Insights

This study found hypertrophic cardiomyopathy (HCM) affects 0.24% of Spain's working population. Among those without hypertension, the prevalence of HCM was 0.19%.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Hypertrophic cardiomyopathy (HCM) is a significant cardiac condition with unknown prevalence in Spain's general population.
  • Previous epidemiological studies on HCM in Spain are lacking, necessitating research in diverse population subsets.

Purpose of the Study:

  • To determine the prevalence of hypertrophic cardiomyopathy (HCM) within a large, working-age population sample in Spain.
  • To specifically assess HCM prevalence in individuals without a history of hypertension.

Main Methods:

  • A cohort of 13,179 Spanish workers underwent electrocardiogram (ECG) screening.
  • Individuals with abnormal ECGs or relevant medical history were referred for echocardiography.
  • Hypertrophic cardiomyopathy was defined as left ventricular parietal thickness ≥13mm.

Main Results:

  • A total of 16 cases of hypertrophic cardiomyopathy were identified, yielding an overall prevalence of 0.24%.
  • In the subgroup of workers without hypertension, 10 cases were detected, resulting in a prevalence of 0.19%.
  • Echocardiographic evaluation was completed by 496 of the 1008 workers referred.

Conclusions:

  • The estimated prevalence of hypertrophic cardiomyopathy in the studied Spanish working population is 0.24%.
  • The prevalence of HCM in the normotensive subgroup was found to be 0.19%.

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

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...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

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...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

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,...

Cardiomyopathy IV: Restrictive Cardiomyopathy01:29

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
