Understanding your heart health and treatment options can make every consultation more productive. Here are answers to some commonly asked questions about cardiac evaluation, symptoms, investigations and treatment.
A cardiology consultation may be appropriate when you experience symptoms such as chest discomfort, unusual breathlessness, palpitations, dizziness, fainting or reduced exercise tolerance. It may also be useful when you have cardiovascular risk factors or have been advised to undergo further cardiac evaluation by another doctor.
A cardiac consultation generally begins with a discussion of your symptoms, medical history, medications, lifestyle and relevant risk factors. The doctor may then perform a clinical examination and determine whether investigations such as an ECG, echocardiogram, blood tests or other cardiac tests are appropriate based on your individual situation.
Different cardiac investigations provide different types of information. An ECG records the electrical activity of the heart, while an echocardiogram can provide information about heart structure and function. Depending on your symptoms and clinical findings, additional tests may be recommended to understand your cardiovascular condition more completely.
Cardiovascular risk can be influenced by several factors, including high blood pressure, diabetes, high cholesterol, smoking, excess body weight, physical inactivity, family history and increasing age. Regular medical evaluation and appropriate lifestyle measures can help identify and manage cardiovascular risk according to individual needs.
Bring any previous medical reports, investigation results and a current list of medications if available. It can also be helpful to note your symptoms, when they occur and any factors that appear to make them better or worse. Sharing your relevant medical and family history can help the doctor understand your concerns and plan the next steps in your evaluation.

My seventy-five year old father underwent balloon angioplasty under the supervision of Dr. Raja Nag. Unfortunately, I was not in India at that time, but the next time I went with my dad to the doctor for his check-up and met him, I was truly impressed. In short, Dr. Raja Nag is an open-minded and knowledgeable cardiologist.Posted on Google
Samiran ParbatOne of the finest cardiologists in Kolkata. Very knowledgeable, caring, and patient-friendly. He listens carefully, explains everything clearly, and provides the right guidance. Highly recommended for anyone looking for a trusted cardiologist.Posted on Google
Jayanta HazraI have been under the care of Dr. Raja Nag for the past two years, and I could not have asked for a better doctor. He is warm and friendly, and always takes the time to speak with his patients kindly and patiently, explaining things clearly and putting me at ease at every visit. Under his treatment and the medicines he prescribed, my health has improved remarkably. I feel genuinely well and stronger than I have in a long time. Most importantly, Dr. Nag oversaw my heart stent procedure, which went very smoothly and without complication. Thanks to his skill, attention, and dependable follow-up care, I have recovered fully and am now living a healthy, active life. I am deeply grateful for his expertise and his compassion. I would recommend Dr. Raja Nag without hesitation to anyone seeking a caring and highly capable doctor.Posted on Google

Alimpan sasmalMy experience with Dr. Raja Nag has been nothing short of amazing. He has demonstrated exceptional care and professionalism throughout my father’s treatment. What truly stands out is his temperament; he remained incredibly calm and understanding of our situation, providing us with the best possible medical advice. Perhaps most importantly, he has been super responsive over calls and WhatsApp—a rare and deeply appreciated quality in such a demanding and busy profession. I am incredibly grateful to have had his kind assistance and highly recommend him to anyone seeking a compassionate and dedicated physician.Posted on Google
Ranjan Kumar ChakrabortyReally disheartened to consult a cardiologist who is short tempered … Didn’t explain general questions to patient party and is hyper and rude… never going back again…
