Warning for the common procedure that runs the risk of an ultra-dead ‘widow maker’ Heart attack

Thousands of people with the most dangerous type of heart disease can have a fatal but easy to prevent heart attack as a result of ineffective tests, experts warn.

While one of the arteries in the heart can be dangerously blocked, blockages of the left most important coronary artery (LMCA) are considered particularly deadly because it increases the risk of a major, or what is known as a ‘widow maker’, heart attack.

Reducing the left -hand charger is usually diagnosed by a doctor who inserts a thin wire – a catheter insold – by a blood vessel in the wrist or groin and in the heart.

Here doctors can check for a decrease in blood pressure, which indicates a blockade in the most critical artery of the heart.

But figures of charities suggest that thousands of patients may have missed their potentially fatal heart disease per year due to outdated guidelines for reading these test results.

Earlier, doctors were learned to look for a blood pressure ‘score’ below 0.8 in both large blood vessels of the LMCA, which deliver most of the heart muscle of blood.

However, researchers from King’s College London now say that only one low score below 0.8 threshold in one of these branches of the LMCA could be a Tell-language warning signal of the disease.

If missed by doctors and left untreated – as is the case with more than a quarter of patients with the disease – this can lead to a sudden heart attack and even death.

Although some warning signals are easy to recognize – such as serious chest pain – others are more vagient and difficult to locate

Professor Divaka Perera, senior author of the study and an expert in cardiology at KCL, said: ‘These findings are so important because they will guide doctors to accurately interpret apparently conflicting test results.

“That means that doctors can diagnose the LMCA disease correctly and consider a stent or bypass surgery or be able to conduct further investigation by the LMCA, instead of ignoring potentially important disease in a large artery of the heart,” he added.

The experts who published their findings in the magazine Circulation: cardiovascular interventionsstudied 80 patients who underwent tests on their hearts – of which 47 already had a diagnosis of the LMCA diseases.

This test – known as a coronary angiography – ensures that doctors visualize the structure and function of the heart better, help in diagnosing heart conditions and planning future treatments.

All patients presented ‘apparently conflicting results’.

This was even the case for patients who already had a confirmed diagnosis.

Researchers concluded that excluding LMCA disease because of one ‘normal’ blood pressure lecture, more than 0.8 was insufficient.

The scientists estimate that current methods could leave up to 28 percent of patients without diagnosis.

NHS data show an increase in the number of younger adults who have suffered from heart attacks in recent decade. The largest increase (95 percent) was registered in the 25-29-year-old demography, although since the number of patients is low, even small peaks can look dramatic

They explained that a patient could have one normal reading, from the left Circumflex -artery, and still have the disease.

The experts said that because this branch is larger and provides more with the heart muscle with living oxygen, it can have a greater capacity to maintain a ‘healthy’ blood supply, offering a false sign that the heart of a person is healthy.

The researchers now ask that the current guidelines are updated, so that more people are previously diagnosed and possibly save thousands of lives.

When LMCA halt disorders are caught early, a heart attack can easily be avoided by offering a patient with one of the two bypass surgery or a simple procedure in which a stent is applied to increase the limited artery.

However, the researchers acknowledged that further evidence is needed to better understand the problems, since their research concerned a relatively small number of patients.

In the meantime, they urge doctors to think twice before they are rejected as normal test results as normal and to perform in -depth investigations into blood vessels when confronted with potentially conflicting results.

Dr. Ozan Demir, an expert in cardiology and first author of the paper, added: ‘These results will encourage doctors to perform further evaluation before they discuss LMCA’s disease.

“This can include important further studies, such as the use of an ultrasound or almost infrared cameras to immediately visualize the inside of the artery.”

Senior researchers of the British Heart Foundation Welcomed the findings, as a ‘crucial step’ in preventing ‘big heart attacks’.

Professor Bryan Williams, the most important scientific and medical officer of the charity, added that although more research is needed to confirm the results, the study of doctors can help their results more accurately interpret in the future.

It is as alarming data last year that early deaths from cardiovascular problems, such as heart attacks and strokes, had affected their highest level in more than a decade.

MailOnline has previously emphasized how the number of younger than 40, in England that is being treated for heart attacks by the NHS is on the rise with rising obesity rates, and the catalog of associated health problems that are thought to be one of the most important contributing factors.

In the United Kingdom, around 420 people working age die as a result of heart conditions every week, in total an alarming 21,975 per year.

Cardiovascular disorders are the number one murderer of America and almost 1 million people die every year.
