Regular exercise may help people with heart disease in family

NEW YORK — Regular daily exercise may not only rev up your fitness levels, but it may also significantly cut down risk of heart diseases that could be running in your family, according to the researchers.

Greater grip strength, more physical activity and better cardiorespiratory fitness are associated with reduced risk for heart attacks and stroke — even among people with a genetic pre-disposition for heart disease, researcher said in the the findings published in the American Heart Association’s journal Circulation.

The researchers, for the study, looked at data from roughly a half-million people in the UK Biobank database. For participants with an intermediate genetic risk for cardiovascular diseases, it was revealed that those with the strongest grips were 36 per cent less likely to develop coronary heart disease and had a 46 per cent reduction in their risk for atrial fibrillation, compared to study participants with the same genetic risk who had the weakest grips.

“The main message is that being physically active is associated with a lower risk of heart disease, even if you have a high genetic risk,” said Erik Ingelsson, lead study author and Professor of Medicine at Stanford University’s School of Medicine in California.

To reach this conclusion, researchers looked at data from roughly a half-million people in the UK Biobank database.

“The main message is that being physically active is associated with a lower risk of heart disease, even if you have a high genetic risk,” said Erik Ingelsson, lead study author and Professor of Medicine at Stanford University’s School of Medicine in California.

Among individuals deemed at high genetic risk for cardiovascular diseases, high levels of cardiorespiratory fitness were associated with a 49 per cent lower risk for coronary heart disease and a 60 per cent lower risk for atrial fibrillation compared to study participants with low cardiorespiratory fitness.

“The study is not a prescription for a specific type or amount of exercise and because the results come from an observational study, Ingelsson said, adding that “we can’t definitely claim a causal connection.”

Nonetheless, the researchers said the data is robust and the results are worthy for consideration in guidelines.

Suicide can’t be predicted by asking about suicidal thoughts : Study

Most people who died of suicide deny they experience suicidal thoughts when asked by doctors in the weeks and months leading up to their death, a major Australian study has found.

The findings, co-authored by clinical psychiatrist and Professor Matthew Large from UNSW’s School of Psychiatry, Sydney that published in the journal BJPsych Open The meta-analysis challenge the widely-held assumption that psychiatrists can predict who will suicide by asking if they are preoccupied with thoughts of killing themselves.

The study showed that 80% of patients who were not undergoing psychiatric treatment and who died of suicide reported not to have suicidal thoughts when asked by their psychiatrist or GP.

“If you meet someone who has suicidal ideation there is a 98 per cent chance that they are not going to suicide,” said Professor Large, an international expert on suicide risk assessment who also works in the emergency department of a major Sydney hospital.

“But what we didn’t know was how frequently people who go on to suicide have denied having suicidal thoughts when asked directly,” he added.

“This study proves we can no longer ration psychiatric care based on the presence of suicidal thoughts alone. We need to provide high-quality, patient-centred care for everyone experiencing mental illness, whether or not they reveal they are experiencing suicidal thoughts,” Professor Large said.

About one in 10 people will have suicidal ideation in their lifetime. But the study showed suicidal ideation alone was not rational grounds for deciding who gets treatment and who does not, Professor Large said.

“We know that suicide feeling is pretty common and that suicide is actually a rare event, even among people with severe mental illness,” Professor Large added.

Suicidal ideation tells us an awful lot about how a person is feeling, their psychological distress, sometimes their diagnosis and their need for treatment but it’s not a meaningful test of future behaviour.

Suicidal feelings can fluctuate rapidly and people may suicide very impulsively after only a short period of suicidal thoughts.

But, people had good reasons not to disclose thoughts of suicide, fearing stigma, triggering over-reactions or upsetting family and friends, and being involuntarily admitted for psychiatric treatment, Professor Large said.

Professor Large emphasized that clinicians should not assume that patients experiencing mental distress without reporting suicidal ideas were not at elevated risk of suicide.
