Myocardial infarction (MI) refers to tissue death (infarction) of the heart muscle (myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [ 22 ]
Death is defined as the cessation of all vital functions of the body including the heartbeat, brain activity (including the brain stem), and breathing. Description. Death comes in many forms, whether it be expected after a diagnosis of terminal illness or an unexpected accident or medical condition. Terminal illness.

This is another way of saying an abnormal heart rhythm. This is usually due to faulty conduction of electricity through the heart. There are many different types of arrhythmia which can be managed differently, including medication, a pacemaker or an ICD (an internal defibrillator). See also “heart block”. 1. Learn about treatments for abnormal hear...
This is a common abnormal heart rhythm that happens when electrical impulses fire off from different places in the atria (the top chambers of the heart) in a disorganised way. This causes the atria to twitch, and results in an irregular heartbeat or pulse. Atrial fibrillation is a major cause of stroke. 1. Find out what it's like living with atrial...
This occurs suddenly and without warning. The most common cause of a cardiac arrest is a heart attack, but there are other causes. In cardiac arrest there is an electrical malfunction in the heart, resulting in an irregular heartbeat that disrupts the effective pumping action of the heart. As a result, the heart cannot pump blood to the brain and o...
This means a stroke. A stroke can occur in two forms. There can be a blockage of the blood vessels supplying the brain, and this starves the brain of blood and oxygen causing its death. This is known as an ischaemic stroke. This kind of stroke is usually caused by atherosclerosis, the same process that leads to coronary heart disease, including hea...
This is the pressure of blood flow in the arteries as the heart relaxes and prepares for the next contraction (heart beat). It is measured in millimetres of mercury (mmHg). 1. Find out why you should know your blood pressure.
A heart block is an abnormal heart rhythm (arrhythmia) that happens when the electrical impulses that tell your heart when to beat are delayed or blocked as they travel through your heart. Some heart blocks will not cause any symptoms, but others are more serious and may need treatment such as a pacemaker.
Heart failureis a condition whereby the heart muscle is unable to pump blood around the heart effectively. This usually occurs because the heart muscle has become stiffened or weak. It is a long-term condition which worsens over time and requires medical management. Symptoms include shortness of breath, leg swelling and lethargy. Symptoms can devel...
Hypertension means high blood pressure. This is clinically defined as blood pressure consistently above 140/90 mmHg. The two numbers in a blood pressure reading refer to the systolic and diastolicblood pressure respectively. 1. Get our 6 top tips for reducing your blood pressure.
Ischaemic cardiomyopathy (IC) is a condition when your heart muscle is weakened as a result of a heart attack or coronary artery disease. This can result in heart muscle damage, which leads to heart failure. The word “ischaemic” means there is a problem with blood supply to a particular part of the body, while “cardiomyopathy” is a general term for...
This refers to the disease process,atherosclerosis, which causes narrowing of the blood vessels supplying the heart muscle. This results in impaired blood flow to the heart muscle causing symptoms including chest pain (angina) and shortness of breath. This disease process can ultimately result in a heart attack. 1. Watch our animation to learn all ...
Death is a process involving cessation of physiological functions, and the determination of death is the final event in that process. For most people, death takes occurs with the confirmation of irreversible cessation of cardiorespiratory function.
Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and/or diaphoresis. Diagnosis is by electrocardiography (ECG) and the presence or absence of biomarkers.
myocardial infarction (MI) death of the cells of an area of the heart muscle as a result of oxygen deprivation, which in turn is caused by obstruction of the blood supply; commonly referred to as a “heart attack.”
Apr 8, 2024 · Patients with an adjudicated diagnosis of type 1 MI without a clinical diagnosis were more likely to be women (eg, 336 women [49%] vs 909 women [36%] in Scotland; P < .001) and older (mean [SD] age, 71 [14] v 67 [14] years in Scotland, P < .001) and, when adjusting for competing risk from noncardiovascular death, were at similar or increased risk of subsequent MI or cardiovascular death ...
