Hyderabad, July 9 (IANS) Vitamin D deficiency is not a major risk factor for heart attacks or atrial fibrillation. It is a soft target and not a hard point in management of heart disease, opines leading cardiologist Dr C. Raghu. According to him, the major risk factors for heart attacks remain hypertension, diabetes, high cholesterol and family history In an interview with IANS, the senior interventional cardiologist and clinical director at Yashoda Hospitals, Secunderabad, explained some of the recent advances in the domain of heart heath. Q: How do you look at the recent study that Vitamin D might reduce the risk of heart attacks and prevent irregular heartbeats? A: These are not therapies for these problems. These are in addition to what all other measures a person takes. People might think that Vitamin D is the only thing. Heart disease is a multi-factor disorder. Still, the standard risk factors remain diabetes, hypertension, high cholesterol and family. These have strong correlation. Vitamin D to treat or to prevent heart attack is still a long term goal even going by this study. Many studies might come on various factors and they might choose positive benefits but for these positive benefits to translate to clinical medicine is a long process. There are many medications which can definitely reduce the heart event rate but for this many factors have to be addressed properly. Vitamin D is a very soft target not a hard point. It is not the only thing. People should not think that if I take Vitamin D, I will be okay. I think fundamentals remain the same. Diabetes, hypertension, high cholesterol and physical activity continue to remain major pillars. These risk factors have to be addressed to prevent heart attack. Q: How common is atrial fibrillation in the Indian context? A: Atrial fibrillation is worsening like heart disease. It is a multifactorial disease. Most of the patients of atrial fibrillation are elderly women they have underlying hypertension, diabetes and they have stiff heart syndrome. In this group of patients prone to develop atrial fibrillation there are many hard end points which we can address rather than focusing on Vitamin D. Vitamin D is not a major risk factor. In the Indian context also, atrial fibrillation is an emerging epidemic. The main reasons are still uncontrolled high blood pressure, aging process and stiff heart. These will continue to be the main promoters of development atrial fibrillation. As a doctor, I would prefer to treat them rather than treat a very soft end point like Vitamin D. Q: Will the use of higher doses of Vitamin D for a longer period negatively impact patients? If yes, what are the risks? A: Yes. That is one of the major reasons why one should be very careful. Somebody might think what is the harm in consuming Vitamin D as it is a simple medication but that’s not the way. Unsupervised Vitamin D use for a prolonged period of time can lead to lot of medical complications. Some people might develop renal dysfunction, some people might develop hyperparathyroidism or produce more calcium (hypercalcemia). There are a lot of metabolic problems that may happen if somebody takes long duration vitamin D without proper medical supervision. Presence of deficiency of Vitamin D and its correction are not the same. Sometimes correction of vitamin D deficiency might not reduce the primary problem. Prolonged consumption of Vitamin D and unsupervised especially elderly people tend to develop more complications. One should be cautious in taking Vitamin D without supervision. Having said that, there are a lot of natural sources for production of Vitamin D. I would prefer my patients to have a natural way to produce Vitamin D by their body as a medication. I encourage my patients to have 15 minutes of sunlight at least 2-3 times a week and at least once a week, do traditional remedies like application of castor oil to promote internal development of Vitamin D. These are simple measures one can take and naturally produce Vitamin much more quantitatively better. Q-What are the other new or recent discoveries for managing heart health? A: In the management of heart health, what the recent advances suggest is to stick to the traditional risk factors only. We now have a lot of objective data. Let us consider Lipid. We have a lot of data which emerged in the last one decade indicating that people should target their Lipid. There is a lot of misinformation and misconception which are being propelled by various sources indicating that one should not believe in Lipid but we have strong data on the management of Lipid. We have clear-cut numbers. What is LDL cholesterol a person should have. The numbers are different for a person who does not have heart attack and the one who had heart attack. For a person who does not have a heart attack but has only Diabetes, we aim for LDL of less than 70. Same for a person with heart attack we aim for LDL cholesterol of less than 55. Same for a person who has got a high risk we aim for less than 35. Previously we never used to aim for such low levels of LDL cholesterol. Now we understand that a very low level of LDL cholesterol will reduce the risk of having a cardiac event. This is one of the important advances which I think people have to be aware of. There are different cut-off levels. When people go to a laboratory, the normal value of cholesterol creates confusion. They will try to remain at a much higher level than what is desired for them. A lot of personalised medicine is coming for different subsections of people. It might look very less interesting for people but it is a very important and also inexpensive way to reduce the risk of heart attack. One of the common ways to reduce heart attacks is to use aspirin. We all think that taking aspirin a day reduces the risk. Now with the availability of new data, we can understand that certain groups of patients get benefited and certain groups of patients can get harmed. What we understand is that aspirin used for patients less than 60 who have diabetes and hypertension, they get better whereas for patients who are more than 60 years, we have to select patients who are going to be benefited rather than using aspirin for all of them as a blanket. Aspirin therapy is very useful for prevention of heart stroke in people who already had a heart attack but for those people who never had a heart attack in the past or who never had bypass surgery, it is better to limit the use of aspirin among people who are less than 60. So we have to differentiate between those who had heart attack angioplasty vis-a-vis those who never had an event and use aspirin selectively for people who already had heart attack and for those who