical assessments were performed, and relevant medical history and clinical details were documented. PCI procedures were conducted under the supervision of experienced consultant cardiologists with over five years of procedural expertise. The primary outcomes evaluated were the incidence of cardiogenic shock, heart failure, and in-hospital mortality. Results: Of the 165 patients included in the study, 125 (75.8%) were male, with a mean age of 56.6±7.72 years and a mean BMI of 26.5±3.8 kg/m². Hypertension was prevalent in 100 (60.6%) patients, while 78 (47.3%) had diabetes mellitus. A history of smoking was reported in 70 (42.4%) patients. Heart failure emerged as the most common in-hospital adverse outcome, occurring in 25 (15.2%) patients, followed by cardiogenic shock in 9 (5.5%) patients, and in-hospital mortality in 20 (12.1%) patients. Conclusion: Among patients undergoing early invasive PCI following NSTEMI, heart failure was the most frequent adverse in-hospital outcome, followed by mortality and cardiogenic shock. These findings underscore the importance of vigilant monitoring and management of high-risk NSTEMI patients during the early stages of PCI intervention.

Factors Contributing to Re-Hospitalization in Heart Failure Patients at a Tertiary Care Center in Karachi, Pakistan

Objectives: To identify the factors associated with re-hospitalization of heart failure (HF) patients at a tertiary care cardiac center in Karachi, Pakistan. Methodology: This cross-sectional study was conducted at the emergency department of the National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan, from February 2021 to August 2021. A total of 307 adult patients, aged ≥18 years, diagnosed with HF of any etiology for at least 4 weeks, were included. Patients were assessed for socio-demographics, risk profiles, and various reasons for re-hospitalization. Data was recorded using a pre-designed questionnaire by the researcher and analyzed with SPSS version 23. Results: The mean age of the patients was 59.20±13.27 years, with the majority being male (66.8%). The most common reason for re-hospitalization was non-compliance with treatment (42.7%), followed by lack of regular follow-up (39.4%). Additionally, 28.3% of patients showed non-adherence to fluid intake, and 29% presented with myocardial ischemia. Significant associations were found between 90-day readmission and non-adherence to fluid restriction (p=0.046) as well as lack of regular follow-up (p=0.024). Conclusion: Re-hospitalization of HF patients is primarily associated with non-compliance with medication, lack of regular follow-up, non-adherence to fluid restriction, and myocardial ischemia. Enhanced patient counseling on treatment adherence and lifestyle modifications is essential to reduce the rate of HF-related re-hospitalizations.

ASSOCIATION OF RADIAL ARTERY ACCESS WITH REDUCED INCIDENCE OF ACUTE KIDNEY INJURY

Acute kidney injury (AKI) is a serious complication following cardiac procedures, leading to increased morbidity and mortality. The choice of vascular access site may influence the incidence of AKI, with radial artery access potentially offering protective benefits compared to femoral artery access. Objective: To evaluate the association between radial artery access during cardiac procedures and the incidence of acute kidney injury among patients. Methods: This retrospective cohort study was conducted at the National Institute of Cardiovascular Disease from January 2023 to January 2024. A total of 370 patients who underwent cardiac procedures were included, comprising 200 patients in the radial artery access group and 170 in the femoral artery access group. Data were collected retrospectively from medical records, including demographic information, baseline renal function, procedural details, and serum creatinine levels before and after the procedure. The incidence of AKI was determined based on established criteria for changes in serum creatinine. Statistical analyses were performed using appropriate tests, with a significance level set at p < 0.05. Results: Patients in the radial artery access group had a shorter average hospital stay (2.5 ± 1.2 days) compared to the femoral group (3.8 ± 1.5 days, p = 0.001). The mortality rate was lower in the radial group (1.5%) versus the femoral group (4.1%), although this difference was not statistically significant (p = 0.09). The incidence of major adverse cardiovascular events (MACE) was 2.5% in the radial group compared to 5.9% in the femoral group (p = 0.07). Acute kidney injury occurred in 10.0% of patients in the radial artery access group (20 out of 200) versus 17.6% in the femoral artery access group (30 out of 170), indicating a significant reduction in AKI incidence with radial access. Conclusion: Using radial artery access during cardiac procedures significantly reduces the incidence of acute kidney injury compared to femoral artery access. These findings support the preference for radial artery access to minimize the risk of AKI and improve patient outcomes.

