Insights

Percutaneous coronary intervention (PCI) improves right ventricular (RV) function in chronic coronary syndrome patients within six months. However, RV free wall longitudinal strain (RVFWLS) remains lower than controls at 12 months post-PCI.

Area of Science:

  • Cardiology
  • Echocardiography
  • Cardiac Function Assessment

Background:

  • Chronic coronary syndromes can impact cardiac function.
  • Percutaneous coronary intervention (PCI) is a common treatment for coronary artery disease.
  • Assessing right ventricular (RV) function post-PCI is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate changes in RV systolic function after PCI in patients with chronic coronary syndromes.
  • To compare RV function metrics between patients and healthy controls.
  • To assess the utility of three-dimensional speckle tracking echocardiography (3D-STE) in monitoring RV function post-PCI.

Main Methods:

  • A prospective study included 136 patients undergoing PCI for chronic coronary syndromes and 110 healthy controls.
  • Echocardiography, including conventional and 3D-STE, was performed at 1 week, 6 months, and 12 months post-PCI.
  • Key parameters measured included TAPSE, S', RVFAC, RVFWLS, RVGLS, RVSV, and RVEF.

Main Results:

  • Significant improvements in RV function parameters (TAPSE, S', RVFAC, RVGLS, RVSV, RVEF) were observed from 1 week to 6 months post-PCI.
  • While some parameters showed no significant change between 6 and 12 months, TAPSE, S', and RVFWLS continued to increase significantly.
  • At 12 months, RVFWLS remained significantly lower in patients compared to healthy controls, despite other RV function metrics showing no significant difference.

Conclusions:

  • Right ventricular systolic function significantly improves after PCI in chronic coronary syndrome patients.
  • RVFWLS remains a potential indicator of persistent RV dysfunction post-PCI.
  • 3D-STE is a valuable noninvasive tool for quantifying RV systolic function in this patient population.

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...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
