Introduction: There are limited data on the appropriate antithrombotic therapy in patients with stable coronary artery disease (CAD) and concurrent atrial fibrillation (AF). The efficacy of using a single antiplatelet (SAP) in addition to oral anticoagulation (OAC) as compared to OAC alone remains controversial, with the earlier regimen associated with increased risk of major bleeding. Methods: A systematic electronic search of the PubMed, EMBASE and Cochrane databases was performed to identify relevant publications. Inclusion criteria were randomized controlled studies (RCTs) and observational studies comparing OAC+SAPT to OAC alone in patients with stable CAD and concurrent AF. All-cause mortality, stroke and myocardial infarction (MI) were the endpoints analyzed. We used the inverse variance method with random-effect model to calculate the hazard ratio (HR) with 95% confidence interval (CI). Statistical heterogeneity was calculated using Higgins I2 statistics. All statistical analysis was performed using RevMan Version 5.3. Results: The final analysis included two RCTs and 3 observational studies comparing OAC+SAPT versus OAC alone in patients with stable CAD and AF. There was no difference in the rate of mortality between the two treatment strategies [HR: 1.13, 95%CI: 0.88-1.46, I2= 71%] [Figure, PANEL A]. Subgroup analysis based on RCTs and observation studies reported similar results. Additionally, there was no difference in the rate of stroke [HR: 1.24, 95%CI: 0.83-1.85, I2= 0%] [Figure, PANEL B]or MI [HR: 0.57, 95%CI: 0.29-1.14, I2= 0%] [Figure, PANEL C] between the two treatment strategies Conclusion: OAC+SAPT as compared to OAC alone in patients with stable CAD and AF was associated with similar rates of all-cause mortality, stroke and MI.

Heart rate and other risk factors in outpatients with stable coronary artery disease in Latvia The aim of the study was to characterise coronary artery disease (CAD) outpatients in Latvia by risk factors (RF) including heart rate (HR), physical examination data, clinical data and treatment. Twelve practitioners had each examined and questioned 6 to 12 patients with established CAD (n = 120). The most frequent cardiovascular (CV) RF and co-morbidity were dyslipidemia (94.2%) and hypertension (78.3%), respectively. Prevalence of increased resting HR (≥70 bpm) was 35.9% and 33.6%, when measured by pulse palpation and electrocardiography, respectively. Regarding other RFs, prevalence of treated but insufficiently controlled blood pressure 140/90 mmHg, total cholesterol 1 > 5 mmol/l and triglycerides > 1.7 mmol/l was 25.8%, 30.1% and 33.3%, respectively. Aspirin, statins and angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers were used in 96.7%, 94.2% and 85.0% of cases, respectively. Beta blockers were used in 81.7% of cases. Average daily doses of most frequently used β blockers (metoprolol and bisoprolol) were 32% and 53% from target doses, respectively. In three cases β blockers were combined with ivabradin. Our results suggest that practitioners follow guidelines and consider CV prevention by treating CAD patients. Our data identified, however, unused potential for better control of increased HR by higher doses and combinations of HR-reducing agents.

AbstractAntithrombotic treatment is a key component of secondary prevention following acute coronary syndromes (ACS). Although dual antiplatelet therapy is standard therapy post-ACS, duration of treatment is the subject of ongoing debate. Prolonged dual antiplatelet therapy in high-risk patients with history of myocardial infarction reduced the risk of recurrent myocardial infarction, stroke or cardiovascular death. Similarly, in patients with stable coronary artery disease, two-thirds of whom had a history of myocardial infarction, dual antithrombotic therapy with very-low-dose rivaroxaban and aspirin also resulted in improved ischaemic outcomes. In the absence of head-to-head comparison, choosing the most appropriate treatment strategy can be challenging, particularly when it comes to balancing the risks of ischaemia and bleeding. We aim to review the evidence for currently available antithrombotic treatments and provide a practical algorithm to aid the decision-making process.

Background: To determine the indications for which statins are being prescribed Methods: Study was conducted on Patients with indications for statins presenting to cardiology OPD,Medicine OPD and Endocrinology OPD and started on statins at PGIMER, Chandigarh, within a period of 9 months. Results: In our study, out of 243 prescriptions, 55.1%(n=134) were prescribed statins for secondary prevention and 44.9%(n=109) had statins prescribed for primary prevention. Overall coronary artery disease (37.03%) was the leading indication followed by Diabetes mellitus without ASCVD(70.64%).Other indications of secondary preventionincluded newly diagnosed statin naïve patients diagnosed with stable coronary artery disease ,unstable coronary artery disease /acute coronary artery disease , ischemic cardiovascular accidentsand peripheral arterial disease .64.22 percent patients in primary prevention group were diabetics in our study . Concluded: We concluded that secondary prevention was found to the more common indication of statin prescription than primary prevention (ratio 1.22:1). Keywords: Statin, CAD, Prevention
