Impact of different P2Y12 inhibitors in acute coronary syndrome patients with severe chronic kidney disease: insights from the CORALYS registry

Abstract Background The impact of the most potent P2Y12i ticagrelor and prasugrel after acute coronary syndrome in patients with chronic kidney disease (CKD) remains unclear. Most evidence on dual antiplatelet therapy (DAPT) comes from real-world study but is limited to glomerular filtration rate (GFR) under 60 ml/min whereas no data are available regarding patients with severe CKD (stages IV-V) Methods Consecutive patients with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI) and severe CKD defined as GFR under 30 ml/min not on dialysis from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of Net Adverse Clinical Events (NACE) defined as major adverse cardiac events (MACE, a composite of cardiovascular death, myocardial infarction and unplanned revascularizations) in addition to major bleedings (classified as BARC scale 3 to 5) was our primary endpoint. Overall MACE and their single components, all bleedings, major bleedings and hospitalizations for heart failure were the secondary ones. Results Of 14699 patients in the CORALYS registry, 257 presented with severe CKD not on dialysis and had available data on antiplatelet regimen at discharge. Patients were divided into two groups according to the type of P2Y12i prescribed at discharge: 193 (75.1%) were given clopidogrel while 64 (24.9%) with ticagrelor or prasugrel. Our populaiton was predominantly male (153, 59.5%) with an average age 75.8 ± 10.9 years old. Average GFR was 21.8 ± 6.3 ml/min. Over a median follow-up of 459 days, Ticagrelor and Prasugrel were associated to lower rates of NACE compared to Clopidogrel (39.9% vs 25.0%, p=0.036). This was mainly driven by an excess of both CV mortality (31.1% vs 6.3%) and myocardial infarction (20.7% vs 9.4%) reported in the clopidogrel group. No difference was reported regarding overall bleeding events (5.7% vs 4.6% with clopidogrel and new P2Y12i respectively, p=0.81) and major bleedings (1.7% vs 4.6% with clopidogrel and new P2Y12i respectively, p=0.15). At multivariate Cox regression analysis DAPT with Ticagrelor/Prasugrel resulted independently associated with a lower risk of NACE (Adj Hr 0.41, 95%CI 0.23-0.74, p=0.003) whereas left main involvement or multivessel coronary disease led to higher risk of NACE (Adj HR 1.96 95%CI 1.21-3.18, p=0.006) Conclusions In ACS patients treated with PCI with severe CKD ticagrelor and prasugrel were associated to lower risk of NACE, MACE, CV death and myocardial infarction compared to clopidogrel. No significative difference was reported in overall and major bleedings despite a relative increase of major bleedings in the group treated with Ticagrelor or Prasugrel.

Glucose-Lowering Drugs with Proven Cardiovascular Benefit Following Acute Coronary Syndrome in Patients with Type 2 Diabetes: Treatment Gaps and Outcomes.

Background: Real-world data on the implementation and prognostic impact of glucose-lowering drugs with proven cardiovascular benefits in patients with type 2 diabetes (T2D) following acute coronary syndrome (ACS) are limited. We investigated the utilization and treatment patterns of sodium-glucose contrasporter-2 inhibitors (SGLT2Is) and glucagon-like peptide-1 recepto-agonists (GLP1RAs) in patients with T2D experiencing ACS and analyzed their association with mortality and major adverse cardiovascular events (MACEs) including recurrent ACS, acute revascularization, heart failure, or ischemic stroke. Methods: We carried out a retrospective analysis of 9756 patients with T2D from a nationwide healthcare organization in Israel who were hospitalized with ACS between 01/2019 and 01/2022. Drug prescriptions were estimated pre-hospitalization, 90 days, and 1 year following hospitalization. The association between SGLT2I and/or GLP1RA treatment with MACE and mortality was investigated using a time-dependent Cox regression analysis with multivariable adjustment. Results: The prescription rates (pre-hospitalization, 90 days, and 1 year post-hospitalization) of GLP1RAs were 13%, 13.2%, and 18%, and those of SGLT2Is were 23.9%, 33.6%, and 42.7%, respectively. At 1 year, 13.9% of patients were prescribed both treatments. The use of SGLT2Is and/or GLP1RAs was higher in younger age groups and increased from 2019 to 2021 (38.1% to 59.2%). The adjusted hazard ratio for the association of pre- or post-hospitalization SGLT2I and/or GLP1RA treatment with mortality and MACE was 0.724 (0.654-0.801) and 0.974 (0.909-1.043), respectively. Conclusions: In the real-world practice of treating patients with T2D experiencing ACS, the implementation of SGLT2Is, particularly GLP1RAs, was suboptimal when prescribed both early and 1 year following hospitalization, emphasizing the need to improve medical care. Treatment with SGLT2Is and/or GLP1RAs was associated with a favorable impact on mortality but not MACE.

