I would like to stress that you should only alter the dosage or stop Beta-blocker usage with the explicit consent of your usual healthcare provider as they will know about your unique clinical situation and all I am doing in this vlog is just givin [...]

Cryptogenic Stroke

It is therefore cruc [...]


Pericarditis refers to inflammation of the pericardium The pericardium is a sac within which the heart sits. This sac has 2 layers- known as the visceral and parietal layers separated by a potential space which contains about 10-50mls of fluid. Acute inflammation of this sac is known as acute pericarditis. If the inflammation spreads to the surface of the heart itself, it is termed myopericarditis [...]

The three things that can go wrong with the heart

At first glance, the subject of heart disease can seem exceptionally complex - consisting of  several different conditions, medical jargon and very scary sounding terminology. However when we really examine heart disease closely there are in general mainly 3 things that can go wrong with the heart and cause harm and if we know this then we are able to firstly understand the different conditions be [...]

The Great Medication Lottery

A lady in her 60s recently consulted me. She was extremely concerned because she was facing a dilemma and she did not know what to do. Basically she had been to see her GP and because her cholesterol was found to be a little on the higher side, she was being strongly advised by her GP to take a Statin. My patient did not want to take Statins. Her argument was that she had never had a problem with [...]

MINOCA : When a heart attack is not a heart attack

The term MINOCA stands for Myocardial infarction with non-obstructive coronary arteries. I'll try and explain this a bit better by using a case study. A 50-year-old lady was admitted to my hospital with crushing chest tightness. She had an ECG which suggested changes in keeping with a lack of blood getting to the heart. She had a blood test to measure Troponin. Troponins are enzymes released from [...]


The word arrhythmia comes from two Greek words. The first is ‘a-’ which means absence or loss and the second is ‘rhythmos’ which means rhythm. So arrhythmia literally means absence or loss of rhythm. A cardiac arrhythmia therefore means loss of cardiac rhythm. It is however used in medical practice as a description for disturbance rather than absence of heart rhythm. In that sense, the term dysrhy [...]


My name is Sanjay Gupta and in my last video, I decried the over-zealous prescription of medications which may have no or limited benefit for the patient. In this video, I wanted to explore this further with respect to Aspirin which is commonly prescribed for prevention or treatment of heart disease. This video is enigmatically entitled ‘Welcome to the primary Bank of Aspirin’. The best banks to p [...]

A potentially transformative treatment for POTS/Long COVID.

What is POTS? POTS stands for postural orthostatic tachycardia syndrome. In this condition, patients complain when they stand up for a prolonged period of time, they feel very uncomfortable with dizziness, palpitations and tremulousness and therefore they either have to sit or lie down or they risk collapsing. When you examine them, the heart rate can be found to be excessively fast.  As doctors, [...]

Resynchronising the Heart in Heart Failure

You can download this script as a Hindi translation here. Today’s vlog is on the subject of heart failure and in particular on a special type of pacemaker which can make a significant improvement to the quality of life and length of life in patients with heart failure. What is heart failure? The heart is a pump and if the heart is in some way damaged - be that by a heart attack or a virus or harmf [...]

Leaky Heart Valves

 We are blessed with 4 heart valves - 2 on the left side which are known as the mitral and aortic valves and 2 on the right side - the tricuspid and pulmonary valves. Sometimes due to a congenital problem, age related changes or even an acquired cause, these valves can start leaking and when they do so to a  severe extent, they can adversely  impact on a patient’s quality of life as well as their [...]

Heart Failure – Does Testosterone Hold the Key?

One of the reasons I wanted to start this channel was because of my frustration at how limited we were when it came to treating heart disease patients. Of course one of the reasons for this is that we simply don't know enough but another reason was that medicine as a whole has become very defensive. Offer the patient only those therapies which are recommended by clinical guidelines because that is [...]

The Management of Chronic Disease

I wanted to tell you a story about a patient who recently contacted me for advice.  This particular lady was in her 50s in a very prestigious and high powered post and completely fit and well. She was married, had a daughter in Australia and had a wonderful social life with hiking with her girlfriends. Around Xmas time in 2020, she developed a flu-like illness and after that she started noticing t [...]

What do heart tests tell us?

Broadly speaking there are 3 things that can go wrong with the heart. The heart is a pump and that pump may be faulty either due to congenital problem or an acquired problem. If the pump is in any way defective then not as much blood comes out of the heart and the body and all our vital organs will get less blood than they should and this could lead to harm. So cardiomyopathies, valve problems, my [...]

Lessons from Shane Warne’s death – A cardiologist’s perspective

As a doctor and cardiologist, I see heart attacks and death on a daily basis and after a while one gets used to it and it feels like nothing can shock anymore. However, I was completely shocked yesterday when I heard about Shane Warne’s death from a suspected heart attack. Firstly he was only 52. Secondly he was a world class athlete only a few years ago. Thirdly from the news it seems that he was [...]

York Hospital Consultant Could Have Treatment to Tackle Long Covid

The York Press A YORK heart specialist says he believes many Long Covid patients may actually have a condition called POTS - and could benefit from treatments used for patients with the syndrome. Dr Sanjay Gupta, a consultant cardiologist at York Hospital, is an expert in POTS, or postural tachycardia syndrome. The condition can leave sufferers debilitated, constantly exhausted, and sometimes unab [...]

AF and Dementia

The first thing I want to say is that unfortunately the practice of modern day medicine is largely servile to clinical guidelines. We decide how to treat a patient based on how someone else (i.e whoever wrote the guideline) tells us how to manage the patient. If we stick to the guideline, we feel that we are offering top quality care and we can defend ourselves in court. If we don't stick to the g [...]

Intracoronary Stents

Today’s video is on the subject of intracoronary stents. In this video, I will talk about what stents are, why they are used and what benefits and risks are associated with their implantation. The first thing to understand is that for most of us, as we get older, the major risk to our health will be progressive  ‘wear and tear’ in our heart arteries (coronary arteries). There are 2 problems with t [...]
