Summary
In hypertensive patients, coronary artery calcification (CAC) does not impact diastolic function. However, left ventricular hypertrophy is linked to impaired diastolic function in these individuals.
Area of Science:
- Cardiology
- Hypertension Research
- Diagnostic Imaging
Background:
- Essential hypertension frequently involves impaired diastolic function and increased left ventricular mass, potentially early in disease progression.
- Hypertensive patients often exhibit early signs of diastolic dysfunction and left ventricular hypertrophy.
Purpose of the Study:
- To investigate the relationship between diastolic function parameters and coronary artery calcification (CAC) in patients with hypertension.
- To explore how diastolic function and left ventricular mass are associated with CAC in hypertensive individuals.
Main Methods:
- Evaluated 128 asymptomatic hypertensive patients (58 women, 70 men) using echocardiography.
- Assessed diastolic function via E/A ratio, deceleration time, and isovolumic relaxation time.
- Classified patients based on the presence of CAC and left ventricular hypertrophy.
Main Results:
- Diastolic function parameters (E/A ratio, deceleration time, isovolumic relaxation time) did not significantly differ between patients with and without CAC.
- A significant correlation was found between the presence of CAC and increased left ventricular mass index (LVMI) (P=0.019).
- Multivariate analysis in CAC+ patients revealed inverse relationships between E/A ratio and age, blood pressure, pulse pressure, and LVMI; LVMI was the strongest determinant (R=0.26, P<0.001).
Conclusions:
- Coronary artery calcification (CAC) does not appear to directly affect diastolic function in hypertensive patients.
- Left ventricular hypertrophy is associated with impaired diastolic function in hypertensive patients, independent of CAC.
- LVMI is a significant predictor of diastolic dysfunction (E/A ratio) in hypertensive patients with CAC.

01:25Imaging 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...
01:30Coronary Artery Disease I: Introduction
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

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...
01:26Coronary 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...
01:29Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

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...
