Cardiology Digest podcast: Episode #9

We look at high-sensitivity cardiac troponin I for risk-stratification in coronary artery disease. Next, we evaluate a possible link between heart attacks and cognitive decline. Finally, we plunge into new research about a finding in the heart that may pose a risk to divers.

Risk-classification of patients with known coronary artery disease using high-sensitivity cardiac troponin I
Cognitive repercussions of a myocardial infarction
A possible primary mechanism behind decompression illness

What are the latest cardiology studies?

Study #1

First on our list is a study from the Journal of the American College of Cardiology, exploring the potential of high-sensitivity cardiac troponin I in risk-stratifying patients with known coronary artery disease.

"Observational data is increasingly pointing towards the utility of troponin beyond acute care scenarios."

Study #2

Next, we shift our focus to the brain-heart connection. Ever wondered about the cognitive repercussions of a myocardial infarction (MI)? This study from JAMA Neurology sheds light on the potential consequences.

"We've had reason to believe cardiovascular disease might play a role in cognitive decline, but the exact pathways have remained elusive."

Study #3

Finally, we dive into decompression illness. Certain divers might want to reconsider their next dive, because a recent Annals of Internal Medicine study suggests a primary mechanism behind decompression illness that could change the way we perceive diving risks.

"After a staggering 33 500 dives, the findings were quite revealing. Decompression illness was detected in 13% of the divers. But here's the catch: all those who experienced the illness had…"