Assessment of QTc-interval Prolonging Medication Utilization and Associated Potential Drug-Drug Interactions in Hospitalized Cardiac Patients: A Cross-Sectional Study in Cardiology

Background: Several medications are linked to QTc-interval prolongation and torsades de pointes (TdP), a risk that is more common among hospitalized patients due to polypharmacy and associated QTc-interval-prolonging drug-drug interactions (QTc-pDDIs). Objective: This study aimed to identify the prevalence of QTc-interval-prolonging drug (QTc-Drug) utilization and QTc-pDDIs among postoperative cardiac patients admitted to the National Institute of Cardiovascular Diseases (NICVD). Method: We conducted a cross-sectional study at the NICVD, reviewing patients' medication charts for the use of QTc-Drugs and QTc-pDDIs. The CredibleMeds list was used to identify drugs associated with QTc-interval prolongation, while Micromedex Drug-Int.® and Lexicomp Interact® were utilized to screen for QTc-pDDIs. Results: A total of 384 patients, with an average age of 48.9 ± 13.9 years, were included in the study. On average, patients used 10.3 ± 1.7 medications. Of the 3,956 medications prescribed, 22.9% were QTc-Drugs. The most frequently used QTc-Drug classes were diuretics (69.3%), anti-emetics (61.5%), and proton pump inhibitors (51.0%). Overall, 99.7% of patients received at least one QTc-Drug. The most frequent QTc-pDDI was ciprofloxacin-domperidone (7.6%), classified as major by Micromedex and a category B interaction by Lexicomp. Conclusion: The prevalence of QTc-Drugs was very high among postoperative cardiac patients, with nearly all patients (99.7%) receiving at least one QTc-Drug. The most common QTc-pDDI was ciprofloxacin-domperidone (7.6%), identified as a major interaction by Micromedex and a category B interaction by Lexicomp. Category X (contraindicated) QTc-pDDIs should be avoided in hospitalized patients.

To determine the level of health-related quality of life among patients treated for ischaemic heart disease in two public-sector tertiary care settings. The analytical cross-sectional study was conducted from July to September 2021 at two tertiary care hospitals in Karachi after approval from the ethics review boards of the National Institute of Cardiovascular Diseases and the Dow University of Health Sciences, and comprised patients of either gender treated for ischaemic heart disease after being diagnosed within the preceding year who were coming for follow-up in the outpatient department. Data was collected using the short version of the World Health Organisation quality of life tool. Association of socio-demographic and clinical variables with health-related quality of life was explored. Data was analysed using SPSS 21. Of the 300 patients aged 25-85 years, 212(70.7%) were males and 88(29.3%) were females. The mean total quality of life score was 6.1+/-1.4, while mean general health was 52.6+/-10.5. The lowest score among quality of life subscales was for environmental 44.7+/-15.1, while the highest score was for psychological 60.1+/-10.7 domains. Quality of life was significantly associated with patients' age, education, comorbidities, marital status, monthly income, body mass index, activities of daily living and smoking status (p<0.05). ischaemic heart disease patients had average health-related quality of life in all domains, but showed low quality of life in the environmental domain.

