Sleeping for seven hours a day may reduce the age of your heart as well as decrease the risks for cardiovascular disease, say researchers.

The study showed that excess heart age is the lowest in adults who sleep seven hours a night.

Sleeping times less than or greater than seven hours were associated with increased excess heart age, while short sleepers had the highest elevations in excess heart age.

Sleep duration coupled with excess heart age may prove helpful for communicating the cardiovascular risks and benefits associated with sleep duration.

“These results are important because they demonstrate a quantitative method for the inclusion of sleep duration in the establishment and communication of cardiovascular risk for individuals,” said Julia Durmer from the Emory University in Georgia, US.

The study, published in the journal Sleep, included data from 12,775 adults aged between 30-74 years.

They self reported their sleep duration which was classified into five categories — five hours or less, six, seven, eight, nine and/or more hours of sleep.

The team used sex-specific Framingham heart age algorithm to calculate each individual’s heart age and used multivariable linear or logistic regression to examine the association between sleep duration and excess heart age.

The results showed that mean adjusted excess heart age was lowest among adults who reported sleeping seven hours per 24-hour period.

“This could have utility in the clinical care of patients with cardiovascular risk, and for public health researchers interested in adding a sleep metric to future studies,” Durmer said.

According to the US-based National Sleep Foundation, people who do not sleep enough are at higher risk for cardiovascular disease and coronary heart disease-regardless of age, weight, smoking and exercise habits.

Sleeping too little causes disruptions in underlying health conditions and biological processes like glucose metabolism, blood pressure and inflammation. However, the same may hold true for over sleeping. (IANS)

Edible Marijuana May Affect Heart Health in Elderly, Says Study

A number of prior case reports, as well as epidemiological studies, have described the association between cannabis use and acute cardiovascular adverse events, including myocardial infarction, stroke, arrhythmias and sudden death

With marijuana legalisation sweeping the US, an increasing number of people believe that “weed” is the safest recreational drug, and carries health benefits that outweigh its risks.

However, according to a new study, each marijuana formulation may affect and sometimes even compromise the cardiovascular system in older adults.

“Marijuana can be a useful tool for many patients, especially for pain and nausea relief. At the same time, like all other medications, it does carry risks and side effects,” said Alexandra Saunders from the Dalhousie University in Canada.

The study, published in the Canadian Journal of Cardiology, examined the case of a patient who developed crushing chest pain and myocardial ischemia after consuming most of a marijuana lollipop.

The “inappropriate dosing and oral consumption of marijuana resulted in distress that caused a cardiac event and subsequent reduced cardiac function,” Saunders said.

The report describes a 70-year-old man with stable coronary artery disease, taking the appropriate cardiac medications, who ate most of a lollipop that was infused with 90 mg of THC (delta-9-tetrahydrocannabinol) to relieve pain and aid sleep. The lollipop caused him to have a potentially serious heart attack.

According to the report, he consumed a much larger dose than the 7 mg that is typically ingested by smoking a single joint or taking the 2.5 mg starting dose of a synthetic THC.

The patient’s ingestion of an unusually large amount of THC caused the unexpected strain on his body from anxiety and fearful hallucinations and likely triggered the cardiac event, the researchers said.

A number of prior case reports, as well as epidemiological studies, have described the association between cannabis use and acute cardiovascular adverse events, including myocardial infarction, stroke, arrhythmias and sudden death.

While previous research on marijuana-induced myocardial ischemia has mostly focused on younger patients, healthcare providers need to understand and manage cannabis use and its complications in older patients, particularly in those with cardiovascular disease, the researchers noted. (IANS)
