Insights

In North India, rheumatic heart disease is the primary cause of atrial fibrillation (AF), affecting over 60% of patients. Hypertensive heart disease and COPD are also significant contributors to AF.

Area of Science:

  • Cardiology
  • Epidemiology
  • Public Health

Background:

  • Atrial fibrillation (AF) is a prevalent cardiac arrhythmia.
  • Common causes in Western countries include hypertensive heart disease, dilated cardiomyopathy, and coronary heart disease.
  • Rheumatic heart disease (RHD) remains a significant health issue in India.

Purpose of the Study:

  • To investigate the contribution of rheumatic heart disease to atrial fibrillation in North India.
  • To identify the leading causes of atrial fibrillation in a rural Indian population.

Main Methods:

  • A cohort of 137 consecutive patients diagnosed with atrial fibrillation was studied.
  • Echocardiography was performed on all patients to determine the underlying cause of AF.
  • Demographic data, including age and gender, were collected.

Main Results:

  • Rheumatic heart disease was identified as the most common cause of atrial fibrillation, accounting for 61.31% of cases (84 patients).
  • Hypertensive heart disease and chronic obstructive pulmonary disease (COPD) were the next most frequent causes, each found in 10.2% of patients (14 patients each).
  • The mean age of the patients was 51.24 years, with a higher prevalence in females (55.47%).

Conclusions:

  • Rheumatic heart disease is the predominant cause of atrial fibrillation in the studied rural North Indian population, responsible for over 60% of cases.
  • Hypertensive heart disease and COPD are the subsequent significant etiological factors for AF in this demographic.
  • Understanding regional etiological variations is crucial for targeted prevention and management strategies for atrial fibrillation.

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Dysrhythmias III: Characteristics of Dysrhythmias

Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per minute.
