Recent Heart Attack (MI)
A recent heart attack, also called a myocardial infarction, happens when a blocked coronary artery interrupts blood flow to part of the heart muscle. This causes injury or death of heart tissue.
Recent Heart Attack (MI) is grouped within the cardiovascular category.

High-Intensity Interval Training (HIIT)practicePossible
A 2026 systematic review of randomized and non-randomized human studies noted that moderate-intensity continuous training may be a safer alternative for people with unstable conditions or recent acute events, and that HIIT’s risks and benefits should be individualized. Before medical stabilization and clearance after a heart attack, maximal intervals can impose excessive cardiac workload.

Full write-up
What is it
A recent heart attack, also called a myocardial infarction, happens when a blocked coronary artery interrupts blood flow to part of the heart muscle. This causes injury or death of heart tissue. During recovery, the heart may pump less effectively and remain at increased risk for rhythm disturbances, another infarction, heart failure, and other complications. It is a serious cardiovascular condition requiring clinical care.
Evidence-backed options
The options associated with Recent Heart Attack (MI) are not interchangeable: their reported findings concern different aspects of cardiovascular recovery and risk. A finding for one outcome should not be interpreted as evidence that every consequence of a recent heart attack will change.
The reports describe Omega-3, L-Carnitine, and Vitamin C as supplements, while Glutathione was used as a short-term prophylactic infusion. Durations are not specified for the supplement reports, and the timing of any observed effects is generally not given. The Glutathione finding indicates short-term use but does not establish how long any benefit might persist.
Support is uneven across these options, and some findings come from limited clinical evidence or reviews rather than a consistent body of evidence. The reported findings also do not establish that these options replace standard care after a heart attack. Because a recent heart attack is a serious medical condition, the relevance of any option depends on individual circumstances and should be interpreted with a clinician.
What to avoid
Vitamin B7 (Biotin) is flagged because high-dose supplemental biotin can interfere with susceptible troponin assays during acute or serial cardiac biomarker evaluation. The resulting falsely low values could delay recognition or treatment of myocardial injury. This concern applies specifically when cardiac biomarkers are being used to assess a possible or recent heart attack.
Swimming places significant demand on the cardiovascular system and is contraindicated during the unstable period following a myocardial infarction until a cardiologist has provided clearance. The concern is the level of cardiovascular exertion during a vulnerable phase, rather than swimming as a permanent restriction.
Vitamin B3 (Niacin), Citrulline, and Horny Goat Weed (Epimedium) are grouped because their vasodilatory or hemodynamic effects may be difficult to tolerate during the acute period after a myocardial infarction. Niacin may contribute to hypotension or rhythm disturbances, while Citrulline and Horny Goat Weed (Epimedium) may cause blood-pressure changes or other vasodilatory effects that could compromise cardiac perfusion or destabilize susceptible patients. The relevance of these cautions depends on the acute post-infarction setting and individual cardiovascular stability. Any supplement or activity concern after a heart attack is best reviewed with the treating clinician.
