Cannabis & Heart Attack Risk: New Study
- Even for young and otherwise healthy individuals, cannabis use may elevate the risk of heart attack, according to recent studies.
- The retrospective study, featured in JACC advances, revealed that cannabis users under 50 were more than six times as likely to experience a heart attack compared to non-users.
- Dr.Ibrahim Kamel, clinical instructor at Boston University Chobanian & Avedisian School of Medicine, emphasized the importance of doctors asking patients about cannabis use to evaluate their cardiovascular risk.
Startling new research reveals a link between cannabis use and an increased risk of heart attack, notably for younger adults. Multiple studies, including a retrospective analysis of over 4.6 million individuals and a meta-analysis of 12 studies, demonstrate a concerning association. Young cannabis users under 50 are at a significantly higher risk. Experts now advise doctors too closely assess cardiovascular risk,inquiring about cannabis usage.Discover the potential implications, the specific risks identified, and the expert recommendations. Stay informed with News Directory 3, as we break down the findings. Discover what’s next regarding future studies.
Cannabis Use Linked to Increased Heart Attack Risk, Studies Find
Even for young and otherwise healthy individuals, cannabis use may elevate the risk of heart attack, according to recent studies. The research, including a retrospective analysis of over 4.6 million people and a meta-analysis of 12 studies, suggests a notable association between cannabis use and cardiovascular issues.
The retrospective study, featured in JACC advances, revealed that cannabis users under 50 were more than six times as likely to experience a heart attack compared to non-users. The meta-analysis, presented at the American Collage of Cardiology’s Annual Scientific Session (ACC.25), indicated a 50% increase in heart attack risk among cannabis users.
Dr.Ibrahim Kamel, clinical instructor at Boston University Chobanian & Avedisian School of Medicine, emphasized the importance of doctors asking patients about cannabis use to evaluate their cardiovascular risk. He also suggested that consumers should be informed about the potential risks associated with cannabis use.
The retrospective study,utilizing data from TriNetX,found that cannabis users had a significantly higher risk of heart attack,ischemic stroke,heart failure,and cardiovascular death over a three-year follow-up. Participants in this study were under 50 and had no significant cardiovascular comorbidities.
The meta-analysis, pooling data from 12 studies involving over 75 million people, showed that cannabis users were 1.5 times more likely to suffer a heart attack compared to non-users. The average age of participants in these studies was 41 years.
“Asking about cannabis use should be part of clinicians’ workup to understand patients’ overall cardiovascular risk, similar to asking about smoking cigarettes,” said Dr.Ibrahim Kamel, clinical instructor at the Boston University Chobanian & Avedisian School of Medicine. “at a policy level, a fair warning should be made so that the people who are consuming cannabis know that there are risks.”
Researchers noted that inconsistencies in data prevented them from fully accounting for factors like the amount of cannabis used, or the use of othre substances like tobacco or cocaine.
“We should have some caution in interpreting the findings in that cannabis consumption is usually associated with other substances such as cocaine or other illicit drugs that are not accounted for,” Kamel said. “Patients should be forthcoming with their doctors and remember that we are their number one advocate and having the full story matters.”
The researchers believe that cannabis may impact heart rhythm, increase oxygen demand in the heart, and impair blood vessel function.one study indicated that heart attack risk peaked about an hour after cannabis consumption.
What’s next
Future prospective studies are needed to confirm these findings and identify which groups are at the greatest risk, researchers said, given the limitations of the retrospective nature of the studies and the challenges of combining data from multiple sources.