Comparison of Diagnostic Parameters of Acute Coronary Syndromes in Patients with and without Cancer: A Multifactorial Analysis.

The simultaneous occurrence of cancer and acute coronary syndromes (ACSs) presents a complex clinical challenge. This study clarifies variances in diagnostic parameters among ACS patients with and without concurrent cancer. This retrospective study included 320 individuals diagnosed with ACS, stratified equally into two cohorts-one with cancer and the other cancer-free. We evaluated risk factors, symptom profiles, coronary angiography results, echocardiographic evaluations, and laboratory diagnostics. Statistical analysis was performed using Student's t-test, the Mann-Whitney U test, and the chi-square test. Cancer patients were older (mean age 71.03 vs. 65.13 years, p < 0.001) and had a higher prevalence of chronic kidney disease (33.1% vs. 15.0%, p < 0.001) but a lower prevalence of hyperlipidemia (59.7% vs. 82.5%, p < 0.001). Chest pain was less frequent in cancer patients (72.5% vs. 90%, p < 0.001), while hypotension was more common (41.9% vs. 28.8%, p = 0.022). NSTEMI was more common in cancer patients (41.9% vs. 30.6%, p = 0.048), while STEMI was less common (20.6% vs. 45.3%, p < 0.001). RCA and LAD involvement were less frequent in cancer patients (RCA: 18.1% vs. 30.0%, p = 0.018; LAD: 18.8% vs. 30.0%, p = 0.026). This study demonstrates differences in the clinical presentation of ACS between patients with and without cancer. Cancer patients were less likely to present with chest pain and more likely to experience hypotension. Additionally, they had a higher prevalence of chronic kidney disease and they were less likely to have hyperlipidemia. These findings highlight the need for a careful approach to diagnosing ACS in oncology patients, considering their distinct symptomatology.

Diagnostic accuracy of point-of-care cardiac ultrasound for acute coronary syndromes in patients presenting with chest pain to the emergency department: a single-center prospective study.

