Insights

Masked hypertension (MH), a condition with normal office blood pressure but high out-of-office readings, poses significant cardiovascular risks. Early detection using cardiac-ankle vascular index (CAVI) and cardiac assessments can identify at-risk individuals.

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Hypertension Research

Background:

  • Masked hypertension (MH) presents normal office blood pressure (OBP) with elevated out-of-office readings.
  • MH carries cardiovascular risks similar to sustained hypertension, yet is challenging to diagnose.
  • Emerging evidence suggests combined vascular and cardiac assessments can aid MH detection.

Purpose of the Study:

  • To review evidence on screening for masked hypertension.
  • To highlight the utility of combined vascular and cardiac assessments for MH detection.
  • To propose a screening strategy for earlier MH identification.

Main Methods:

  • Review of emerging evidence on masked hypertension screening.
  • Analysis of findings from the PAMELA study on combined vascular and cardiac assessments.
  • Evaluation of cardiac-ankle vascular index (CAVI) as a screening parameter.

Main Results:

  • Patients with elevated CAVI and left ventricular hypertrophy (LVH) or concentric remodeling showed a 2.3-fold increased risk of MH.
  • This association was particularly noted in men and was independent of age and antihypertensive treatment.
  • CAVI demonstrated advantages in screening due to measurement stability and prognostic value.

Conclusions:

  • A stepwise screening approach using CAVI followed by echocardiography may facilitate earlier MH detection in at-risk patients.
  • Timely intervention based on early MH detection can potentially reduce cardiovascular morbidity and mortality.
  • Further validation and cost-effectiveness analyses are needed for the proposed screening strategy.

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...

Coronary 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...

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,...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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)...

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...
