Arrhythmias, hypertension and the elderly: Holter evaluation

Area of Science:

• Cardiology
• Gerontology
• Hypertension Research

Background:

• Arrhythmias are common cardiac conditions influenced by various factors.
• Hypertension and age are recognized risk factors for cardiovascular diseases.
• The specific impact of hypertension and age on different types of arrhythmias requires further clarification.

Purpose of the Study:

• To investigate the independent and combined roles of age and hypertension in determining the occurrence and severity of arrhythmias.
• To analyze the relationship between hypertension, age, and cardiac parameters like heart rate and premature beats.

Main Methods:

• Utilized 24-hour Holter electrocardiography on 336 patients to assess heart rate, and the number and severity (Lown grade) of supraventricular and ventricular premature beats.
• Excluded patients with prolonged runs of atrial fibrillation or supraventricular tachycardia.
• Employed analysis of variance and multilinear regression to analyze data, stratifying patients by age and blood pressure.

Main Results:

• Hypertensive patients exhibited higher average heart rate and increased supraventricular and premature ventricular beats compared to normotensive individuals.
• The severity of premature ventricular beats was significantly higher in hypertensive patients and in older individuals.
• Mean blood pressure was independently associated with heart rate and the burden/severity of arrhythmias, while age independently correlated with the severity of premature ventricular beats.

Conclusions:

• Hypertension is a significant inducer of cardiac arrhythmias, including premature beats.
• Increasing age exacerbates the severity of premature ventricular beats.
• Both hypertension and age are independent risk factors influencing arrhythmia development and severity.
