In a recent study published in the European Heart Journal, Erik Björklund et al. found that the secondary prevention medications, such as statins and renin-angiotensin-aldosterone system (RAAS) inhibitors, and platelet inhibitors used after coronary artery bypass grafting (CABG) are essential while the use of B-blockers had no association with survival and is questionable.

A randomized, double-blinded, placebo-controlled trial which enrolled 7119 high risk  patients with coronary artery disease who had undergone recent percutaneous coronary intervention (PCI) has shown that, after 3 months of dual anti-platelet therapy (DAPT) using a P2Y12 receptor blocker (ticagrelor) and aspirin, continuing secondary prevention with a single anti-platelet therapy (SAPT) with ticagrelor alone reduces bleeding as compared to extended DAPT.

A recent study by Brian A. Ference et al. based on a UK Biobank study, published in JAMA, has shown that life-time exposure to decreased low-density lipoprotein cholesterol (LDL-C) levels and low systolic blood pressure (SBP) leads to a decreased lifetime risk of cardiovascular disease. Nonetheless, these findings do not constitute the quantified benefit of treating these risk factors in decreasing the life-time cardiovascular disease risk.

This randomized study included the data from 438, 952 individuals who were the participants of the UK Biobank study with the mean age of 65.2 years (range: 40.4 – 80.0 years) and 54.1% female participants. Participants were divided into a total of 4 groups, and 4 x 4 factorial reasoning was carried out. First participants were divided into 2 groups based on having a genetic LDL-C score being equal to or lower than, or higher than the median value. Second, they were further subdivided into 2 groups based on having their genetic systolic BP score being equal to, or lower than, or higher than the median value. The reference group further included 3 groups with each individual group having a higher LDL-C genetic score than the median, higher SBP scores than the median, and combined LDL-C and SBP genetic scores higher than the median, respectively. Differences in the plasma LDL-C, SBP, and cardiovascular event rates between the groups were compared to evaluate the correlations with the lifetime cardiovascular disease risk. The primary outcome included major coronary events which were characterized as a composite of coronary death, coronary revascularization, or nonfatal myocardial infarction. The key secondary outcomes were major cardiovascular events defined as the occurrence of a major coronary event or ischemic stroke.

When compared with the reference group, participants having LDL-C genetic scores higher than the median had 14.7-mg/dL lower LDL-C levels with an Odds ratio of 0.73 for major coronary events (95%CI: 0.70 – 0.75; P < 0.001). Participants with SBP genetic scores higher than the median had 2.9 mmHg lower SBP with an Odds ratio of 0.82 for major coronary events (95%CI: 0.79 – 0.85; P < 0.001). Finally, the participants in the group with both genetic scores higher than the median had 13.9 mg/dL lower LDL-C, 3.1 mmHg lower SBP, with an Odds ratio of 0.61 for major coronary events (95%CI: 0.59 – 0.64; P < 0.001). In a 4×4 factorial analysis, exposure to increasing genetic risk scores and lower LDL-C levels and SBP was associated with dose-dependent lower risks of major coronary events. In a meta-regression analysis, combined exposure to 38.67 mg/dL lower LDL-C and 10 mmHg lower SBP was associated with an Odds ratio of 0.22 for major coronary events (95%CI: 0.17 – 0.26; P < 0.001), and 0.32 for cardiovascular death (95%CI: 0.25 – 0.40; P < 0.001). These findings concluded the positive correlation of lifelong genetic exposure to lower LDL-C levels and lower SBP with the overall lower cardiovascular disease risk without any regard to the magnitude of benefit achieved after treating these risk factors.

There are several limitations to this study, including the lack of evaluation of risks and benefits of medications associated with lowering the LDL-C and SBP. Second, there is a lack of evidence proving that outcomes associated with naturally occurring lower LDL-C or SBP levels are the same as the outcomes associated with extrinsic drug treatment or other interventions to achieve similar plasma LDL-C or SBP levels. Hence, these study findings fail to quantify the amount of benefit gained from various treatments to lower LDL-C, SBP, or both.

Significant improvement in blood pressure control and related cardiovascular disease (CVD) risk is seen as a result of a potentially effective and pragmatic comprehensive model of care conducted as HOPE 4 trial (Heart Outcomes and Prevention Evaluation-4) presented by Dr. JD Schwalm at the European Society of Cardiology (ESC) Congress 2019 and simultaneously published in The LANCET.

According to the results of Assessment of Dual Antiplatelet Therapy Versus Rivaroxaban in Atrial Fibrillation Treated with Left Atrial Appendage Closure (ADRIFT) trial, recently presented at the European Society of Cardiology (ESC) Congress 2019 by Prof. Dr. Montalescot, from Pitié-Salpêtrière Hospital, Paris, low dose rivaroxaban is superior to dual antiplatelet therapy (DAPT) in controlling thrombin generation in patients undergoing Left Atrial Appendage Closure (LAAC).

In an original investigation done by Dr.Wen-Yi Yang and his team, the results of which got published in JAMA, concluded that raised 24-hour and nighttime blood pressure (BP) readings are linked to increased risk of death and composite cardiovascular outcomes significantly. They considered it to be an optimal way of measuring risk but noted the difference was small for the improvement in the model.

In the largest updated meta-analysis study conducted to understand the inverse association between low serum vitamin D supplementation and increased cardiovascular disease (CVD) risks, vitamin D supplementation was not associated with reduced major adverse cardiovascular events, individual CVD end points (myocardial infarction, stroke, CVD mortality) or all-cause mortality.  The findings published in the Journal of the American Medical Association Cardiology suggest vitamin D supplementation may not confer cardiovascular protection and may not be indicated for this purpose.

According to a nationwide cross-sectional study, protein biomarkers along with specific dietary patterns are linked to the development of cardiovascular disease (CVD). These findings, published in the Journal of the American Heart Association, suggest associations between dietary patterns and protein biomarkers have a role in the pathways related to inflammation, endothelial and immune function, cell adhesion and metabolism. Over the years, the role of diet in the prevention of CVD has been scientifically proven; unhealthy dietary components are important risk factors for the total global burden of this comorbidity.
