Insights

Nifedipine retard and angiotensin-converting enzyme inhibitors (ACE-Is) similarly improve cardiac remodeling and function in hypertensive patients with coronary artery disease. Lowering blood pressure with either treatment offers significant benefits for left ventricular structure and function.

Area of Science:

  • Cardiology
  • Pharmacology
  • Internal Medicine

Background:

  • Antihypertensive therapy is known to reduce cardiovascular events.
  • The comparative effects of nifedipine retard and ACE inhibitors on cardiac remodeling and function remain unclear.
  • Understanding how antihypertensive treatments influence cardiac structure and function is crucial.

Purpose of the Study:

  • To compare cardiac remodeling and function changes between nifedipine retard and ACE inhibitors in hypertensive patients with coronary artery disease.
  • To investigate the influence of antihypertensive therapy on cardiac structure and function.

Main Methods:

  • Randomized trial involving 210 hypertensive patients with coronary artery disease, treated for 3 years.
  • Patients were assigned to either nifedipine retard (n=108) or ACE inhibitors (n=102).
  • Primary endpoints: changes in end-diastolic volume index (EDVI) and end-systolic volume index (ESVI). Secondary endpoints: ejection fraction (EF), stroke volume index (SVI), cardiac index (CI), and regional wall motion assessed by left ventriculography.

Main Results:

  • Both nifedipine retard and ACE inhibitors demonstrated comparable improvements in cardiac remodeling and function.
  • Significant reductions in EDVI and ESVI, alongside significant increases in EF, SVI, and CI, were observed in both groups.
  • Regional wall motion significantly improved, with weak correlations noted between blood pressure reduction and changes in cardiac parameters.

Conclusions:

  • Nifedipine retard and ACE inhibitors yield similar beneficial effects on cardiac remodeling and function.
  • Blood pressure reduction through either therapy promotes reverse remodeling and enhances cardiac function in this patient population.
  • Lowering blood pressure is critical for hypertensive patients with coronary artery disease, offering favorable effects on left ventricular structure and function.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
Antihypertensive Drugs: Angiotensin II Receptor Blockers01:30

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
