Insights

Three-dimensional echocardiography-derived right ventricular ejection fraction (RVEF) is a strong predictor of cardiac events in patients with ischemic and dilated cardiomyopathy. This measurement offers valuable risk stratification beyond traditional echocardiographic parameters.

Area of Science:

  • Cardiology
  • Echocardiography
  • Cardiovascular Imaging

Background:

  • Limited data exists on the prognostic significance of three-dimensional echocardiography (3DE)-derived right ventricular ejection fraction (RVEF) in ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM).
  • Assessing RV function is crucial for managing heart failure patients.

Purpose of the Study:

  • To evaluate the prognostic value of 3DE-derived RVEF in patients with ICM and DCM.
  • To determine if RVEF provides incremental prognostic information beyond conventional echocardiographic measures.

Main Methods:

  • Retrospective analysis of 120 ICM and 107 DCM patients who underwent 3DE.
  • Utilized 3DE speckle tracking software for RVEF assessment.
  • Primary endpoint: composite of cardiac death, heart failure hospitalization, myocardial infarction, or ventricular tachyarrhythmia.

Main Results:

  • RVEF was significantly associated with cardiac events in both ICM and DCM groups (Univariate and Multivariable analysis).
  • RVEF demonstrated independent prognostic value after adjusting for clinical factors and LV parameters.
  • Kaplan-Meier analysis showed significant risk stratification based on RVEF and E/e' levels.

Conclusions:

  • 3DE-derived RVEF is an independent and incremental predictor of cardiac events in ICM and DCM.
  • RVEF, combined with E/e', allows for detailed risk stratification in these patient populations.

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,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
