Novel treatments for cardiovascular disease prevention.

ABSTRACT: The purpose of this review is to describe novel pharmacologic and nonpharmacologic preventive therapies, as well as new strategies to improve delivery of available therapies. Cardiovascular disease (CVD) is the leading cause of death worldwide, and prevention plays a critical role in curbing the global epidemic. Despite available treatment for tobacco addiction, platelet inhibition, blood pressure, and lipid lowering for reduction of atherosclerotic disease, significant gaps in treatment of total CVD remain. We review a range of new preventive treatment options, including drugs for tobacco cessation, platelet/thrombotic inhibition, lipid- and blood pressure-lowering; nonpharmacologic options such as left atrial appendage closure devices and caloric restriction; and strategies such as fixed-dose combination drugs, laboratory screening for drug tailoring, and community-based prevention programs. CVD preventive research continues to evolve and provide clinicians and patients with novel pharmacologic and nonpharmacologic therapies, including new preventive strategies.

Project description:BackgroundWe conducted a systematic review of evidence from randomized controlled trials to answer the following research question: What are the relative effects of different classes of antihypertensive drugs in reducing the incidence of cardiovascular disease outcomes for healthy people at risk of cardiovascular disease?MethodsWe searched MEDLINE, EMBASE, AMED (up to February 2011) and CENTRAL (up to May 2009), and reference lists in recent systematic reviews. Titles and abstracts were assessed for relevance and those potentially fulfilling our inclusion criteria were then assessed in full text. Two reviewers made independent assessments at each step. We selected the following main outcomes: total mortality, myocardial infarction and stroke. We also report on angina, heart failure and incidence of diabetes. We conducted a multiple treatments meta-analysis using random-effects models. We assessed the quality of the evidence using the GRADE-instrument.ResultsWe included 25 trials. Overall, the results were mixed, with few significant differences, and with no drug-class standing out as superior across multiple outcomes. The only significant finding for total mortality based on moderate to high quality evidence was that beta-blockers (atenolol) were inferior to angiotensin receptor blockers (ARB) (relative risk (RR) 1.14; 95% credibility interval (CrI) 1.02 to 1.28). Angiotensin converting enzyme (ACE)-inhibitors came out inferior to calcium-channel blockers (CCB) regarding stroke-risk (RR 1.19; 1.03 to 1.38), but superior regarding risk of heart failure (RR 0.82; 0.69 to 0.94), both based on moderate quality evidence. Diuretics reduced the risk of myocardial infarction compared to beta-blockers (RR 0.82; 0.68 to 0.98), and lowered the risk of heart failure compared to CCB (RR 0.73; 0.62 to 0.84), beta-blockers (RR 0.73; 0.54 to 0.96), and alpha-blockers (RR 0.51; 0.40 to 0.64). The risk of diabetes increased with diuretics compared to ACE-inhibitors (RR 1.43; 1.12 to 1.83) and CCB (RR 1.27; 1.05 to 1.57).ConclusionBased on the available evidence, there seems to be little or no difference between commonly used blood pressure lowering medications for primary prevention of cardiovascular disease. Beta-blockers (atenolol) and alpha-blockers may not be first-choice drugs as they were the only drug-classes that were not significantly superior to any other, for any outcomes.

Project description:The management of low-density lipoprotein cholesterol (LDL-C) levels is a central strategy for the prevention of atherosclerotic cardiovascular disease. Current United States (2018 American Heart Association/American College of Cardiology/Multisociety) and European (2019 European Society of Cardiology/European Atherosclerosis Society) guidelines endorse statin therapy as the first-line therapy for pharmacologic LDL-C lowering. However, in clinical practice up to 30% of patients report partial or complete intolerance to statin therapy. While the nocebo effect with statins is well described, perceived statin intolerance prevents many patients from achieving LDL-C thresholds associated with clinical benefit. Bempedoic acid is a novel, oral, non-statin lipid-l owering therapy that works by inhibiting adenosine triphosphate-citrate lyase, an enzymatic reaction upstream of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the hepatic cholesterol synthesis pathway. Bempedoic acid confers reduction in LDL-C of ~18% on background statin therapy,~21% in patients with statin intolerance, and ~38% when given in fixed-dose combination with ezetimibe. The CLEAR Outcomes trial, which enrolled high-risk primary and secondary prevention patients with reported statin intolerance and LDL-C levels ≥100 mg/dL, showed that bempedoic acid compared with placebo reduced 4-component major adverse cardiovascular events (MACE) by 13% (hazard ratio 0.87, 95% confidence interval 0.79-0.96). Bempedoic acid also reduced 3-component MACE by 15%, myocardial infarction by 23% and coronary revascularization by 19%. The benefit was even greater in the primary prevention cohort (hazard ratio 0.70, 95% confidence interval 0.55-0.89) for 4-component MACE. Bempedoic acid was associated with increases in uric acid levels and cholelithiasis, but numerically fewer events of myalgia and new-onset diabetes. These findings confirm that bempedoic acid is an effective approach to reduce cardiovascular outcomes in high-risk patients with statin intolerance who require further reduction in LDL-C.

Project description:BackgroundPersons with low socioeconomic status and nonwhite persons in the United States have high rates of cardiovascular disease. The use of combination pills (also called "polypills") containing low doses of medications with proven benefits for the prevention of cardiovascular disease may be beneficial in such persons. However, few data are available regarding the use of polypill therapy in underserved communities in the United States, in which adherence to guideline-based care is generally low.MethodsWe conducted a randomized, controlled trial involving adults without cardiovascular disease. Participants were assigned to the polypill group or the usual-care group at a federally qualified community health center in Alabama. Components of the polypill were atorvastatin (at a dose of 10 mg), amlodipine (2.5 mg), losartan (25 mg), and hydrochlorothiazide (12.5 mg). The two primary outcomes were the changes from baseline in systolic blood pressure and low-density lipoprotein (LDL) cholesterol level at 12 months.ResultsThe trial enrolled 303 adults, of whom 96% were black. Three quarters of the participants had an annual income below $15,000. The mean estimated 10-year cardiovascular risk was 12.7%, the baseline blood pressure was 140/83 mm Hg, and the baseline LDL cholesterol level was 113 mg per deciliter. The monthly cost of the polypill was $26. At 12 months, adherence to the polypill regimen, as assessed on the basis of pill counts, was 86%. The mean systolic blood pressure decreased by 9 mm Hg in the polypill group, as compared with 2 mm Hg in the usual-care group (difference, -7 mm Hg; 95% confidence interval [CI], -12 to -2; P = 0.003). The mean LDL cholesterol level decreased by 15 mg per deciliter in the polypill group, as compared with 4 mg per deciliter in the usual-care group (difference, -11 mg per deciliter; 95% CI, -18 to -5; P<0.001).ConclusionsA polypill-based strategy led to greater reductions in systolic blood pressure and LDL cholesterol level than were observed with usual care in a socioeconomically vulnerable minority population.