Association of Preoperative Neutrophil to Lymphocyte Ratio with Early Postoperative Acute Kidney Injury Following Isolated Off-Pump Coronary Artery Bypass Grafting

Objective: Acute kidney injury (AKI) is a frequent complication after off-pump coronary artery bypass grafting (OPCAB) that complicates recovery, increases treatment cost and mortality. Neutrophil to lymphocyte ratio (NLR) is a systemic inflammatory marker easily derived from complete blood count that has many prognostic potentials. The purpose of this study was to evaluate if there is an association of preoperative NLR with early postoperative AKI following isolated OPCAB. Methods: This cross-sectional study was carried out in the Department of Cardiac Surgery, National Institute of Cardiovascular Diseases (NICVD) on a total of 60 patients aged 31-70 years with no preoperative renal dysfunction undergoing isolated OPCAB between August 2021 and July 2022. Group A included 30 patients with preoperative NLR &lt; 2.65 and Group B included 30 patients with preoperative NLR ≥ ≥≥2.65. Patients were monitored for development of early postoperative AKI according to serum creatinine criteria of Kidney Disease Improving Global Outcomes (KDIGO) 2012 guideline. Results: Two patients from group A and twenty patients from group B developed early postoperative AKI (p &lt; 0.001). Events of AKI were significantly higher in group B patients at all postoperative time points. Multivariate binary logistic regression analysis revealed preoperative NLR ≥ ≥≥2.65 as an independent predictor of early post OPCAB AKI (p = 0.004, OR = 13.746). In receiver operating curve (ROC) analysis area under curve (AUC) was 0.933 (95% CI 0.874-0.992, p &lt; 0.001). It showed 90.91% sensitivity and 73.7% specificity at the pre-set cut off value of NLR at 2.65 where optimal predictability of post-OPCAB AKI occurred with 66.67% positive predictive value, 93.33% negative predictive value and 80% accuracy. Conclusion: Preoperative NLR is significantly associated with early postoperative AKI following isolated OPCAB and therefore it should be incorporated in routine clinical practice for early prediction of AKI and implementing timely preventive strategies.

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

The Cost-Effectiveness of Early Invasive Procedures for Acute Coronary Syndrome in Low-Income Regions: A Prospective Cohort Study in Pakistan.

Background Acute coronary syndrome (ACS) is a significant cause of mortality and morbidity globally, necessitating effective intervention strategies. Early invasive procedures such as percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are often recommended for high-risk patients. However, their cost-effectiveness in low-income regions remains uncertain, particularly in Pakistan, where healthcare resources are limited. Objective This study aims to evaluate the cost-effectiveness of early invasive procedures compared to standard care for ACS in low-income regions of Pakistan. Methods We conducted a prospective cohort study from January 1, 2021, to January 31, 2021, at four major hospitals in Pakistan: Army Cardiac Center Combined Military Hospital (CMH) Lahore, National Institute of Cardiovascular Diseases in Karachi, Lady Reading Hospital in Peshawar, and Mardan Medical Complex. The participants included 436 patients diagnosed with ACS aged 18 years or older and presenting within 24 hours of symptom onset. The patients were divided into two groups: the early invasive procedure group (n = 218) and the standard care group (n = 218). The primary outcome was the 30-day mortality rate. Secondary outcomes included recurrent myocardial infarctions, hospital readmissions, healthcare costs, and procedural complications. Data were analyzed using SPSS version 25.0 (IBM SPSS Statistics, Armonk, NY), employing descriptive statistics, chi-square tests, independent t-tests, and Kaplan-Meier survival analysis. Results The early invasive procedure group showed a mortality rate of 18 (8%) compared to 33 (15%) in the standard care group, demonstrating a significant reduction in mortality (p = 0.01). Additionally, the average healthcare cost was significantly lower in the early invasive group, with mean costs of Pakistani rupee (PKR) 187,200 (US dollar {USD} 1,200) compared to PKR 280,800 (USD 1,800) in the standard care group (p < 0.01). Recurrent myocardial infarctions occurred in 11 (5%) of the early invasive group versus 26 (12%) in the standard care group (p < 0.05). Hospital readmission rates were lower in the early invasive group, 22 (10%) compared to 39 (18%) in the standard care group (p < 0.05). Healthcare costs were significantly lower in the early invasive group, with mean costs of PKR 187,200 (USD 1,200) compared to PKR 280,800 (USD 1,800) in the standard care group (p < 0.01). Conclusion Early invasive procedures for ACS significantly improve survival rates, reduce complications, and lower healthcare costs in low-income regions of Pakistan. These findings suggest that such strategies should be considered in resource-limited settings to optimize patient outcomes and healthcare resource utilization.

