Summary
Hypertension patients showed better preserved diastolic function with aging compared to healthy elderly and coronary artery disease patients, despite aggressive treatment. This 12-year study highlights differences in left ventricular diastolic dysfunction progression.
Area of Science:
- Cardiology
- Geriatrics
- Internal Medicine
Background:
- Longitudinal changes in left ventricular diastolic dysfunction (LVDD) were studied over 12 years.
- Comparison groups included healthy elderly, coronary artery disease (CAD), and hypertension (HTN) patients.
Purpose of the Study:
- To compare the longitudinal changes in LVDD among healthy elderly, CAD, and HTN patients.
- To assess the impact of aging on diastolic function in these distinct patient cohorts.
Main Methods:
- A 12-year observational study (2008-2020) involving 1476 patients and 3181 echocardiograms.
- Final analysis included 130 participants with over 10 years of follow-up: 36 healthy elderly, 51 CAD, and 43 HTN.
- Echocardiographic parameters and NYHA functional class were used to assess diastolic function.
Main Results:
- Significant differences in diastolic function changes were observed between elderly vs. HTN and CAD vs. HTN groups.
- Septal and lateral E/e′ ratios, integrated score index, and NYHA functional class showed significant variations.
- Aging increased the integrated score index more in healthy elderly (0.2/year) and CAD (0.15/year) than in HTN patients (0.06/year).
Conclusions:
- Diastolic function was relatively preserved in HTN patients with aging compared to elderly and CAD subjects, even under aggressive treatment.
- Hypertension management may play a crucial role in mitigating age-related decline in diastolic function.
- The findings suggest distinct trajectories of LVDD progression based on underlying cardiovascular conditions.

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...

68
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

76
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...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

53
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...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
