Causes of Heart Failure

Causes of Heart Failure

Causes of heart failure are difficult to analyze due to challenges in diagnosis, differences in populations & age.

Common causes ranked as per their risk factor:

  • Ischaemic Heart Disease 62%
  • Cigarette Smoking 16%
  • Hypertension (high blood pressure)10%
  • Obesity 8%
  • Diabetes 3%
  • Valvular heart disease 2% (much higher in older populations)

Rarer causes of heart failure:

  • Viral Myocarditis (an infection of the heart muscle)
  • Infiltrations of the muscle such as amyloidosis
  • HIV cardiomyopathy (caused by Human Immunodeficiency Virus)
  • Connective Tissue Diseases such as Systemic lupus erythematosus
  • Abuse of drugs such as alcohol
  • Pharmaceutical drugs such as chemotherapeutic agents
  • Pharmaceutical drugs such as chemotherapeutic agents

Obstructive Sleep Apnea, a condition of sleep disordered breathing, overlaps with obesity, hypertension and diabetes and is regarded as an independent cause of heart failure.

Signs and Symptoms

Classical symptoms of acute myocardial infarction include:

  • Sudden chest pain (typically radiating to the left arm or left side of the neck)
  • Shortness of breath
  • Nausea
  • Vomiting
  • Palpitations
  • Sweating
  • Anxiety (often described as a sense of impending doom)

Women may experience fewer typical symptoms than men, most commonly shortness of breath, weakness, a feeling of indigestion, and fatigue. Approximately one quarter of all myocardial infarctions are silent, without chest pain or other symptoms.

Heart in the Times of Corona

The present pandemic has not just been a battle against a strange unknown virus, but also a lesson in humility, for all of us. We were used to solving problems, not avoiding them. Since the path-breaking discoveries, from the late nineteenth century, humanity has overcome one challenge after another. Discovery of insulin in 1923, penicillin in 1928 and coronary angiography in 1957, bypass surgery in 1967 – all helped us climb over the hurdles. Our sense of intelligence and confidence seems to have been challenged by this little creature, that none of us had ever seen before. Read More

Remote Monitoring of Cardiac Implantable Devices

‘Cardiac Implantable Electronic Devices’ sounds rather a mouthful, doesn’t it? So, what are these devices? In simple terms, these are devices that are implanted in a person with a heart condition to enable the heart to function normally. Pacemaker, ICD, CRT-P/D and Implantable Loop Recorder are such devices that may need to be implanted in people with different heart conditions that prevent the heart from functioning normally. While these devices are often the only answer to a heart condition, they do come with a rider. You cannot go by the ‘fill it and forget it’ formula Read More