Outcome of Early and Late Onset Fontan Operation in Patients with Univentricular Heart Repair

Objective: To determine the outcome of early and late-onset Fontan operation in patients with univentricular heart repair. Study Design: Quasi-experimental study. Place and Duration of the Study: Department of Paediatric Cardiology, National Institute of Cardiovascular Diseases, Karachi Pakistan, from Jan 2019 to Dec 2021. Methodology: During the study period, 121 patients of both genders, up to any age, with functionally univentricular hearts and who planned to undergo Fontan procedures were included. All cases were divided into two groups, Group-A had patients who underwent extra-cardiac Fontan at age ≤6 years, while Group B had patients who underwent extra-cardiac Fontan at age &gt;6 years. Pre-procedure diagnosis, demographic, anatomic and hemodynamic characteristics, post-Fontan procedure morbidity and mortality were noted. Results: As per inclusion/exclusion criteria, 121 cases underwent Fontan surgery during the study period. There were 61(50.4%) male patients. Overall, the mean age was 7.02±4.6 years. Seventy-six 76(61.2%) cases were in Group-A and 45(38.8%) in Group-B. Mortality (within 30 days post-surgery) was reported in 11(9.1%) patients. Except for the mean duration of chest tube drainage ((0.010), there was no difference in terms of post-Fontan surgery outcomes between both study groups (p&gt;0.05). Conclusion: The age of the patients at the time of the Fontan procedure did not affect the outcomes.

Impact of Early Invasive Strategy on Left Ventricular Function Recovery in Acute Myocardial Infarction Patients in Pakistan.

Background Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide, particularly in low- and middle-income countries like Pakistan, where healthcare resources are limited. Early Invasive Strategy (EIS), typically involving percutaneous coronary intervention (PCI), has been shown to improve outcomes in AMI patients. However, the effectiveness of EIS in resource-limited settings, such as Pakistan, remains under-explored. Objective This prospective observational cohort study aimed to assess the impact of an Early Invasive Strategy (EIS) on left ventricular (LV) function recovery in acute myocardial infarction (AMI) patients in Pakistan. The primary objective was to measure the change in left ventricular ejection fraction (LVEF) over six months. Secondary objectives included evaluating mortality, rehospitalization rates, and incidences of major adverse cardiovascular events (MACE). Multivariate regression analysis was employed to adjust for potential confounders. Methods The study was conducted from January to December 2023 at the National Institute of Cardiovascular Diseases (NICVD) satellite centers in Sukkur, Nawab Shah, and Khairpur. A total of 300 AMI patients presenting within 24 hours of symptom onset were included. Participants were divided into two groups: the EIS group (n = 150) received percutaneous coronary intervention (PCI) within 24 hours of admission, while the delayed treatment group (n = 150) received standard therapy, with invasive procedures performed after 24 hours if clinically indicated. Data were collected at baseline, during hospitalization, and at three- and six-months post-AMI. Results The EIS group demonstrated a significantly greater improvement in LVEF compared to the delayed treatment group (13.1% [95% CI, 10.8%-15.4%] vs. 7.5% [95% CI, 5.8%-9.2%], p < 0.001). Mortality was lower in the EIS group (3% [n = 4] vs. 9% [n = 13], p = 0.01), as were rehospitalizations for heart failure (7% [n = 10] vs. 14% [n = 21], p = 0.02) and incidences of MACE (8% [n = 12] vs. 16% [n = 24], p = 0.01). Multivariate regression analysis confirmed that EIS was independently associated with better LVEF improvement (coefficient = 5.78 [95% CI, 4.21-7.35], p < 0.001). Conclusion Early invasive treatments significantly enhance left ventricular function recovery and reduce mortality and rehospitalization rates in AMI patients in Pakistan. These findings advocate for the implementation of timely PCI interventions in resource-limited settings to improve clinical outcomes, particularly emphasizing cost-effectiveness and the availability of PCI.

