Association of Optimal Implementation of Sodium-Glucose Cotransporter 2 Inhibitor Therapy With Outcome for Patients With Heart Failure.

Importance: Sodium-glucose cotransporter 2 inhibitor (SGLT2-i) therapy provided incremental survival benefit to patients with heart failure and reduced ejection fraction (HFrEF) who received guideline-directed medical therapy regardless of type 2 diabetes status in a recent clinical trial. To date, estimation of the potential benefits that could be gained from optimal implementation of SGLT2-i therapy at the population level has not been quantified. Objective: To quantify the projected gains for deaths prevented or postponed with comprehensive implementation of SGLT2-i therapy for patients with HFrEF in the United States. Design, Setting, and Participants: This decision analytical model, performed from September 25 to October 20, 2019, used published sources to estimate the US population of patients with HFrEF eligible for SGLT2-i therapy and the numbers needed to treat to prevent or postpone overt death. Sensitivity analyses were performed to account for the range of potential benefits. Main Outcomes and Measures: All-cause mortality. Results: Of the 3.1 million patients with HFrEF in the United States, 2 132 800 (69%) were projected to be candidates for SGLT2-i therapy. Optimal implementation of SGLT2-i therapy was empirically estimated to prevent up to 34 125 deaths per year (range 21 840-49 140 deaths per year). A secondary analysis excluding patients on the basis of N-terminal-pro brain natriuretic peptide levels and other trial entry criteria would yield a potential benefit of 25 594 deaths per year prevented (range, 16 380-36 855 deaths per year prevented). Conclusions and Relevance: This study suggests that a substantial number of deaths in the United States could be prevented by optimal implementation of SGLT2-i therapy. These data support implementation of the current evidence into practice in a timely manner to achieve important public health benefits and to reduce the mortality burden of HFrEF.

Evolution of Omega-3 Fatty Acid Therapy and Current and Future Role in the Management of Dyslipidemia.

Omega-3 fatty acids have shown modest benefit in certain subgroups at higher cardiovascular risk. Ongoing trials are investigating cardiovascular event rate reduction with newer, more efficacious formulations with a focus on these higher risk patients. This article focuses on the previously demonstrated benefits of omega-3 fatty acid therapies, currently available formulations, and their current and future role in reducing cardiovascular risk.

Omega-3 carboxylic acids monotherapy and combination with statins in the management of dyslipidemia.

The 2013 American College of Cardiology/American Heart Association guidelines on cholesterol management placed greater emphasis on statin therapy given the well-established benefits in primary and secondary prevention of cardiovascular disease. Residual risk may remain after statin initiation, in part because of triglyceride-rich lipoprotein cholesterol. Several large trials have failed to show benefit with non-statin cholesterol-lowering medications in the reduction of cardiovascular events. Yet, subgroup analyses showed a benefit in those with hypertriglyceridemia and lower high-density lipoprotein cholesterol level, a high-risk pattern of dyslipidemia. This review discusses the benefits of omega-3 carboxylic acids, a recently approved formulation of omega-3 fatty acid with enhanced bioavailability, in the treatment of dyslipidemia both as monotherapy and combination therapy with a statin.

The Risk of Hepatotoxicity, New Onset Diabetes and Rhabdomyolysis in the Era of High-Intensity Statin Therapy: Does Statin Type Matter?

The 2013 American College of Cardiology/American Heart Association guidelines on cholesterol management have placed greater emphasis on high-intensity statin dosing for those with known cardiovascular disease or diabetes mellitus. Differences in risk of hepatotoxicity, new onset diabetes and rhabdomyolysis specifically between the high-intensity statins and the most common moderate-intensity statin, simvastatin, were not found to a significant degree in this review. Rather, baseline characteristics and drug-drug interactions (DDIs) appear to be more important regarding the risk of these adverse effects. Pharmacogenetic differences in statin metabolism may explain individual susceptibility, however genetic testing is not felt to be cost effective at this time. More importantly, statin choice should consider concomitant use of the many prevalent CYP3A4 inhibitors or inducers, and when present, rosuvastatin selection is recommended to reduce DDIs and risk of statin-induced adverse effects.
