Most athletes with diagnosed and treated genetic heart disease experienced no cardiac events

Ninety-five percent of athletes with a diagnosed and treated genetic heart disease experienced no disease-triggered cardiac events, such as cardiogenic fainting or seizures, implantable cardio-defibrillator (ICD) shocks, sudden cardiac arrest or sudden cardiac death, during an average of seven years of follow up, according to a study being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Cannabis users have higher complexity of co-existing conditions

As legislation in multiple states eases former restrictions around medical and recreational cannabis in the United States, an increasing proportion of the population reports use of the drug. Between 2016 and 2018, more than 22 percent of Massachusetts residents reported any prior cannabis use for medical or recreational reasons. However, little is known about cannabis use in patients who undergo surgery or interventional procedures, where cannabis use has important additional clinical implications.
