Diagnosis of heart diseases and routine investigations

The different tests which can help diagnose the heart disease are:

Medical history

  • Medical history is taken to know about the present and past conditions of the patient
  • With the help of medical history, the diagnosis of heart diseases become easier
  • Medical history tells about the chief complaint of the patient and family history of the patient

Check for signs and symptoms

  • The obvious signs that are indicative of heart disease are looked for
  • This may include:
  • Swelling in legs
  • Ascites
  • Breathlessness
  • Fatigability, etc

Blood test

  • Blood tests are done to rule out any chance of  diseases that might cause heart problems such as high cholesterol, infections, etc

Chest x-ray

  • Chest x-ray may indicate collection of fluid in the lungs, which might be a result of heart disease

ECG (Electrocardiogram)

  • ECG is a diagnostic tool that assesses electrical and muscular function of the heart.
  • ECG detects the presence of any heart abnormalities that might cause heart problems


  • Echocardiogram helps in assessing heart’s systolic and diastolic function, valvular heart disease, pulmonary artery pressure and pericardial diseases in patients who are suspected for heart disease

Stress test

  • Stress test measures the health of the heart, as it responds to exertion
  • Stress test along with EKG monitors the electric functioning of the heart
  • Imaging stress test takes a picture to show the amount of blood flow in the heart
  • Abnormal results are indicative of poor health or coronary heart disease

Cardiac CT scan

  • Test done to visualize the heart’s anatomy and its circulation
  • Cardiac CT tells about the calcium or blockage in the coronary artery
  • Can be used to detect congenital heart diseases


  • MRI is done to detect heart diseases and its function 
  • Can be used to detect:
  • Pericarditis
  • Congenital heart disease
  • Coronary artery disease
  • Heart failure
  • Should be avoided in the presence of pacemaker
  • Cardiac MRI can be used to evaluate:
  • Anatomy and function of the heart and blood vessels
  • Coronary artery disease
  • Cardiac MRI can be helpful in diagnosing cardiac disease
  • Can be helpful in planning treatment plan
  • Helps in monitoring the progression

Coronary angiogram

  • Done to rule out any coronary artery diseases
  • Helps in planning future treatment plan
  • Tells about the narrowed or blocked artery

Myocardial biopsy

  • It is an invasive procedure to detect heart disease
  • Can be for detecting rejection of donor’s heart following heart transplant

 PET viability 

  • Positron Emission Tomography
  • It is used to detect the damage caused on the heart after a heart attack
  • Helps in determining further treatment plan

Thallium viability scan

  • It is used to detect the blood flow to the heart
  • Thallium scan checks for the viability of the heart muscles, the damaged heart muscles does not allow accumulation of thallium in it
