Myocardial infarction (MI): It's commonly referred to as an attack, which occurs when blood flow decreases or stops to a neighbourhood of the guts, causing damage to the guts muscle. The foremost common symptom is pain or discomfort which can travel into the shoulder, arm, back, neck or jaw. Often it occurs within the centre or left side of the chest and lasts for quite a couple of minutes. The discomfort may occasionally desire heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a chilly sweat or feeling tired. About 30% of individuals have atypical symptoms. Women more often present without pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause coronary failure, an irregular heartbeat, shock or asystole. This is often the irreversible death i.e, necrosis of cardiac muscle secondary to prolonged lack of oxygen supply (ischemia). Approximately 1.5 million cases of MI occur annually within us.

Most MIs occur thanks to arteria coronaria disease. Risk factors include high vital sign, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet and excessive alcohol intake. the entire blockage of a arteria coronaria caused by a rupture of an atherosclerotic plaque is typically the underlying mechanism of an MI. MIs are less commonly caused by arteria coronaria spasms, which can flow from to cocaine, significant emotional stress commonly referred to as Takotsubo syndrome or broken heart syndrome and extreme cold, among others. Varieties of tests are useful to assist with diagnosis, including electrocardiograms (ECGs), blood tests and coronary angiography. An ECG, which may be a recording of the heart's electrical activity, may confirm an ST elevation MI (STEMI), if ST elevation is present. Commonly used blood tests include troponin and fewer often creatine kinase MB.

Treatment of an MI is time-critical. Aspirin is an appropriate immediate treatment for a suspected MI. Nitro-glycerine or opioids could also be wont to help with chest pain; however, they are doing not improve overall outcomes. Supplemental oxygen is suggested in those with low oxygen levels or shortness of breath. during a STEMI, treatments plan to restore blood flow to the guts and include percutaneous coronary intervention (PCI), where the arteries are pushed open and should be stented, or thrombolysis, where the blockage is removed using medications. People that have a non-ST elevation myocardial infarct (NSTEMI) are often managed with the blood thinner heparin, with the extra use of PCI in those at high risk. In people with blockages of multiple coronary arteries and diabetes, arteria coronaria bypass surgery (CABG) could also be recommended instead of angioplasty.
