Dr. Hjemdahl-Monsen studies various heart conditions, particularly focusing on spontaneous coronary artery dissection (SCAD), which can occur in otherwise healthy individuals. He investigates treatment techniques like therapeutic hypothermia, a method of lowering body temperature to protect the heart and brain during emergencies. Additionally, he evaluates the efficacy of different medical devices used after heart procedures and the effectiveness of drugs like streptokinase for patients with unstable angina and non-Q wave heart attacks.
Key findings
In a case study of a cyclist, spontaneous coronary artery dissection occurred in a healthy male after biking, adding him to the 12 previously reported cases related to physical activity.
Therapeutic hypothermia can improve blood flow and oxygen supply to the brain and heart during cardiac arrest, leading to better recovery outcomes, although more human studies are needed.
In a comparison of two vascular closure devices after heart procedures, serious complications occurred in 2.1% of patients for both devices, but the Mynx device required longer manual compression in 9.2% of cases compared to 3.7% for AngioSeal.
Streptokinase treatment in unstable angina showed minimal effectiveness, with 64% of arteries still having issues post-treatment and limited overall improvement in blood blockage measurements.
Frequently asked questions
Does Dr. Hjemdahl-Monsen study heart attacks?
Yes, Dr. Hjemdahl-Monsen researches heart attacks, including their treatment and recovery methods.
What is spontaneous coronary artery dissection?
Spontaneous coronary artery dissection (SCAD) is a rare condition where a tear forms in a coronary artery, leading to serious heart problems.
What treatments has Dr. Hjemdahl-Monsen researched?
He has researched therapeutic hypothermia, the use of drugs like streptokinase, and various devices for closing blood vessels after heart procedures.
Is Dr. Hjemdahl-Monsen's work relevant to athletes?
Yes, his research on spontaneous coronary artery dissection is particularly important for athletes and active individuals.
How does therapeutic hypothermia help stroke patients?
Therapeutic hypothermia helps by lowering the body's temperature, which can improve blood flow and oxygen supply to the brain during a stroke.

Case reports in emergency medicine
Jafri FN, Solarz D, Hjemdahl-Monsen C
Plain English This study focused on a rare condition called spontaneous coronary artery dissection (SCAD), which can lead to serious heart problems even in healthy people. Researchers described the case of a 36-year-old man who experienced a SCAD after falling from his bike, leading to symptoms like lightheadedness and chest pain. This case is significant because it adds to the understanding of SCAD, which is typically diagnosed only after fatal heart issues, with only 12 similar cases previously reported from physical activity.

Plain English The paper looks at the method of therapeutic hypothermia, which means lowering the body’s temperature to help protect the brain and heart during emergencies, like cardiac arrest. The study found that using this technique improves blood flow and oxygen supply to damaged areas, leading to better recovery outcomes, especially for people who have had a stroke or heart attack. While many animal studies show positive results, more large-scale studies on humans are needed to fully understand how it works and who benefits the most from it.
Who this helps: This helps patients who experience cardiac arrest or strokes, as well as doctors treating these conditions.
Vascular complications after percutaneous coronary intervention following hemostasis with the Mynx vascular closure device versus the AngioSeal vascular closure device.
Plain English This study looked at complications that can occur after a heart procedure in patients using two different closure devices: AngioSeal and Mynx. In a total of 428 patients, both groups had very few major issues after the procedure—2.1% experienced complications—showing no significant difference between the two devices. However, the Mynx device had a higher failure rate, as more patients needed extra manual pressure after its use compared to the AngioSeal.
Who this helps: This information benefits doctors and their patients considering which vascular closure device to use after heart procedures.
Quantitative and qualitative effects of intracoronary streptokinase in unstable angina and non-Q wave infarction.

Ambrose JA, Hjemdahl-Monsen C, Borrico S, Sherman W, Cohen M +2 more
Plain English This study looked at the use of a drug called streptokinase to treat patients with unstable angina and non-Q wave heart attacks, focusing on those whose arteries were not completely blocked. Researchers infused the drug into 36 patients and measured how well it improved blood flow in the affected arteries. They found that while 64% of arteries still had problematic lesions after treatment and there was little change in artery blockage measurements, five patients did show improvement, suggesting that streptokinase might not be very effective for most in these situations.
Who this helps: This research helps doctors understand the limited effectiveness of streptokinase for certain heart conditions, guiding treatment decisions for patients.
