Fatal heart attacks: Are doctors missing the subtle symptoms?

Of the 135,950 patients who died from heart attack, around half died without a hospital admission in the prior four weeks, and around half died within four weeks of having been in hospital.

Fatal heart attacks: Are doctors missing the subtle symptoms?

New Delhi: Heart attacks are known as one of the most common causes of death across the world. Medical professionals the world over, have always emphasized the subtle signs that can lead to a heart attack, like chest pain, fainting, shortness of breath, cold sweats, etc.

These signs translating into a heart attack may occur up to a month before death, but if the results of a study are anything to go by, doctors themselves seem to overlook the symptoms.

The new UK study found that these symptoms that may look like minor, everyday problems, are often missed by doctors in many hospitalised patients.

Researchers from Imperial College London said more research is urgently needed to establish whether it is possible to predict the risk of fatal heart attacks in patients for whom this condition was not recorded as the main reason for hospital admission.

A heart attack occurs when there is a blockage of the coronary arteries. This is often caused by a blood clot. Such a blockage, if not quickly resolved, can cause parts of heart muscle to die.

Symptoms may include sudden chest pain or a 'crushing' sensation that might spread down either arm. Patients might also experience nausea or shortness of breath, along with coughing, wheezing, feeling or being sick, anxiety, light-headedness or dizziness, sweating, weakness and/or palpitations.

However, some heart attacks have more subtle symptoms and may therefore be missed or overlooked.

In the study, researchers examined records of all 446,744 NHS hospital stays in England between 2006 and 2010 that recorded heart attacks, as well as the hospitalisation history of all 135,950 heart attack deaths.

The records included whether or not patients who died of a heart attack had been admitted to hospital in the past four weeks and if so, whether signs of heart attack were recorded as the main cause of admission (primary diagnosis), additional to the main reason (secondary diagnosis), or not recorded at all.

Of the 135,950 patients who died from heart attack, around half died without a hospital admission in the prior four weeks, and around half died within four weeks of having been in hospital.

As many as 21,677 (16 per cent, or one in six) of the patients who died from heart attack had been hospitalised during the four weeks prior, but heart attack symptoms were not mentioned on their hospital records.

There are certain symptoms, such as fainting, shortness of breath and chest pain, that were apparent up to a month before death in some of these patients, researchers said.

However, doctors may not have been alert to the possibility that these signalled an upcoming fatal heart attack, possibly because there was no obvious damage to the heart at the time, he said.

These results suggest that possible signs of upcoming fatal heart attack may have been missed.

The researchers also found that of all patients admitted with a heart attack, those whose heart attack was recorded as secondary to the main condition were two to three times more likely to die than patients whose records stated heart attack as the main condition.

"Doctors are very good at treating heart attacks when they are the main cause of admission, but we don't do very well treating secondary heart attacks or at picking up subtle signs which might point to a heart attack death in the near future," said Perviz Asaria, from ICL.

The research was published in The Lancet Public Health journal.
