Insights

Multidetector computed tomography (MDCT) can predict future acute coronary syndrome (ACS) events in hypertensive patients. Low attenuation coronary plaques identified by MDCT are more accurate predictors than traditional risk scores.

Area of Science:

  • Cardiology
  • Radiology
  • Preventive Medicine

Background:

  • Arterial hypertension is a significant risk factor for acute coronary syndrome (ACS).
  • Multidetector computed tomography (MDCT) offers accurate, less invasive assessment of coronary atherosclerosis.
  • Evaluating MDCT's predictive capability for ACS in hypertensive individuals is crucial.

Purpose of the Study:

  • To investigate the predictive power of MDCT for future ACS events in patients with hypertension.
  • To compare MDCT's predictive accuracy against traditional cardiovascular risk parameters.

Main Methods:

  • 134 hypertensive patients underwent MDCT for coronary artery disease evaluation.
  • MDCT analysis included plaque presence, stenosis degree, and plaque characteristics.
  • Traditional parameters: Framingham risk score, carotid intima-media thickness, left ventricular mass index.

Main Results:

  • During a mean 39-month follow-up, 10 ACS events occurred (3 myocardial infarctions, 7 unstable anginas).
  • Multivariate analysis identified the total number of low attenuation plaques as an independent predictor of ACS events (p<0.001).

Conclusions:

  • Non-obstructive low attenuation coronary plaques detected by MDCT accurately predict future ACS events in hypertensive patients.
  • MDCT plaque characterization offers superior predictive accuracy compared to traditional parameters for ACS risk stratification in this population.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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

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...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Imaging Studies for Cardiovascular System V: CT

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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...
