Now, a biomaker can aid doctors in diagnosing heart attack before symptoms appear

WASHINGTON D.C. [USA]: In a latest study, scientists have discovered a biomarker which can aid doctors in diagnosing at-risk patients before heart attack symptoms appear.

The Cedars-Sinai Medical Center study has been published in JAMA Cardiology.

Heart failure with preserved ejection fraction (HFpEF) affects many people each year. And now, thanks to the discovery of the first-ever biomarker for HFpEF, a simple blood test can reveal whether a patient's heart is not making enough of an important protein.

If the protein levels are decreased, the biomarker signal increases and physicians will be able to diagnose heart failure sooner, prescribe corrective medicines and prevent further disease progression.

Cardiac or heart failure is a clinical condition in which the heart loses the ability to eject blood to meet the requirements of the tissues of the body. Irrespective of the cause, nutritional concerns need to be addressed in this condition in order to prevent morbidity and mortality. Patients with chronic heart failure are at constant risk of losing weight due to the medical condition and also low dietary intake which is due poor appetite, depression or loss of appetite due to consumption of drugs.Dietary interventions to maintain and restore the nutritional balance are essential part of treatment therapy. These include a suitable change in calorie intake, reduction in sodium and fluid intake, maintenance of potassium and magnesium in the body, and appropriate supplementation with vitamins and minerals.Here are some simple tips by Dr Ritika Samaddar, Chief Nutritionist at Max Hospital, Saket.

"By the time heart failure symptoms develop, the critical window for corrective therapy has typically closed," said Robin Shaw, principal investigator on the study. "Our discovery allows us to not only diagnose the disease sooner, but also to treat patients before that critical period of early intervention for lifesaving care has closed."

Heart failure with preserved ejection fraction is a condition where the heart can contract, but has problems relaxing--limiting the heart's ability to fill with blood between each beat--and therefore lowers the amount of blood moving forward with each contraction.

Prior to the discovery of the biomarker, clinicians had to wait for patients to have symptoms to make a diagnosis of HFpEF and had to use an echocardiogram that measured how well the heart relaxed. There was no method to gauge the health of the heart muscle before symptoms developed or determine the severity of disease once symptoms were present.

Secret To A Happy Life

Cardiovascular heart diseases cause over a quarter of the total deaths in the country, and affect rural populations and young adults the most, according to a study published by The Lancet Global Health. The study also shows that younger adults, especially those born after 1970, have the highest death rate due to the narrowing of the heart’s arteries.

Nutritionists point out that the risk of cardiovascular diseases can be reduced through lifestyle changes. Some of them are as follows:

The biomarker--named cBIN1 Score, or CS for short--allows doctors to measure muscle deterioration and measure a protein that regulates the heart's ability to both contract and relax. As the protein decreases, CS increases, serving as an indication of onset heart failure. The CS biomarker can be measured using a simple blood draw.

The CS biomarker is designed to be used in an outpatient clinic setting. For patients with known HFpEF, doctors can draw a CS level and use it to both guide current care, including medication adjustments, and predict the chances of a patient being admitted to the hospital in the next 12 months.

"More broadly, this discovery will allow the most at-risk patients--including older patients and patients with high blood pressure, diabetes or dyslipidemia--to be checked during an annual exam from their primary care physician," said Eduardo Marbán. "This pivotal research has the potential to impact millions of people and serve as a critical tool for preventive heart care."