The diagnostic accuracy of focused cardiac ultrasound (FoCUS) performed in patients presenting to the emergency department (ED) with chest pain is currently unknown. The objective of this study was to assess the diagnostic accuracy of regional wall motion abnormalities detected with FoCUS for non-ST-elevation acute coronary syndrome (NSTE-ACS) diagnosis. A Single-center prospective observational study conducted in 2022 in the ED of the University Hospital Careggi, Italy. Adult patients presenting to the ED with acute nontraumatic chest pain were enrolled, irrespective of the presence of previous regional wall motion abnormalities. Patients with ST-segment elevation myocardial infarctions and patients with hemodynamic instability were excluded. FoCUS was performed at presentation by a trained ED physician. The final diagnosis of NSTE-ACS vs. alternative diagnosis was adjudicated by an ED physician blinded to FoCUS results after a 30-day follow-up. To assess if regional wall motion abnormalities were an independent predictor of NSTE-ACS, a multivariable logistic regression model was built. Diagnostic performance measures were calculated. A sensitivity analysis considering only type-1 NSTEMIs (i.e. plaque rupture/thrombosis) was conducted. Among 686 patients, NSTE-ACS was adjudicated in 106 (15.5%) patients, 67 of which were NSTEMIs. A total of 87 (12.7%) patients had regional wall motion abnormalities detected by FoCUS, which were an independent predictor of NSTE-ACS in the multivariable logistic regression analysis. Regional wall motion abnormalities had a sensitivity of 42.5% (33.0-51.9), a specificity of 92.8% (90.6-94.9), a negative predictive value of 89.8% (87.4-92.2), and a positive predictive value of 51.7% (41.2-62.2), for NSTE-ACS. Results were consistent in the sensitivity analysis. In ED patients with chest pain and no ST elevation, the detection of regional wall motion abnormalities was a predictor of NSTE-ACS. Despite a high specificity, which indicated a possible role of FoCUS in the rule-in of NSTE-ACS, sensitivity was too low to allow a safe rule-out using FoCUS results alone.

Prediction of acute coronary syndrome in patients with myeloproliferative neoplasms.

Patients with myeloproliferative neoplasms (MPN) are exposed to a higher risk of cardiovascular disease, especially cardiovascular calcification. The present research aimed to analyze the clinical features and coronary artery calcium score (CACS) in MPN patients, and construct an effective model to predict acute coronary syndrome (ACS) in MPN patients. A total of 175 MPN patients and 175 controls were recruited from the First Affiliated Hospital of Ningbo University. Based on cardiovascular events, the MPN patients were divided into the ACS group and the non-ACS group. Multivariate Cox analysis was completed to explore ACS-related factors. Furthermore, ROC curves were plotted to assess the predictive effect of CACS combined with white blood cells (WBC) and platelet for ACS in MPN patients. The MPN group exhibited a higher CACS than the control group (133 vs. 55, P < 0.001). A total of 16 patients developed ACS in 175 MPN patients. Compared with non-ACS groups, significant differences in age, diabetes, smoking history, WBC, percentage of neutrophil, percentage of lymphocyte, neutrophil count, hemoglobin, hematocrit, platelet, lactate dehydrogenase, β 2-microglobulin, and JAK2V617F mutation were observed in the ACS groups. In addition, the CACS in the ACS group was also significantly higher than that in the non-ACS group (374.5 vs. 121, P < 0.001). The multivariable Cox regression analysis identified WBC, platelet, and CACS as independent risk factors for ACS in MPN patients. Finally, ROC curves indicated that WBC, platelet, and CACS have a high predictive value for ACS in MPN patients (AUC = 0.890). CACS combined with WBC and platelet might be a promising model for predicting ACS occurrence in MPN patients.

Coronary heart disease and tuberculosis: an unnoticed syndemia. Review of literature and management proposal.

Tuberculosis is an increasing disease that affects about one-third of the global population. In line with the rise of tuberculosis, cardiovascular disease has shown a similar trend, with ischemic coronary heart disease becoming the leading cause of death worldwide. Based on the literature, a relationship can be drawn between tuberculosis and ischemic coronary heart disease through their shared multiple risk factors and a possible pathophysiological substrate linking them. The presentation of these two conditions reported so far is varied: it has been found as the onset of acute coronary syndrome in patients with active tuberculosis, the progressive development of coronary atherosclerosis in patients with latent tuberculosis, among others. Given this possible link and the progressive increase in their incidence rates, we can assert that we are facing an unnoticed syndemic, with their concurrent management posing a challenge due to significant pharmacological interactions. The purpose of this review is to clarify this possible link, propose an approach for diagnosis, and provide a treatment algorithm for the entire spectrum of coronary disease coexisting with tuberculosis according to the current available literature.

