AIDr. Khaled Al-Nemer, consultant and professor of cardiology and arterial catheterization, said that patients who suffer a takotsubo heart attack—caused by emotional stress while the coronary arteries remain open—typically do not experience a recurrence, with the rate reaching up to 95%.
Al-Nemer, writing on the X platform, pointed to several theories explaining this rarity, including the intensity of emotional stress, estrogen deficiency, and specific neural pathways in the brain.
He added that a tenfold increase in troponin levels does not necessarily mean the heart attack is ten times larger, clarifying that troponin measures heart muscle injury rather than the linear size of arterial blockage.
