About Dr Sanjay Gupta

I'm Dr Sanjay Gupta, a Consultant Cardiologist with specialist interest in Cardiac Imaging at York Teaching Hospital in York, UK. I believe that high quality reliable jargon-free information about health should be available at no cost to everyone in the world.

The Gender Gap: Women and heart disease

As a cardiologist, I am always thinking of heart health and heart disease. More recently, I was at a raucous party and I saw a bunch of overweight middle-aged men smoking, drinking and overeating and I couldn’t help thinking of all the damage that was potentially happening in their heart arteries. What was interesting however was that there were lots of similarly overweight, smoking and overeating [...]

POTS: The 4 pillars of management

POTS stands for Postural Orthostatic Tachycardia Syndrome. This means that patients with this condition find that they feel unwell with symptoms of tremulousness, dizziness and heart palpitations when they stand up. On objective assessment,there is an exaggerated and sustained increase in heart rate (> 30 beats/ per minute in adults; >40 beats per minute in children) compared to when the pat [...]

Heart attacks in the young: The case of Siddharth Shukla

My name is Sanjay Gupta and I am a cardiologist in York.  Today’s blog is on the subject of heart attacks. As many of you have probably come to know, the whole of India is in mourning after one of its brightest TV and film stars, Siddharth Shukla, died suddenly at the age of only 40 years.  Initial reports have suggested that Siddhartha died of a massive heart attack. Here was a wonderfully athlet [...]

Sudden Cardiac Death: The case of Puneeth Raj Kumar

On 29/10/21, the Indian Film industry lost another of its young and bright stars to an unexpected cardiac arrest. Puneeth Raj Kumar was only 46 years old, was a healthy fitness enthusiast and had just finished at the gym and then started complaining of intense fatigue. Unfortunately his heart then went into a very fast but ineffective rhythm called ventricular fibrillation. As no blood was being c [...]

Vitamin C: A genuine natural treatment for AF?

Atrial fibrillation is a common heart rhythm disturbance which may impact on both quality and quantity of life.  AF can also come and go and when a patient does develop an episode of AF, they can be very symptomatic with palpitations, breathlessness, fatigue and tiredness. We also know that AF begets AF. The more AF, you get the more you will have in the future. Whilst there are many pharmaceutica [...]

Low dose Naltrexone for POTS?

One of my specialist interests is in a condition called POTS (postural Orthostatic Tachycardia Syndrome). This is a condition that affects young patients (more women than men) who struggle with severe chronic fatigue, an inability to stand up for a prolonged period of time, heart palpitations, brain fog, lack of refreshing sleep, IBS-like gut issues, fibromyalgia and chronic pain. Despite self man [...]

NOCTURNAL HYPERTENSION

The subject of high blood pressure is both confusing and hugely anxiety-provoking for patients. The unfortunate thing is that many medical practitioners also don’t quite understand blood pressure and this shows in how blood pressure is managed in modern-day medicine. What is a complex underlying process has now been simplified to a set of 2 numbers and if those 2 numbers are higher that what a bun [...]

TYPE 2 DIABETES – This medication can make you live longer!

Today’s video is on the subject of Type 2 Diabetes and an incredible set of medications that have been shown to significantly reduce the risk of heart disease, kidney disease and death in patients with type 2 Diabetes. I can guarantee that every single person watching this video will know someone who has type 2 Diabetes and i would urge would anyone with type 2 diabetes to watch this video as the [...]

Bicuspid Aortic Valve

The aortic valve is the exit valve of the heart. When the heart contracts, it forces open this one-way valve to push the blood out into the main blood vessel, the aorta, from where the blood goes to the rest of the body. If there is a problem with this valve, then the heart may not be able to pump blood out as efficiently and this will impact on how much blood is delivered to the rest of the body. [...]

Sick Sinus Syndrome

The heart is a muscle that needs an electrical current to make it contract. That electrical current is generated and conducted around the heart from an area at the top of the heart called the Sino-atrial node. The Sino-atrial node therefore is the heart’s pacemaker. The pacemaker’s job is to generate a heart rate commensurate with the physiological needs of the body at any given time. When this go [...]

HRT and the heart Good, bad or ugly?

  The arrival of menopause can be particularly distressing both mentally and physically. A number of conditions are associated with menopause. These include hot flashes, an increase in incidence of osteoporosis, alzheimer’s, vaginal atrophy and cardiovascular disease. At the beginning of the 20th century, the FDA approved an estrogen replacement medication called Premearin for the treatment o [...]

Familial AF – Understanding the genie in the bottle

AF is commonly seen in older patients with multiple comorbidities such as diabetes, high blood pressure, obesity, vascular disease and sleep apnoea. When those patients ask me why they developed AF, I tend to blame it on age, lifestyle and inflammation and say to them that maybe AF is a symptom of these underlying problems. However there is another group of patients that I see with AF. These are y [...]

Measuring inflammation: What does CRP tell us?

Most chronic disease is caused by underlying low grade chronic inflammation.  In cardiology, one of our biggest challenges in atherosclerosis (which refers to wear and tear of the blood vessels which supply our vital organs) and these blood vessels are also prone to increased wear and tear which results in progressive damage to the vessel walls and the devlopment of plaque within the vessels. This [...]

Testosterone and the Heart

Testosterone is the principal male sex hormone and we know that in general, as men get above the age of 40, testosterone levels start dropping. We also know that as men get above the age of 40, their overall cardiac risk and overall risk of mortality starts increasing. So it appears that overall cardiac risk starts going up around about the same time as testosterone levels start falling. What we s [...]

AFib and bad kidneys: A toxic combo

One of the long term consequences of chronic conditions such as diabetes, high blood pressure and even severe obesity is the development of chronic kidney disease. In fact it is estimated that the number of patients with chronic kidney disease is more than doubling every decade. What is also a major concern is that as chronic kidney disease is an exceptionally inflammatory condition, it substantia [...]

AF in the Young

Most of the AF we see occurs in older patients - usually those above the age of 60 and therefore much of what we know about AF comes from studies involving older patients. What we are however beginning to realise is that AF can occur in younger patients too and perhaps this group of patients represents a group that we do need to study and research a lot more because what we understand about the ca [...]

AF: The Silent Enemy

Patients can have AF without experiencing any symptoms whatsoever. This is termed silent AF. The problem here is that patients may be experiencing a heart rhythm disturbance which is associated with an increased risk of stroke without knowing anything about it. It is always difficult to be accurate about the prevalence of silent AF but it is estimated that 10-40% of all AF patients are asymptomati [...]

Midodrine for POTS/dysautonomia

POTS is characterised by orthostatic intolerance. This means that patients feel significantly worse when they adopt an upright posture compared to when they are lying down.  To try and find effective treatments, it is vital that we try and understand the physiology of what happens in the body when normal healthy people stand up. When we stand up, blood in our vessels tends to get sucked down into [...]
