Summary
Arterial stiffness (AS), measured by Cardio-Ankle Vascular Index (CAVI), impacts cardiac geometry. Improving CAVI may enhance cardiac remodeling, particularly in concentric hypertrophy.
Area of Science:
- Cardiovascular Medicine
- Biomedical Engineering
Background:
- Left ventricular hypertrophy (LVH) and diastolic dysfunction are linked to increased cardiac load from arterial stiffness (AS).
- The Cardio-Ankle Vascular Index (CAVI) is a key indicator for assessing AS, especially in Japan.
Purpose of the Study:
- To investigate the longitudinal relationship between arterial stiffness and changes in cardiac geometry.
- To identify factors influencing cardiac geometry modifications over time.
Main Methods:
- A longitudinal study involving 131 patients from 2015-2020.
- Echocardiography and CAVI measurements were taken at intervals of 401 ± 185 days.
- Multivariate analysis was used to assess the impact of CAVI changes on cardiac geometry.
Main Results:
- Changes in CAVI independently affected changes in left ventricular mass index (cardiac geometry) (B = 4.023, P = 0.046).
- Changes in CAVI also independently influenced changes in relative wall thickness (RWT) (B = 0.021, P = 0.010).
Conclusions:
- Improvements in CAVI, reflecting reduced cardiac afterload, may promote favorable cardiac remodeling.
- This suggests potential benefits for concentric remodeling and concentric hypertrophy by managing arterial stiffness.

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

01:30Peripheral Artery Disease I: Introduction
37
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

53
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