What if youth is not enough? Acute coronary syndrome in young patients

Abstract Funding Acknowledgements None. Background Acute Coronary Syndromes (ACS) are the leading cause of mortality in Spain. Further research is needed in order to know risk factors and outcomes in young patients so that medicians could optimize their management and prevention. Purpose Identifying risk factors, clinical characteristics and short-term outcomes in Acute Coronary Syndrome in patients aged 40 and under. Methods A retrospective analysis of patients under 40 years of age who were admitted for ACS, out of 3,859 ACS admissions in Cardiology Intensive Care Unit (CICU) in our hospital between 2012 and 2022. Results 67 patients (1.73%) were included, most of them were males (83.6%). Baseline characteristics are summarized in Table 1. 77.6% had hypertension (HTA), 22.4% had diabetes (DM) and 34.3% had dyslipidemia (DLP). 79.1% were smokers, 9.1% had a history of alcoholism and 29.9% were cocaine users. None of them had a history of stroke, atrial fibrillation (AF). Only 3% had ischemic heart disease. 68.7% of them were ST-elevation myocardial infarction (STEMI) and inferior STEMI was the most common (38.7%). In anterior STEMI (22 patients), 15 had a severe lesion in the mid-left anterior descending artery (LAD), and 6 in the left main stem (LM). Single-vessel disease was the most common (70.8%), with 3-vessel disease in 4.6%. 75.8% received percutaneous coronary intervention (PCI), and 3% underwent bypass surgery. During admission, 10.5% progressed to Killip class III-IV. The ICU mortality was 1.5%. 9% received vasoactive drugs and 4.5% were intubated. Non-invasive ventilation was used in 3% and high-flow nasal cannula oxygen therapy in 5.3%. 3% received intra-aortic balloon pump support and 1.5% underwent dialysis or ultrafiltration. 4.5% received an implantable cardioverter-defibrillator (ICD), although none of them developed bundle branch block or atrioventricular node block, nor AF. After discharge, 11.1% had recurrent ACS, and up to 5.6% underwent PCI again, with a mortality rate of 11.8%. Conclusion Approximately 2% of ACS occur in people younger than 40 years of age. Substance abuse (smoking, cocaine and alcoholism) becomes more prevalent in this group. Prevalence of comorbidities (such as diabetes and nephropathy) are lower, making them less prone to short-term heart failure. However, they are more susceptible to recurrent ischemic events. There is a high incidence of inferior STEMI and LM-STEMI. For these reasons, medicians may need to find out a substance abuse in this group and further research into other risk factors, such as coronary disease family history.Basal characteristicsClinical evolution of patients

Acute coronary syndromes in patients with cancer: Recent advances.

Coronary artery disease is presently one of the leading causes of death among cancer survivors. Due to the number of cancer survivors projected to reach 26 million by 2040 managing coronary disease in this population presents a unique challenge. Cancer patients face an elevated risk of atherosclerotic disease due to shared cardiovascular risk factors and the cardiotoxic effects of cancer therapies, predisposing them to acute coronary syndromes. Challenges in treating cancer patients presenting with acute coronary syndromes include atypical presentations, obscured symptoms, and the impact of cancer-related processes on traditional biomarkers. This review explores the complexities of acute coronary syndrome management in cancer patients, addressing challenges involved, recent advances in percutaneous strategies, pharmacology, and considerations for these high-risk individuals. This review discusses a balance between invasive vs. medical strategy, technical advances in multimodal imaging, intravascular physiology, intracoronary imaging, and evolving stent options, highlighting the need for tailored approaches in this complex patient population.

