Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies01:22

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

83
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

138
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Acute Coronary Syndrome III: Diagnostic Studies

31
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...

Electrocardiogram01:29

Electrocardiogram

3.3K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Imaging Studies for Cardiovascular System V: CT

80
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

58
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Area of Science:

  • Cardiovascular Medicine
  • Hematology
  • Biomedical Engineering

Background:

  • Thromboelastography (TEG) assesses blood coagulation and predicts outcomes in cardiovascular diseases (CVD).
  • Understanding TEG's role in CVD is crucial for risk stratification and management.

Purpose of the Study:

  • To investigate the association between TEG parameters and the presence of CVD.
  • Specifically examining the relationship between TEG and coronary heart disease (CHD) and ischemic stroke.

Main Methods:

  • A single-center case-control study utilizing TEG data from 2015-2019.
  • Propensity score matching (nearest-neighbor Mahalanobis) was employed to balance covariates between CVD patients and controls.
  • Logistic regression analyses assessed the relationship between TEG and CVD, with subgroup and sensitivity analyses confirming robustness.

Main Results:

  • After matching, 151 participants (83 with CVD) were analyzed.
  • Coronary heart disease (CHD) patients exhibited significantly higher maximum amplitude (MA) compared to controls (P=0.02).
  • Multivariable analysis confirmed MA as an independent predictor of CHD (OR 1.11, P=0.04).

Conclusions:

  • Maximum Amplitude (MA) measured by TEG is significantly associated with coronary heart disease (CHD).
  • Elevated MA, potentially indicating enhanced platelet reactivity, may be linked to increased CHD risk.
  • Further large-scale prospective studies are needed to validate MA's role in CHD risk assessment.
