Insights

Low testosterone levels in hypertensive men significantly increase the risk of major adverse cardiovascular events (MACE). Measuring total testosterone (TT) can improve cardiovascular disease risk prediction in these patients.

Area of Science:

  • Endocrinology
  • Cardiology
  • Men's Health

Background:

  • Androgen deficiency is an independent risk factor for cardiovascular events and mortality.
  • Hypertension is linked to a higher prevalence of low testosterone.
  • This study investigates low androgen levels as a predictor of cardiovascular events in hypertensive men.

Purpose of the Study:

  • To determine if low androgen concentration predicts incident major adverse cardiovascular events (MACE).
  • To assess the predictive value of total testosterone (TT) for MACE in nondiabetic hypertensive patients.

Main Methods:

  • Analysis of MACE in relation to TT using proportional hazards models.
  • Study included 228 middle-aged, nondiabetic hypertensive male patients.
  • Mean follow-up duration was 44 months.

Main Results:

  • 19 participants (8.3%) experienced a MACE.
  • Patients with MACE had lower TT (3.9±0.7ng/ml) vs. those without (4.6±1.5ng/ml).
  • Lowest TT tertile (<4.0ng/ml) showed a significantly higher risk of MACE.
  • A TT level of 5.04ng/ml had a 97.2% negative predictive value for MACE.

Conclusions:

  • Low plasma testosterone is associated with an increased risk of MACE in hypertensive patients.
  • Low endogenous androgen concentration improves cardiovascular disease risk prediction.
  • Testosterone may serve as a valuable biomarker for predicting cardiovascular risk.

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Hypertension IV: Drug Therapy and Lifestyle Modifications

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
