The penalty does not appear to cause clinically valid to register a death in death. Or to explain the reason for the admission of a cardiac patient to their families. And yet , every time data linking extreme sadness with heart attacks and , in general, heart diseases are more conclusive .
The latest progress of the work in this direction states that those affected by moderate to severe depression have a 40% increase in the risk of heart failure. The study was published Friday in the EuroheartCare meeting the European Society of Cardiology held in Norway. Its preparation followed over 11 years, the mental and physical state ( with data on body mass index , physical activity , smoking , blood pressure) of 63,000 of the 97,000 residents of the Norwegian Nord- Trondelag and this information was compared with the admissions and deaths due to heart failure . "We conclude that the greater the depressive symptoms , the greater the risk of heart problems ," says Lise Tuset Taste intensive care nurse responsible for the work . Less serious patients the chance of developing heart disease was only 5% higher than average.
"The evidence between depression and heart disease are becoming ever stronger ," the president of the Spanish Society of Cardiology ( SEC ), José Ramón González- Juanatey . To the extent that the main Society American cardiologists (American Heart Association) raised this past February depression add to the list of classic risk factors such as hypertension, diabetes , smoking , sedentary lifestyle or cholesterol high in patients with acute coronary syndrome ( myocardial infarction).
" Previous work had already seen the effects of depression among patients who had already suffered a heart attack or as a risk factor for coronary heart disease ," says the chairman of the SEC. But the work presented yesterday goes a step further by relating this mental illness with a larger field of cardiovascular lesions such as heart failure , the end stage of many heart disease that occurs when the heart is unable to pump blood hard enough. Its origin is very diverse , and may be linked to a heart attack, problems with heart valves or symptoms of diabetes or hypertension in patients with long evolution.
The Norwegian study also provides another interesting aspect : the direct relationship established between metabolic imbalance ( hormonal derangements in neurotransmitter ) that characterizes depression, the effects on heart health .
Much of the work published so far impinged on the indirect effects . Severe depression is identified by sadness , apathy and hopelessness of the sick. Even with the thoughts of death and suicide in severe cases . This state of mind affects the lifestyle of patients. If you have to medicate or easy it is to stop or forget them shots. They also tend to smoke more , eat worse , practice or no exercise less and gain more weight.
The study presented today support this linkage. But after neutralizing the potential effects of smoking or obesity in people tested out other direct factors linking depression and heart failure . "Depression hormone stimulates the appearance related to stress induce the onset of inflammatory processes or atherosclerosis [ deterioration of the arterial wall that may cause infarction ] ."
"It's like what happens with anger ," says González- Juanatey . The SEC Chairman recalls a recent article published in the European Journal of Cardiology which was described as an abrupt release of catecholamines ( stress hormones ) which had a direct impact on hypertension and increased platelet occurred blood increased the risk of blood clots in the vascular walls. " This increase in sympathetic tone [ nervous system ] with an increased risk of heart attack and stroke are associated ." The hormonal alteration linked to depression explain a similar phenomenon in these people, according to Gonzalez - Juanatey .
" The association between depression and cardiovascular problems observed in the clinic , with patients ," says Rafael Tabarés - Seisdedos , professor of psychiatry at the University of Valencia. This psychiatrist and member of the Centre for Biomedical Network Research on Mental Health ( Cibersam ) highlights how the Norwegian labor and other similar shows that often the presence of two or more medical problems in one person seemingly unrelated (depression and cardiac lesions this case) that , at bottom , are connected. "Whether by sharing the same physical or psychosocial factors risk , or because a pathology leads to another ," he explains . Or even when the relationship is reversed , as the Tabarés - Seisdedos own and researchers from the National Cancer Research Centre recently described in the case of cancer and Alzheimer's . "We must give adequate care response that takes into account these associations and correct the current segmentation specialties " he says.
