During the cardiac cycle, there are two important moments: systole and diastole. The first corresponds to the moment when the blood is pumped from the heart to the aortic artery, while the second refers to the moment when the blood enters the heart and there is, at the same time, the relaxation of the cardiac muscle. And it is in this second moment – diastole – that the so-called diastolic dysfunction can be detected.

To reach the conclusion about the increased risk of death, the FMUP researchers, in partnership with the Cardiology Service of the Centro Hospitalar de Vila Nova de Gaia / Espinho, analyzed the data from 19 scientific articles published over the last decade, which related the presence of diastolic dysfunction in adults and the occurrence of cardiovascular events and death, in a universe of approximately 63 thousand individuals.

“The results showed that diastolic dysfunction is associated with a 3.5-fold increase in the risk of a serious cardiovascular event, such as heart failure or acute myocardial infarction, and with a 3.1-fold increase in the risk of death for all the causes ”, explains Ricardo Ladeiras-Lopes, a researcher at FMUP and the main author of this research work.

In a statement, the researchers point out that, according to European data, the disturbance of cardiac relaxation will affect about one in three people, being more recurrent in the elderly, obese, diabetics and people with hypertension or with metabolic syndrome.

Exercise intolerance, shortness of breath and easy tiredness are some of the main symptoms of diastolic dysfunction, “although some people may be perfectly asymptomatic and not even notice anything at an early stage”, they refer.

According to Ricardo Ladeiras-Lopes, “it is essential that during the performance of the echocardiogram in the investigation of the patient with suspected cardiovascular pathology, this possible alteration is sought, so that the set of risk factors associated with the treatment can be more aggressively managed. diastolic dysfunction ”.

“Being present, it further reinforces the need to promote healthy living habits in these individuals”, underlines the cardiologist from Porto, mentioned in the statement.
