Final answer:
The medications demonstrated to improve long-term survival in patients with LV systolic dysfunction are Beta-blockers, ACE inhibitors, and ARBs, which work by improving heart function and reducing blood pressure.
Step-by-step explanation:
The question pertains to which medications have been shown to improve long-term survival in patients with left ventricular (LV) systolic dysfunction. The correct answer to this question is a) Beta-blockers, ACE inhibitors, ARBs, which are known to enhance survival in these patients. According to guidelines and clinical studies, these medications work by improving heart function, reducing blood pressure, and preventing further deterioration of the heart muscle. Beta-blockers decrease the heart rate and the force of contraction, thus reducing the workload on the heart. ACE inhibitors and ARBs block the effects of angiotensin II, leading to vasodilation and reduced blood pressure, which can alleviate the stress on the heart and slow the progression of heart failure.
Lifestyle changes and other medical treatments such as cholesterol-lowering medications and antiplatelet drugs like aspirin are also important, but when specifically talking about improving survival in LV systolic dysfunction, beta-blockers, ACE inhibitors, and ARBs have a strong evidence base. These medications are used to treat or improve symptoms of cardiovascular conditions including high blood pressure and heart failure.