Relationship of adhesion molecules (ICAM-1 and E-selectin) with ABO blood groups in patients hospitalized with acute myocardial infarction.

Adhesion molecules, sICAM-1 and sE-selectin appear to have a major role in the pathogenesis of coronary artery disease (CAD). The focus of this study was to investigate the relationship of sICAM-1 and sE-selectin with ABO blood groups in Pakistani patients hospitalized with acute myocardial infarction (AMI). In a case-control study, 116 patients of acute myocardial infarction (AMI) and 116 healthy controls (age range for both: 30 years to 70 years; both males and females) were randomly selected from the Aga Khan University and National Institute of Cardiovascular Diseases, Karachi with informed consent. The blood samples were obtained and analyzed for ABO blood groups and serum levels of sICAM-1 and sE-selectin using kit methods. Statistical tests including independent sample t-test and Two-way ANOVA were used to study the association of these adhesion molecules with blood groups in AMI patients and healthy controls. Duration of the study was from July 2021 to June 30, 2023. Mean serum levels of sICAM-1 were significantly higher in AMI patients compared to healthy controls (342±159 mg/dl vs. 227±104 mg/dl; p-value<0.001). Similarly, serum levels of sE-selectin were also significantly higher in AMI patients compared to healthy controls (53.6±26.9 mg/dl vs. 40.7± mg/dl; p-value<0.001). Moreover, mean concentrations of sICAM-1 and sE-selectin for the interaction between subject type (cases and control) and blood groups were statistically significant (p-value = 0.007 and p-value = 0.035, respectively). There is an association of adhesion molecules, sICAM-1 and sE-selectin with ABO blood groups in Pakistani patients hospitalized with AMI.

PREDICTORS OF NO-REFLOW PHENOMENON AFTER PCI IN PAKISTANI PATIENTS

The no-reflow phenomenon is a perplexing complication of PCI. It is marked by poor coronary microvascular perfusion despite successful revascularization. This condition can lead to adverse outcomes such as myocardial infarction and heart failure. Various treatments exist, including pharmacological agents and mechanical interventions, but no flow remains a significant clinical challenge. Objective: This study aims to identify predictors of the no-reflow phenomenon in Pakistani patients undergoing PCI. Methods: Conducted at the National Institute of Cardiovascular Diseases (NICVD) in Karachi from January 2020 to December 2021, this observational study included 256 patients undergoing primary PCI for acute myocardial infarction. Baseline characteristics such as age, sex, BMI, diabetes status, hypertension, smoking status, and left ventricular ejection fraction (LVEF) were recorded. The primary outcome was the incidence of no-reflow, with secondary outcomes including in-hospital mortality and heart failure. Data analysis was performed using SPSS software, with logistic regression pinpointing independent predictors of no-reflow. Results: The patients had a mean age of 58.4 ± 12.3 years, and the median was 59 years. Most patients were male (78.1%). Significant predictors of no-reflow included diabetes mellitus (OR: 2.1, 95% CI: 1.2-3.7, p=0.01), hypertension (OR: 1.8, 95% CI: 1.0-3.2, p=0.04), and reduced LVEF (OR: 1.5 per 5% decrease, 95% CI: 1.2-2.1, p&lt;0.001). Patients experiencing no-reflow had higher in-hospital mortality (11.1% vs. 4.0%, p&lt;0.05) and heart failure rates (24.1% vs. 10.4%, p&lt;0.01) compared to those with normal flow. Conclusion: Diabetes mellitus, hypertension, and reduced LVEF are significant predictors of the no-reflow phenomenon in Pakistani patients undergoing PCI. Identifying high-risk patients allows for targeted preventative strategies to improve clinical outcomes.