Acute coronary syndrome in a patient with gastric cancer treated by immune checkpoint inhibitor: A case report

AbstractObjectiveTo highlight the incidence and management of acute coronary syndrome (ACS) in patients with gastric cancer undergoing immune checkpoint inhibitor (ICI) therapy, emphasizing the need for early detection and intervention in this high‐risk population.Patients and methodsWe presented a case of a 71‐year‐old male patient with poorly differentiated adenocarcinoma of the gastric antrum, clinical stage cT4N2M0, phase III, with no prior history of chronic diseases or cardiovascular risk factors. The patient was treated with a combination of ICI therapy (sintilimab) and chemotherapy using the albumin‐bound paclitaxel combined with S1 regimen. Following therapy, he developed symptoms and diagnostic findings consistent with ACS, which was managed with percutaneous coronary stenting.ResultsThe patient's presentation with ACS during ICI therapy underscored the potential cardiovascular risks associated with cancer treatments, particularly in patients without traditional cardiovascular risk factors. Management involved collaboration between oncologists and cardiologists, leading to successful coronary stenting and continuation of antitumor therapy.ConclusionACS is a significant risk in patients with malignancies undergoing ICI therapy, even in those without prior cardiovascular disease. Early recognition and management of ACS in this context are crucial to enable the continuation of cancer treatment and improve patient outcomes. This case underscores the importance of interdisciplinary collaboration in managing complex patients with concurrent cancer and cardiovascular disease.

Assessment of the association of the rs12329760 polymorphism of the &lt;i&gt;TMPRSS2&lt;/i&gt; gene with acute coronary syndrome in patients with new coronavirus infection

Introduction. Cardiovascular diseases (СVD) rank first in terms of morbidity and mortality not only in the Russian Federation but throughout the world. Since the end of 2019 a pandemic of Severe Acute Respiratory Syndrome (SARS) or new coronavirus infection (NCI) has spread throughout the world, which contributed to the development and course of CVD. Therefore, genetic markers began to be considered as factors potentially influencing CVD, its development and severity. Objective: To evaluate the association of the nucleotide sequence variant rs12329760 of the TMPRSS2 gene with acute coronary syndrome in patients who have had a new coronavirus infection.Material and methods. The study included 100 patients (women – 50, men – 50) with ACS and previous NCI, who were selected on the basis of a positive PCR test for the presence of SARS-CoV-2 in the anamnesis, hospitalized at the regional vascular center No. 7 of the City Clinical Hospital No. 2 of the city of Novosibirsk. Women age was 59.5 ± 7.2 years, men age was 53.5 ± 9.3 years. The diagnosis of ACS was established according to a set of criteria proposed and established by the Russian Society of Cardiology and in accordance with the updated clinical recommendations of the Ministry of Health of the Russian Federation of 2020. Patients underwent clinical and instrumental examination, coronary angiography with possible stenting, as provided for in the standards of medical care and clinical guidelines. The nucleotide sequence variant rs12329760 of the TMPSS2 gene was determined in patients using PCR with further analysis of restriction fragment length polymorphism. The comparison group consisted of 200 patients with ACS without previous NCI (no positive PCR test, no positive antibodies).Results. Carriage of CC, СТ, TT, genotype variants of the nucleotide sequence rs12329760 of the TMPSS2 gene are not associated with an increased risk of developing ACS in patients with previous NCI. When comparing the frequencies of the rs12329760 genotypes of the TMPSS2 gene in groups with ACS with NCI and ACS without NCI, no statistically significant differences were obtained. In the group with ACS with NCI, carriage of the homozygous genotype was more common (p = 0.011).Conclusions. Variants of the nucleotide sequence rs12329760 of the TMPSS2 gene are not associated with ACS with previous NCI.

Features of Inflammatory Syndrome in Patients with COVID-19-Associated Pneumonia and Concomitant Chronic Coronary Syndrome