did not have heart attack, we need to calculate the risk and then only use benefit of the therapy. We now understand that women tend to have a higher risk of heart attack than what we were thinking in the past. Now a days, we see a lot of women also developing heart attacks. That is due to multiple to new risk factors which we were hitherto not knowing. These risk are enhancers: for women who tend to premature menopause naturally or surgically, they will have a higher risk of heart attack. Premature means less than 40. Women who have immunological disorders like Rheumatoid arthritis or SLE tend to have higher chances of heart attack. Such women possibly take aspirin to prevent heart attack. In addition to traditional risk factors, we have risk enhancing factors for women and people who have South Asian ancestry like Indians. They play an important role for the development of heart attacks. South Asian ancestry people tend to have higher risk of heart attack especially those with a family history of heart attacks in less than 50 years of age. Those people are at higher risk of developing heart attacks. That is also considered a risk enhancer. That’s why you see a lot of young people developing heart attacks among the Indian population because of our propensity. It is not considered as risk factor but considered risk enhancer Compared to the past we are seeing more and more women developing heart attacks at younger age. Previously we were not seeing this. Women who tend to have higher blood pressure during pregnancy may develop heart attacks. This is also considered a risk enhancer for a heart attack. Q: Is building more data helping understand the risk factors and risk enhances better? A: We continue to get data. The larger the data set, better we can understand the association. Risk scores have also been developed. These risk scores help us to estimate what is the risk of a particular person to a heart attack in the next 10 years. With these risk scores, objective risk assessment is possible compared to what we used to assess risk in a subjective way. For the Indian population who are having a risk of more than 10 per cent, it is considered high risk in India. This means more than 10 per cent chance of having a heart attack in the next 10 years is considered high risk in India. Indian race and south Asian ancestry itself is a risk enhancer. If risk calculation is more than 10 per cent, it is considered high risk whereas the same for any other race, we consider high risk if it is more than 20 per cent. The bar is set at the lower level for the Indian population. Clinical practitioners and even lay persons calculate risk score. Easiest risk score they use is by the American Heart Association. This risk score calculator is developed in the form of an app and available on Google as well as Apple store. It is an ASCVD risk calculator. This is an objective app. A person can calculate the risk. Risk score gives an idea what medication one should take. For example whether a person should take aspirin, cholesterol lowering medication, blood pressure medication, and what lifestyle modification is required. One can also know how much risk reduction is possible by adhering to those lifestyle modifications. Indians calculating risk on ASCVD need to choose an ‘other’ group which happens to be of South Asian ancestry. More than 20 per cent risk score is considered high risk in the American context while for Indian people, more than 10 per cent risk is considered high risk.

Heart failure is a common condition with no known cure. However, proper treatment can control the disease progression and thus improve a patient’s quality of life and longevity. To decide the proper course of treatment, a doctor must first determine the type of heart failure a patient has developed. Depending on the part of the heart’s pumping cycle that’s been affected, heart failure can be of two types – diastolic and systolic. You can learn more about the symptoms, causes, treatment of diastolic dysfunction and differentiation from systolic dysfunction in our previous article. In this blog, we’ll delve deeper into systolic heart failure and understand its causes and symptoms. Systolic heart failure occurs due to a problem in the heart’s contraction (or systolic) phase. It’s characterized by stretching and weakening of the left ventricular muscle, due to which the heart pumps out less oxygenated blood to the body. It’s also known as heart failure with reduced ejection infraction. As the condition worsens, it can also weaken the right ventricle and take a toll on its pumping power too. Systolic heart failure is caused by underlying medical conditions that damage the left ventricle. The most common causes include : Additionally, people who are older or have diabetes are at a higher risk of developing systolic heart failure. In systolic heart failure, an adequate amount of oxygen-rich blood doesn’t reach all organs. The most common indicator of the condition is a lower ejection fraction. It can result in the following symptoms: Typically, a doctor prescribes various tests, such as chest X-ray, ECG, and echocardiography, to diagnose systolic heart failure and its root cause. The treatment plan depends on the underlying cause. In most cases, systolic heart failure is treated using one or more of the following medications: Additionally, doctors recommend a healthy diet and lifestyle changes to improve cardiac health and manage underlying conditions, such as hypertension and diabetes. If left untreated, systolic heart failure can damage vital organs and even lead to death. It’s crucial that patients watch out for symptoms like swollen feet, mental confusion, and bluish skin color and seek medical treatment at the earliest. Dr. C Raghu is an experienced cardiologist who specializes in interventional cardiology and TAVR.

Atrial fibrillation is a progressive heart disease that can’t be cured. But the right course of treatment can help control afib symptoms and help patients live a close-to-normal life.
Atrial fibrillation (AFib) interferes with the normal functioning of the heart. It can lead to blood clots, which, in turn, can result in a stroke or heart failure. That makes it crucial to diagnose the condition early on and start the necessary treatment.
Atrial fibrillation, also known as afib or A-fib, is a medical condition that causes the heart to beat irregularly and quickly. It affects more than 3 million people in the US.
Atrial fibrillation (AFib or AF) is when your heart’s upper chambers (Atria) beat irregularly and out of sync. The heart’s pumping function isn’t as strong or efficient as it should be because the atria aren’t squeezing in rhythm as they should be.