Association between ST-Segment Resolution Following Thrombolysis and Reperfusion of Infarct Related Artery in Coronary Angiogram in Patients with ST-Segment Elevation Myocardial Infarction

Background: ST-segment elevation myocardial infarction (STEMI) is the most critical form of acute coronary syndrome as having the worst overall prognosis. Following thrombolysis, if it is possible to reliably predict about the reperfusion status by means of a non-invasive, readily available tool like ECG, it will help the clinicians to determine the quality of reperfusion and select the next strategy of management. The aim of the study was to assess angiographic findings of TIMI flow in infarct related artery (IRA), compared to the ranges of ST-segment resolution, and determine their association to predict reperfusion in IRA. Methods: Thiscross-sectional observational study was conducted in the department of Cardiology at National Institute of Cardiovascular Diseases (NICVD), Dhaka, for 12-months following ethical approval. A total of 116 adult patients with acute STEMI who underwent thrombolysis with streptokinase were enrolled by convenient sampling method after taking written informed consent. The percent resolution of ST-segment deviation from baseline to 60 minutes following thrombolysis was compared with angiographic IRA TIMI flow grade in index hospitalization. Detailed history, thorough clinical examination and necessary investigations were carried out in each patient and recorded in predesigned structured questionnaire. Data were analyzed by SPSS 26.0. Results: The mean age of the patients was 50.8 ± 8.8 years with male predominance (77.6%). Among all, 45.7% had &gt;70% ST resolution followed by 29.3% had 30-70% and 25% had &lt;30% ST resolution. Regarding TIMI grade flow, 59.1% had grade-3, 22.7% had grade-2 and 18.2% had grade 0 or 1. TIMI grade flow significantly increased with the increased ST-segment resolution. A cut off value of ST-segment resolution ≥57.5% (AUC=0.771, 95% CI=0.684-0.858, p&lt;0.001) in the prediction of TIMI grade flow 3 showed 67.69% sensitivity, 66.67% specificity, 74.58% PPV, 58.82% NPV and 67.27% accuracy. Multivariate logistic regression shows that timing of thrombolysis, &gt;70% ST resolution showed higher odds ratio and &gt;70% ST resolution showed statistically significant p-value for predicting TIMI grade flow 2 or 3. Conclusion: ST-segment resolution in electrocardiogram following thrombolysis has significant positive association with TIMI flow of infarct related artery in coronary angiogram. However, further larger study is recommended.

Demographic data along with diagnosis, clinical presentation, echocardiographic findings, procedural outcome (successful/unsuccessful), duration of the procedure, complication (if any), post-procedural echocardiographic findings, duration of hospital stay, further treatment plan and 3-months follow up outcomes were recorded among all neonates. Results: Most common diagnosis was Dextro-Transposition of the Great Arteries with IVS observed in 14(50.0%) neonates. Procedural outcome was found to be successful among 23(82.1%) neonates. There were 19(67.9%) neonates who did not show any post-procedure complication. At 3-months follow up, improvement in blood saturation and weight gain were reported among 12(42.9%) neonates each. Overall, mortality was noted in 7(25.0%) neonates, of whom 4(57.1%) neonates were having hypoplastic left heart syndrome. Conclusion: Transcatheter atrial septostomy done in neonatal period was found to have positive outcomes. Mortality remains high among neonates undergoing transcatheter atrial septostomy having hypoplastic left heart syndrome.

Knowledge, Attitude and Practices (KAP) of Sterilization and Disinfection of Health Care Professionals in Bangladesh

