(Reuters) – people with disease warning signs

heart, such as blood pressure and cholesterol high, there are more

placement in an institution to survive a first attack-prone to the

heart than those with better health before the heart attack

revealed a study American.

The analysis, which covered more than 500,000 people, found

that even when takes into account the age influences

and weight, few more cardiac risk factors was the

patient, children were the chances of death.

“After adjusting the age and other clinical factors, there was a

“

inverse relationship between the number of risk factors of

coronary heart disease and the realistic possibilities of

“

hospital mortality”, wrote the director of the study,

John Canto, in Journal of the American Medical Association.

“Association was consistent in several age groups and

“”

major subgroups of patients”, he added.

The researchers noted that you a possible explanation

for the result is that you people who already knew their

heart problem were medicated, Statin or

beta-blockers, who helped protect them after infarction.

The data for the analysis taken from a record

national American of almost 500,000 first strokes between

1994 and 2006. During the hospitalization, doctors indicated

If patients had some standard risk factor of

heart disease, including blood pressure, cholesterol,

diabetes, smoking, and family background.

Among all patients, more than 85 percent had to the

least one of these risk factors, and people with more of

one had heart attacks of younger, on average.

More than 50,000 patients died in the hospital.

After take into account the fact that people without

risk factors tended to be larger, and adjust the weight, the

race and gender, the study found that non-smokers without

diabetes or family history of heart disease, or

high, cholesterol or pressure were 50 percent more

likely to die in the hospital that persons with all

these signs of warning.

One in seven of those people without warning signs

died after suffering a heart attack, compared with one of

each 28 patients with all the factors of risk.

Singing and his colleagues demonstrated that patients with more

risk factors also tend to receive the medication within

of the first 24 hours of the hospital stay, or be

undergoing surgery.

Those who are warning signs would have been

early before the heart attack, or would have more regular contact

with their doctors, although there was no way of knowing that from

the data that was available, said Canto.

Is also possible that people without the factors of

traditional risk having other risks of health without measure,

that caused heart attacks and raised the possibility

of death, or that something in his bloodstream was different.