Introduction. The COVID-19 coronavirus disease caused by the SARS-CoV-2 virus has become an unprecedented challenge for the healthcare system and has taken a leading position among infectious diseases due to its rapid spread and development of complications in various body systems. COVID-19 has been shown to increase the long-term risk of both ischemic and nonischemic cardiovascular diseases. This underscores the need for primary prevention through measures such as vaccination and a deeper understanding of the pathophysiology linking COVID-19 to endothelial dysfunction and systemic inflammation. Patients hospitalized for coronavirus disease often have concomitant cardiometabolic disease. Cardiovascular complications are common in these patients, emphasizing the need for ongoing research to better understand these effects. The role of integral inflammatory indices in patients with coronavirus disease in the setting of chronic coronary syndromes (CCS) is unexplored.&#x0D; Aim. To identify the features of the course of chronic coronary syndromes in patients with pneumonia caused by coronavirus infection COVID-19, as well as to assess the relationship between the level of inflammatory indices and the severity of the disease.&#x0D; Materials and methods. 124 patients with COVID-19 were enrolled upon admission to the cardiology department of the Central City Clinical Hospital in Ivano-Frankivsk, the therapeutic department of the Kolomyia Central District Hospital and the therapeutic department of the Verkhovyna Hospital, 124 patients with COVID-19-associated pneumonia were selected, including 92 patients with a history of chronic coronary syndromes (CCS), including 49 patients with a history of acute myocardial infarction, 43 patients with stable angina pectoris and 32 patients without a history of CCS.&#x0D; Results of the study. The mean age of the examined patients was (66,2±7,8) years in the CCS group and (59,9±8,9) years in the non-CCS group.Among the patients with severe course, there were 36 patients (39,1%) in the CCS group and 10 patients (31,2%) in the non-CCS group. In the CCS group, 4 patients (4,3%) died, and in the non-CCS group, 2 patients (6,2%) died. The BMI in patients with CCS was (28,3 [26,2; 30,9]) kg/m2, in the group without CCS (26,66±3,59) kg/m2 and was higher in the CCS group (p=0,03). The mean number of days from the onset of symptoms to hospitalization in the CCS group was (7 [5;7] days, in the non-CCS group (7 [5;7] days). There was significant difference in the levels of inflammatory indices in the study groups after treatment, lower levels of SIRI 1,12 [0,58; 1,98] vs. 1,71 [0,74; 3,98] (p=0,04), NLR 4,22 [2,79; 5,40] vs. 5,3 [3,8; 9,56] (p=0,03), SII 936,75 [571,30; 1263,16] vs. 1198,75 [784,0; 2627,78] (p=0,008), PLR 154,75 [115,27; 208,09] vs. [124,23; 307,83] (p=0,04), AISI 253,61 [96,18; 437,47] vs.345,28 [229,48; 1040,13] (p=0,01). In the CCS group, a significant increase in the level of the LMR index (p=0,01) and a decrease in the level of CRP/L (p&lt;0,0001) were observed after treatment. According to the results of the ROC analysis, there is a significant prognostic value of the CRP/L marker for mortality in patients with COVID-19 pneumonia and concomitant CVD (AUC = 0,901; 95% CI 0,820 – 0,953; p&lt;0,0001) during hospitalization. The markers NMR, SIRI, NLR, SII, PLR, AISI, dNLR, CRP/L had a significant prognostic value for mortality when observed in the dynamics.&#x0D; Conclusions. Increased levels of inflammatory indices showed a significant value in predicting hospital mortality from COVID-19 with concomitant CCS in the dynamics but had no prognostic value during hospitalization. Patients who were discharged with recovery or improvement had lower levels of inflammatory indices in the presence of concomitant CCS in the anamnesis.

Troponin efficacy in the diagnosis of acute coronary syndrome in patients with chronic renal failure.

