A negative correlation was found between the prescription of beta-adrenoceptor blocking drugs, antihypertensive therapy, nitrates, calcium channel blockers and potassium channel activators, anti-fibrinolytic drugs and haemostatics, lipid-regulating drugs, and hospital admission rates for subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction (p < 0.05). Here, KCNA3 is linked to myocardial infarction.