&amp;lt;i&amp;gt;Background:&amp;lt;/i&amp;gt; Healthcare professionals face a constant risk of acquiring infections from patients. Exposure to blood, saliva, and sharp instruments increases their susceptibility to various infectious diseases. Proper sterilization and disinfection procedures are crucial for protecting both healthcare workers and patients. &amp;lt;i&amp;gt;Objective:&amp;lt;/i&amp;gt; This study aimed to assess the knowledge, attitude, and practices regarding sterilization and disinfection among healthcare professionals in Bangladesh.&amp;lt;i&amp;gt; Methods&amp;lt;/i&amp;gt;: A cross-sectional study was conducted at the National Institute of Cardiovascular Diseases &amp; Hospital in Dhaka, Bangladesh, from January to June 2023. A total of 81 healthcare professionals were randomly selected and participated in the study after providing verbal consent. Data collection involved a pre-structured questionnaire focusing on knowledge, attitude, and practices related to sterilization and disinfection. Statistical analysis was performed using SPSS software, and results were presented as frequencies and percentages. Ethical clearance was obtained before the study commenced. &amp;lt;i&amp;gt;Results: &amp;lt;/i&amp;gt;The study included healthcare professionals from various backgrounds, with the majority being young adults (21-25 years old). Knowledge assessment revealed a good understanding of sterilization methods, disinfection procedures, post-sterilization instrument management, and waste disposal practices. Additionally, most participants were aware of the hospital&amp;apos;s sterilization protocols and infection prevention policies. Regarding attitudes, a positive response was observed towards regular training for staff, proper use of personal protective equipment (PPE), and adherence to sterilization and disinfection guidelines. However, a minority expressed concerns about reusing disposable items. Practices reflected the positive knowledge and attitudes, with a high percentage of participants following hand hygiene protocols, using PPE, and opting for disposable equipment. However, a small number reported experiencing needle-stick injuries, highlighting a potential gap between knowledge and practice. &amp;lt;i&amp;gt;Conclusions:&amp;lt;/i&amp;gt; the study found that a majority of healthcare professionals in this setting demonstrated good knowledge, positive attitudes, and appropriate practices regarding sterilization and disinfection. However, a small knowledge, attitude, and practice gap was identified, particularly concerning needle-stick injuries. These findings suggest a need for ongoing education and reinforcement of safe practices to ensure optimal infection prevention and control in healthcare facilities.

Isolated left ventricular non-compaction: clinical characterisation of a teenage male

Isolated Left Ventricular Non-compaction (LVNC) is a type of cardiomyopathy that usually has a genetic origin. Its diagnosis is based on findings such as deep intertrabecular recesses or sinusoids and ventricular trabeculations communicating with the left ventricular cavity. LVNC was first clinically recognised almost four decades back, yet its diagnostic and management challenges persist. In this report, we present the case of an 18-year-old boy, who presented at the National Institute of Cardiovascular Diseases, Karachi, in March 2023, with complaints of dizziness, pedal oedema, and shortness of breath. Echocardiography revealed signs suggestive of LVNC, which were confirmed conclusively on Cardiovascular Magnetic Resonance (CMR) (NC/C ratio&gt;2.4). The patient underwent implantable cardioverter defibrillator (ICD) placement, was discharged after a smooth post-procedure recovery, and is doing well on follow-ups. ---Continue

Extended Balloon Inflation Technique for Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction during Stent Deployment

Background: Primary percutaneous coronary intervention (PPCI) is the preferred method for treating ST-segment elevation myocardial infarction (STEMI), but the no-reflow phenomenon remains a significant challenge. This study investigates the efficacy of prolonged balloon inflation during stent deployment to reduce the incidence of no-reflow. Objective: To assess whether extending the duration of balloon inflation during stent deployment in PPCI reduces the incidence of the no-reflow phenomenon compared to the conventional rapid inflation and deflation strategy. Methods: This randomized controlled trial enrolled 122 patients at the National Institute of Cardiovascular Diseases, Pakistan, from February 2023 to January 2024. Patients were randomly assigned to either prolonged balloon inflation (PBSG) or conventional deployment (CDSG). Results: The mean age in the PBSG was 59.83±10.10 years, and in the CDSG, it was 60.39±10.16 years. Male participants comprised 51.6%. The PBSG showed significantly lower immediate TIMI flow grades less than 3 (4.9% vs. 26.2%, P = 0.00), no-reflow incidence (0% vs. 26.2%, P = 0.00), corrected TIMI frame counts (36.96±4.25 vs. 46.13±6.82, P = 0.00), and higher ST-segment resolution ≥50% (77.0% vs. 57.4%, P = 0.02). Additionally, 59.0% in the PBSG achieved an MBG of 3 compared to 16.4% in the CDSG (P = 0.00). Conclusion: Prolonged balloon inflation during stent deployment in PPCI significantly reduces the no-reflow phenomenon and improves myocardial perfusion in patients with STEMI.