There is no consensus on whether cardiac troponins with high reliability values should be different diagnostic criteria for acute myocardial infarction in patients with and without renal dysfunction. Although it is often emphasized that the etiology of elevated troponin levels in chronic kidney disease (CKD) remains unclear, elevated cardiac troponin (cTnT) levels have been associated with increased subclinical cardiac damage in these patient groups. In this study, we investigated the value of cTnT value in diagnosing acute coronary syndrome in CKD patients with high clinical suspicion of acute coronary syndrome and without acute ST segment elevation on electrocardiogram. The aim was to prevent cardiac ischemia from being overlooked in CKD patients. Coronary angiography revealed vessel occlusion in 192 patients, and the mortality rate after treatment decisions was 6.7%. The first measured troponin results showed a significant difference in patients who did not survive, indicating the prognostic value of troponin levels. Troponin values were compared with cardiovascular pathologies obtained by angiography, and elevated troponin levels strongly correlated with pathologic angiography results. The conclusion highlighted that despite prognostic uncertainties, biomarkers used for acute myocardial infarction diagnosis in patients with renal insufficiency are reliable in those with renal dysfunction. Elevated cTnT levels in CKD patients are considered a clear marker of cardiac ischemia, emphasizing the need for careful consideration of troponin values in this population.

Incidence and Predictors of Acute Coronary Syndrome in Patients on Maintenance Hemodialysis: A Prospective Cohort Study.

Cardiovascular diseases are the leading cause of death among patients on hemodialysis, with approximately 40% of the cardiovascular deaths linked to acute coronary syndrome. We aimed to investigate the incidence and risk factors of acute coronary syndrome in patients undergoing hemodialysis. Patients undergoing hemodialysis were prospectively enrolled from January 2018. Data regarding hospitalization due to acute coronary syndrome were collected at 3-month intervals through December 31, 2021. Cox regression model was used to estimate the association between baseline factors and incident acute coronary syndrome during follow-up. Patients' mean age was 66 years, 48% were men, and 16% had a history of coronary artery disease at enrolment. Over a median follow-up of 1,187 days, 85 patients were hospitalized due to acute coronary syndrome. Left main or triple vessel disease was identified in 67 patients. Risk factors associated with incident acute coronary syndrome included aging, male sex, smoking, low diastolic blood pressure, and baseline comorbidities, in addition to dialysis factors including low urea clearance, central venous catheter use, and history of dialysis access dysfunction. After multivariate analysis, age, diabetes, hyperlipidemia, smoking, and frequent interventions for vascular access remained significant risk factors. A high acute coronary syndrome incidence was observed in our cohort, with traditional risk factors playing a consistent role with that in the general population. A history of frequent dialysis access dysfunction was also associated with incident acute coronary syndrome.

Vitamin D was Superior to Omega-3 as a Simvastatin Adjuvant in Improving Blood Lipids and Atherogenic Index in Type-I Dyslipidemic Rats.

Adjuvant therapy is often used to optimize the antihyperlipidemic effect of simvastatin. Omega-3 and vitamin D supplementation are recommended as adjuvant therapies to low-intensity statins. This study aimed to compare the effects of vitamin D and omega-3 as adjuvant therapy to simvastatin to improve the lipid profiles and atherogenic index of plasma (AIP) in type-I dyslipidemic rats. Thirty-six male rats were randomized and divided into six groups: healthy control, dyslipidemic rats with no treatment, and dyslipidemic rats treated with either low-dose simvastatin only or omega-3 or vitamin D at low and high doses. Dyslipidemia was induced with high-fat diets for four weeks, followed by treatment for the next two weeks. Blood samples were withdrawn before and after simvastatin treatment. In addition, aspartate transaminase (AST) and alanine transaminase (ALT) levels were analyzed to assess liver function. Administration of a high-fat diet-induced type 1 dyslipidemia and increased ALT levels (p < 0.05). Treatment with low-dose simvastatin did not significantly improve triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDLc) or non-HDLc levels. When combined with a high-dose vitamin D, simvastatin significantly reduced TG and increased HDLc levels (p < 0.05), thereby improving AIP levels. This improvement was not observed in rats treated with omega-3 or vitamin D at a lower dose. We concluded that high-dose vitamin D as an adjuvant to simvastatin therapy was superior to omega-3 in improving TG, HDL, and AIP levels. High-dose vitamin D also improved ALT levels in type-I dyslipidemic rats. This result may be translated in clinics to reduce the risk of coronary syndrome in patients with type-I dyslipidemia.

