Heart Disease: Causes, Symptoms & Prevention

Heart disease often develops silently — many people live with risk factors for years before the first warning sign appears. Chest discomfort, breathlessness, fatigue, or sudden palpitations are frequently ignored until they become serious.

Understanding why heart disease happens, how it shows early symptoms, and what you can do to prevent it is the first step toward protecting your heart health.

 

What Is Heart Disease?

Heart disease is a broad term covering conditions that affect:

  • The heart muscle
  • Blood vessels supplying the heart
  • Heart rhythm and valves

Heart disease is increasingly seen in younger adults, mainly due to lifestyle, stress, diabetes, and high blood pressure.

 

Common Causes of Heart Disease

Heart disease rarely has a single cause. It usually develops due to multiple long-term factors:

  1. High Blood Pressure (Hypertension)

Uncontrolled blood pressure strains the heart and damages arteries over time.

  1. Diabetes & High Blood Sugar

Diabetes significantly increases heart attack risk.

  1. High Cholesterol

Fatty deposits narrow blood vessels and reduce blood flow to the heart.

  1. Smoking & Shisha

Tobacco damages blood vessels and accelerates plaque buildup.

  1. Obesity & Physical Inactivity

Excess weight forces the heart to work harder and worsens other risk factors.

  1. Chronic Stress & Poor Sleep

Long working hours, stress, and irregular sleep patterns silently impact heart health.

  1. Family History

Genetics can increase risk — especially when combined with lifestyle factors.


Early Symptoms of Heart Disease (Do Not Ignore These)

Heart disease symptoms vary between individuals and may not always feel severe.

Common warning signs include:

  • Chest pain, pressure, or tightness
  • Shortness of breath (especially on exertion)
  • Unusual fatigue or weakness
  • Palpitations or irregular heartbeat
  • Dizziness or fainting
  • Swelling in legs or ankles

Important: Women and diabetic patients may experience atypical symptoms, such as fatigue or mild discomfort rather than severe chest pain.

 

When Should You See a Cardiology Clinic?

You should consult a cardiologist in Sharjah if you:

  • Have chest pain or breathlessness
  • Have diabetes, high BP, or high cholesterol
  • Have a family history of heart disease
  • Are over 35 and have never had a heart check-up
  • Experience unexplained fatigue or palpitations

Early evaluation can prevent heart attacks and long-term damage.

How Heart Disease Is Diagnosed

At a cardiology clinic, diagnosis focuses on accuracy and early detection, which may include:

  • Blood pressure & cholesterol assessment
  • ECG (electrocardiogram)
  • Echocardiography
  • Stress testing (when required)
  • Risk-factor evaluation

Not every patient needs advanced tests — ethical cardiology focuses on necessary investigations only.

 

Heart Disease Prevention: What You Can Do Today

Preventing heart disease is possible, even if you already have risk factors.

Key prevention steps:

  • Control blood pressure, sugar, and cholesterol
  • Quit smoking and reduce shisha use
  • Maintain a healthy weight
  • Exercise at least 30 minutes most days
  • Reduce salt, sugar, and processed foods
  • Manage stress and improve sleep
  • Get regular heart check-ups

Prevention is always easier — and safer — than treatment.
