Insights

Left ventricular hypertrophy (LVH) affects nearly a quarter of hypertension patients in Spanish clinics. The Cornell voltage-duration product (CorP) is a valuable tool for detecting LVH in general practice settings.

Area of Science:

  • Cardiology
  • Hypertension Research
  • Diagnostic Markers

Background:

  • Left ventricular hypertrophy (LVH) is a significant cardiovascular risk factor in hypertensive patients.
  • Early detection and management of LVH are crucial for reducing overall cardiovascular risk.
  • The Cornell voltage-duration product (CorP) is recognized as a reliable electrocardiogram (ECG) marker for LVH.

Purpose of the Study:

  • To determine the prevalence of LVH in patients with essential hypertension.
  • To assess the utility of the CorP method for LVH detection in a general practice setting.

Main Methods:

  • A multicenter, cross-sectional survey was conducted among outpatient hypertensive patients in Spain.
  • Left ventricular hypertrophy (LVH) was identified using the Cornell voltage-duration product (CorP) criterion (>2.440 mm.ms) on ECG.
  • ECG recordings were independently assessed to detect LVH.

Main Results:

  • The study evaluated 782 hypertensive patients with a mean age of 66.1 years; 50.6% were male.
  • Blood pressure control was inadequate in 86.8% of the study population.
  • Left ventricular hypertrophy (LVH) was detected in 23.4% of patients via the CorP method. Predictors included prior LVH, retinopathy, age, grade II hypertension, and male gender.

Conclusions:

  • Approximately one-quarter of hypertensive patients in Spanish outpatient clinics exhibit LVH, as identified by the CorP criterion.
  • The CorP method demonstrates utility for detecting LVH within general practice settings.
  • These findings underscore the importance of screening for LVH in hypertensive populations.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

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...

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...

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...

Heart 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...