Acute coronary syndrome in patients with oncological diseases

The purpose of this work is to increase the alertness of doctors treating cancer patients due to the high risk of developing acute coronary syndrome (ACS) and understanding the pathogenetic mechanisms of the development of ACS. Antitumor therapy should be personalized and agreed upon by an interdisciplinary team with an assessment of the impact on the risk of developing ACS, especially in patients with high cardiovascular risk. Given the limited number of studies, principles for the management of cancer patients with ACS should be based on an assessment of ischemic and hemorrhagic risks.

Acute heart failure complicating acute coronary syndromes in patients admitted to Coronary Care Unit - Cardiac Center , Al-Thawra Hospital - Sanaa, Yemen

Background: Heart Failure with all its types and presentation is the end result of acute coronary syndrome. Coronary artery disease and its acute manifestations of ST-segment elevation myocardial infarction (STEMI), non-STEMI, and unstable angina are remarked as acute coronary syndromes (ACS). Yemeni patients usually present themselves to hospital late due to a lack of society awareness of the symptoms of ischemic heart disease, absence of medical insurance, poverty, lack of medical aid and intensive care units (ICU), absence of ambulance services, and long distance to the facilitated hospital with equipped ICUs. Late presentation prevents giving thrombolytic therapy or performing invasive interventions within the right time. These factors in addition to other factors may contribute to the large number of heart failure post ACS. We designed this study to study the heart failure complicating acute coronary syndrome. Results: Out of 637 patients with ACS, 294 (39%) were in heart failure complicating ACS, with a median age of 51 years. Males represent 66% (194 patients) and females 34% (100 patients). Smoking represents 36%, khat chewing 88%, hypertension 53%, dyslipidemia 31%, past history of MI 29%, and diabetes mellitus 40%. Ischemic-type chest pain represents 49% and Dyspnea as primary symptom occurred in 29% with heart failure (HF). Late presentation of more than 12 hours represents 53% (111 patients) among patients with HF complicating STEMI or LBBB MI. These patients did not receive thrombolytic therapy or primary PCI. Patients who received thrombolytic therapy represent 45% (95 patients) of patients with HF-complicating ACS. No patients received primary PCI. Conclusions: Heart failure complicating ACS is common among our patients and associated with high in-hospital death and is mainly among young patients and related to late presentation, management with non-fibrine specific thrombolytic agents (streptokinase), and lack of STEMI catheterization team for 24 hours, seven days a week.

Acute and long-term outcomes of acute coronary syndrome in patients with hematological malignancies

Abstract Background Coronary heart disease (CHD) and cancer are the leading causes of death. Treatment outcomes have improved significantly for both disease groups. In particular, patients with hematologic malignancies (HM) have an improved prognosis. However, knowledge of the interaction between acute coronary syndrome (ACS) and HM remains poor. Objective This analysis aimed to clarify how acute coronary syndrome affects the prognosis of HM patients. Results Between January 1, 2010, and December 31, 2018, 439,716 patients with ACS insured by AOK Germany were identified, of whom 2,104 (0.5%) also had HM. Myelodysplastic/myeloproliferative disorders, lymphocytic leukemias, and plasmacytomas predominated. These patients were approximately 6 years older and more likely to have had a myocardial infarction without ST-segment elevation. These patients had more concomitant cardiovascular disease and worse NYHA stage. They were less likely to receive coronary angiography and percutaneous coronary intervention (PCI), although the number of bleeding events was not significantly increased. Hospital stay was longer. All-cause mortality was increased regardless of age. After adjustment for patient risk profile, HM was associated with worse outcomes for all endpoints studied. Conclusion Survival is lower in ACS with HM, possibly due to the fact that these patients are less likely to undergo invasive diagnostics.Mortality, MACE and re-infarctionSurvival after STEMI and NSTEMI
