Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

413
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...

Pathophysiology of Cardiac Performance01:29

Pathophysiology of Cardiac Performance

624
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

1.2K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Area of Science:

  • Cardiology
  • Heart Failure Management
  • Interventional Cardiology

Background:

  • Hypertrophic cardiomyopathy (HCM) is a significant cause of morbidity, particularly advanced heart failure.
  • Despite therapeutic progress, managing advanced heart failure in HCM patients remains challenging.

Purpose of the Study:

  • To review modern therapies for hypertrophic cardiomyopathy.
  • To discuss current and developing treatment modalities for relieving obstruction in HCM.

Main Methods:

  • This narrative review presents a case study of alcohol septal ablation for hypertrophic obstructive cardiomyopathy (HOCM).
  • Discussion encompasses existing medications, surgical interventions, and procedural techniques.

Main Results:

  • Alcohol septal ablation is a viable option for HOCM.
  • The current treatment landscape includes pharmacotherapy and interventions to reduce obstruction.

Conclusions:

  • While advanced heart failure in HCM is a concern, various therapeutic strategies exist.
  • New modalities for obstruction relief in HCM are under development, offering future hope.
