Men with a history of cardiovascular disease may be more at risk of facing sudden cardiac arrest during or soon after sex, a study led by an Indian-origin researcher has revealed.
Sudden cardiac arrest (SCA) is when the heart suddenly stops beating. It usually occurs without warning.
The findings showed that although the incidence of SCA is very rare, survival rates in such cases remain low.
It is because, the partners failed to immediately perform cardiopulmonary resuscitation (CPR), which could save more lives, the researchers said.
“Even though SCA during sexual activity was witnessed by a partner, bystander CPR was performed in only one-third of the cases,” said Sumeet Chugh, Associate Director at the Cedars-Sinai Heart Institute.
For the study, published in the Journal of the American College of Cardiology, the team examined records of more than 4,500 cardiac arrests over a period of 13 years in persons above 18 years.
Out of these only 34 were during or within an hour of having sex, and 32 of those were men, who were already taking drugs for heart conditions.
Patients who experienced sudden cardiac arrest related to sexual activity also had a higher rate of ventricular fibrillation/tachycardia than those who did not.
Only one-third of these SCA cases received bystander CPR. This low bystander CPR rate accounted for less than 20 per cent of patients who survived to hospital discharge, the researchers noted.
Moreover, some cases of SCA after sexual activity may also involve medications, stimulants and alcohol use, the researchers said.
“These findings highlight the importance of continued efforts to educate the public on the importance of bystander CPR for SCA, irrespective of the circumstance,” Chugh added. (IANS)
Think twice if you find alcohol the solution for keeping your body warm during winter. Medical experts caution that, apart from the common cold and cough, winter is also the time when more heart attacks occur. Every second person in the age group of 30 and above, who are already otherwise at risk, is prone to heart failure during winter, experts say.
They also say that one should not ignore irregular discomfort in chest, severe sweating, pain in the neck, arms, jaws and shoulders or shortness of breath during winter, which are major symptoms of heart failures.
According to Vanita Arora, associate director and head of Cardiac Electrophysiology Lab and Arrhythmia Services in Max Hospital, “Everyone knows winter is the cold and flu season. But most people are unaware of the fact that it is also the prime season for heart attacks.”
She said during winter, the arteries become constricted with the fall in temperature, as a result of which the heart has to put in more effort to pump the blood. “This makes the heart stress out and it leads to a heart attack,” Arora told IANS, adding: “It is more risky for those who do not have any inkling about pre-existing heart conditions.”
Arora said that people above 30 should never indulge in overdoing anything and exhausting oneself in winter. She suggested that people, and especially diabetic patients, should avoid going for a walk in the morning on extremely chilly days and should shift their walks to the late afternoon when it is still sunny.
Arora said that too much alcohol intake during winter can cause atrial fibrillation, the most common irregular heartbeat problem called arrhythmia. In this, people tend to suffer from palpitations, fainting, chest pain or congestive heart failure.
Heart experts said that a constant check on cardiovascular risk factors is one way to ensure that the winter season doesn’t harm one’s health. People should avoid overeating during winter and should rather eat in small quantities at regular intervals, experts suggest.
Neeraj Bhalla, senior consultant in cardiology at the B.L. Kapoor Memorial Hospital, said that as the blood’s viscosity increases with the drop in temperature, heart attacks and other coronary artery diseases increase during winter.
“Cholesterol levels fluctuate significantly with the change in season, which may leave people with
borderline high cholesterol with greater cardiovascular risk during the winter months. Apart from managing cholesterol levels, it is crucial that we keep small things in mind and do not stress the heart”, Bhalla said.
People staying in places where the seasons change very frequently are more prone to heart failures in comparison to those living in cold countries. Heart failure leads to most deaths in hypothermia – a condition in which the core temperature drops below the temperature for normal metabolism. Bhalla said to keep hypothermia at bay, it is advisable to cover yourself with layers of warm clothes. Besides this, it is advisable to take a bath only with warm water.
Chandan Kedawat, senior consultant cardiology at the Pushpawati Singhania Research Institute, said: “In cold weather, the heart demands more oxygen because it is working harder.” Studies have shown that heart attacks and complications related to heart disease occur more frequently in the morning hours.
Research suggests that the early-morning rise in blood pressure or “a.m. surge” that occurs in most people may dramatically increase the risk of a heart attack or stroke. “In the winter, people tend to exert themselves or do more work in the morning because it gets dark earlier,” Kedawat said.
“This shift of activities to morning hours adds to the normal circadian variation (cardiac variations that recur every 24 hours) in the mornings – further increasing the heart rate, blood pressure and the hormones that lower the threshold for a cardiovascular event,” he explained. He advises that the best way to prevent such situations for people above 30 is to go for an alternate day check up to the doctors. IANS
