The Captopril Challenge Test Predicts Cardiac Structure and Dysfunction in Primary Aldosteronism.

Context: The captopril challenge test (CCT) is a commonly used confirmation test that identifies the magnitude of renin- and angiotensin II-independent aldosterone production, and thus the presence and severity of primary aldosteronism (PA).

Objective: This study investigated the association between the post-CCT plasma aldosterone concentration (PAC) and cardiovascular remodeling and diastolic dysfunction.

Methods: A total of 540 PA patients with complete CCT and echocardiographic data were retrospectively analyzed.

The relationship between tissue inhibitor of metalloproteinases-1 and KCNJ5 mutation in aldosterone-producing adenoma patients.

KCNJ5 somatic mutations in aldosterone-producing adenoma (APA) are linked to higher left ventricular mass index (LVMI) and worse diastolic function. We previously identified an association between plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) and an aldosterone-induced increase in LVMI and diastolic dysfunction. This study aimed to investigate the association between the presence of KCNJ5 somatic mutation and plasma TIMP-1 in APA patients.

Lifestyle modifications and non-pharmacological management in elderly hypertension.

Many studies have examined the effectiveness of lifestyle modifications such as exercise, diet, weight loss, and stress reduction in controlling hypertension in elderly individuals, and several meta-analyses have reported that both aerobic and resistance exercise can reduce blood pressure in this population. In addition, the higher sensitivity to sodium in elderly individuals highlights the importance of restricting salt intake for blood pressure control. Low-sodium salt or potassium supplementation can help with blood pressure control in elderly individuals with hypertension.

Evaluating the effects of adrenalectomy and mineralocorticoid receptor antagonist on cardiac remodeling and diastolic function in patients with aldosterone-producing adenoma.

Cardiac remodeling and diastolic dysfunction in patients with aldosterone-producing adenomas (APA) can be improved after adrenalectomy.

The aim of this study is to evaluate the effect of MRA on cardiac remodeling and diastolic dysfunction in patients with PA.

Aldosterone, mitochondria and regulation of cardiovascular metabolic disease.

Aldosterone is a mineralocorticoid hormone involved in controlling electrolyte balance, blood pressure, and cellular signaling. It plays a pivotal role in cardiovascular and metabolic physiology. Excess aldosterone activates mineralocorticoid receptors, leading to subsequent inflammatory responses, increased oxidative stress, and tissue remodeling.

Synergistic effect of albuminuria on atherosclerosis in patients with primary aldosteronism.

Aldosteronism is associated with more severe cerebral small vessel disease in hypertensive intracerebral hemorrhage.

Primary aldosteronism is associated with various types of cardiovascular and cerebrovascular damage independently of hypertension. Although chronic hypertension and related cerebral arteriosclerosis are the main risk factors for intracerebral hemorrhage, the effects of aldosteronism remain poorly understood. We enrolled 90 survivors of hypertensive intracerebral hemorrhage, 21 of them with aldosteronism and 69 with essential hypertension as controls in this study.

How should anti-hypertensive medications be adjusted before screening for primary aldosteronism?

Anti-hypertensive medications may affect plasma renin activity and/or plasma aldosterone concentration, misleading the interpretation of the aldosterone-to-renin ratio when screening for primary aldosteronism. The Task Force of Taiwan PA recommends that, when necessary, using α-adrenergic receptor blocking agents, centrally acting α-adrenergic agonists, and/or non-dihydropyridine calcium channel blockers should be considered to control blood pressure before screening for PA. We recommend temporarily holding β-adrenergic receptor blocking agents, mineralocorticoid receptor antagonists, dihydropyridine calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and all diuretics before screening for PA.

Cardiovascular and metabolic characters of somatic mutations in primary aldosteronism.

Background: Primary aldosteronism (PA) is the leading cause of curable endocrine hypertension, which is associated with a higher risk of cardiovascular and metabolic insults compared to essential hypertension. Aldosterone-producing adenoma (APA) is a major cause of PA, which can be treated with adrenalectomy. Somatic mutations are the main pathogenesis of aldosterone overproduction in APA, of which somatic mutations are most common, especially in Asian countries.

Coronary Cameral fistula disclosed by echocardiography: a case report of typical findings and literature review.

Background: Coronary cameral fistula is a rare cardiovascular anomaly, and usually needs advanced image modalities, such as computerized tomography and/or angiography, to confirm its existence.
