Insights

Cardiac fibrosis, a key feature of heart disease, lacks targeted therapies. New research using advanced models reveals novel drivers and therapeutic strategies for precision antifibrotic treatments.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Stem Cell Biology

Background:

  • Cardiac fibrosis is a significant pathological feature in various cardiovascular and systemic diseases.
  • Current therapeutic strategies for cardiac fibrosis are limited, with no FDA-approved treatments directly targeting fibrotic remodeling.
  • Challenges in disease modeling and translation hinder the development of effective antifibrotic therapies.

Purpose of the Study:

  • To review emerging molecular mechanisms driving cardiac fibrosis.
  • To synthesize recent advances in experimental models for studying cardiac fibrosis.
  • To consolidate findings on preclinical and clinical investigations of antifibrotic agents.

Main Methods:

  • Analysis of recent literature on cardiac fibrosis mechanisms and therapeutic development.
  • Focus on human induced pluripotent stem cell (iPSC)-derived models, engineered heart tissues, and in vivo systems.
  • Emphasis on cross-contextual alignment of molecular drivers and therapeutic targets.

Main Results:

  • Identification of novel fibrotic drivers, including immune-stroma crosstalk, metabolic reprogramming, and mechanotransduction.
  • Advancements in experimental models offer improved fidelity for studying fibrotic processes.
  • Emerging antifibrotic agents show promise in preclinical and clinical investigations.

Conclusions:

  • New insights into fibrotic drivers are reshaping therapeutic development for cardiac fibrosis.
  • Advanced models are crucial for understanding and targeting cardiac fibrosis.
  • Cross-contextual alignment is key to developing precision antifibrotic therapies.

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

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...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

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...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
