Prevalence, treatments and outcomes of coronary artery disease in Indians: A systematic review.

ABSTRACT:

Aim

To conduct a systematic review on the prevalence, risk factors, treatments and outcomes of Coronary Artery Disease (CAD) in Indians.

Methods and results

We conducted a systematic review of studies in Indians with CAD from Jan 1969 to Oct 2012. Initial search yielded 3885 studies and after review 288 observational studies were included. The prevalence of CAD in urban areas was 2.5%-12.6% and in rural areas, 1.4%-4.6%. The prevalence of risk factors was: smoking (8.9-40.5%), hypertension (13.1-36.9%) and diabetes mellitus (0.2-24.0%). The median time to reach hospital after an MI was 360 min. In hospital rates of drug use were: antiplatelets 68%-97.9%, beta blockers 47.3%-65.8% and ACEIs 27.8-56.8%.

Conclusions

In this first systematic review of CAD in India, prevalence of risk factors is high, treatments delayed and use of evidence based treatments variable.

Project description:BackgroundLiterature studies suggested a lower prevalence of coronary artery disease (CAD) in bicuspid aortic valve (BAV) than in tricuspid aortic valve (TAV) patients. However, this finding has been challenged. We performed a meta-analysis to assess whether aortic valve morphology has a different association with CAD, concomitant coronary artery bypass grafting (CABG), and postoperative mortality.Methods and resultsDetailed search was conducted according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline to identify all patients with BAV or TAV and presence of CAD, concomitant myocardial surgical revascularization, and the postoperative mortality. Thirty-one studies on 3017 BAV and 4586 TAV patients undergoing aortic valve surgery were included. BAV patients showed a lower prevalence of CAD (odds ratio [OR]: 0.33; 95% CI: 0.17, 0.65), concomitant CABG (OR, 0.45; 95% CI: 0.35, 0.59), and postoperative mortality (OR, 0.62; 95% CI: 0.40, 0.97) than TAV. However, BAV subjects were significantly younger than TAV (mean difference: -7.29; 95% CI: -11.17, -3.41) were more frequently males (OR, 1.61; 95% CI: 1.33, 1.94) and exhibited a lower prevalence of hypertension (OR, 0.58; 95% CI: 0.39, 0.87) and diabetes (OR, 0.71; 95% CI: 0.54, 0.93). Interestingly, a metaregression analysis showed that younger age and lower prevalence of diabetes were associated with lower prevalence of CAD (Z value: -3.03; P=0.002 and Z value: -3.10; P=0.002, respectively) and CABG (Z value: -2.69; P=0.007 and Z value: -3.36; P=0.001, respectively) documented in BAV patients.ConclusionsAnalysis of raw data suggested an association of aortic valve morphology with prevalence of CAD, concomitant CABG, and postoperative mortality. Interestingly, the differences in age and diabetes have a profound impact on prevalence of CAD between BAV and TAV. In conclusion, our meta-analysis suggests that the presence of CAD is independent of aortic valve morphology.

Project description:The concept of hybrid coronary revascularization (HCR) combines the left internal mammary artery (LIMA)-left anterior descending (LAD) graft and percutaneous coronary intervention (PCI) to non-LAD vessels. Multiple comparative studies have evaluated the safety and feasibility of HCR and coronary artery bypass grafting (CABG) for multivessel coronary artery disease (MCAD). However, the sample size of each study was small, and evidences based on single-institutional experience. The purpose of this meta-analysis was to compare the short-term outcomes of HCR with those of CABG for MCAD.PubMed, EMBASE and Cochrane Library databases, as well as conference proceedings, were searched for eligible studies published up to March 2014. We calculated summary odds ratios (OR) for primary endpoints (death, stroke; myocardial infarction (MI); target vessel revascularization (TVR); major adverse cardiac or cerebrovascular events (MACCEs)) and secondary endpoints (atrial fibrillation (AF); renal failure; length of stay in the intensive care unit (LoS in ICU); length of stay in hospital (LoS in hospital); red blood cell (RBC) transfusion). Data from 6176 participants were derived from ten cohort studies.HCR was non-inferior to CABG in terms of MACCEs during hospitalization (odds ratio (OR), 0.68, 95% confidence interval (CI), 0.34-1.33)and at one-year follow-up(0.32, 0.05-1.89) , and no significant difference was found between HCR and CABG groups in in-hospital and one-year follow-up outcomes of death, MI, stroke, the prevalence of AF and renal failure, whereas HCR was associated with a lower requirement of RBC transfusion and shorter LoS in ICU and LoS in hospital than CABG (weighted mean difference (WMD) -1.25, 95% CI, -1.62 to -0.88; -17.47, -31.01 to -3.93; -1.77, -3.07 to -0.46; respectively).Our meta-analysis indicates that HCR is feasible, safe and effective for the treatment of MCAD, with similar in-hospital and one-year follow-up outcome, significantly lower requirement of RBC transfusion, and faster recovery compared with CABG.
