Myocardial infarction

Each year over a million people in the U.S. have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include: -Chest discomfort - pressure, squeezing, or pain . -Shortness of breath . -Discomfort in the upper body - arms, shoulder, neck, back . -Nausea, vomiting, dizziness, lightheadedness, sweating . These symptoms can sometimes be different in women. What exactly is a heart attack? Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die. NIH: National Heart, Lung, and Blood Institute.  [from MedlinePlus]

Aspirin

The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5) [from MeSH]

Myocardial infarction

Necrosis of the myocardium caused by an obstruction of the blood supply to the heart and often associated with chest pain, shortness of breath, palpitations, and anxiety as well as characteristic EKG findings and elevation of serum markers including creatine kinase-MB fraction and troponin. [from HPO]

Aspirin resistance

Aspirin (acetylsalicylic acid) is a classic nonsteroidal antiinflammatory agent that irreversibly inhibits type I cyclooxygenase (PTGS1, or COX1; 176805) in platelets, resulting in decreased production of thromboxane A2 (TXA2) and inhibition of platelet aggregation. Because of this feature, it is used therapeutically to prevent cardiothrombotic events. Individuals show a variable response to the drug, referred to as aspirin ineffectiveness or resistance, in which not all individuals or populations appear to receive the full prophylactic or therapeutic benefits (summary by Zhou et al., 2011). Halushka and Halushka (2002) discussed a possible basis for resistance to the cardioprotective effect of aspirin. [from OMIM]
