A Myocardial infarction is also known as what?
heart attack
Title: Myocardial infarction
Passage: Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.  The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw.  Often it is in the center or left side of the chest and lasts for more than a few minutes.  The discomfort may occasionally feel like heartburn.  Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired.  About 30% of people have atypical symptoms.  Women more often have atypical symptoms than men.  Among those over 75 years old, about 5% have had an MI with little or no history of symptoms.  An MI may cause heart failure, an irregular heartbeat, cardiogenic shock, or cardiac arrest.
Title: Death by natural causes
Passage: A death by natural causes, as recorded by coroners and on death certificates and associated documents, is one that is primarily attributed to an illness or an internal malfunction of the body not directly influenced by external forces.  Contrary to the statement before, everything is natural at some point.  For example, a person dying from complications from influenza (an infection) or a heart attack (an internal body malfunction) or sudden heart failure would be listed as having died from natural causes.  Health departments discourage listing old age as the cause of death because doing so does not benefit public health or medical research.  Old age is not a scientifically recognized cause of death; there is always a more direct cause, although it may be unknown in certain cases and could be one of a number of aging-associated diseases.
Title: Strain rate imaging
Passage: Strain rate Imaging is a method in Echocardiography (Medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle).  The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac muscle.  If there is myocardial Ischemia, or there has been an Myocardial infarction, in part of the heart muscle, this part is weakened and shows reduced and altered Systolic function.  Also in regional asynchrony, as in Bundle branch block, there is regional heterogeneity of systolic function.  By strain rate imaging, the simultaneous function of different regions can be displayed and measured.  The method was first based on colour Tissue Doppler.  by using the longitudinal myocardial Velocity gradient, already in use transmurally.  Later, the regional deformation has also been available by Speckle tracking echocardiography, both methods having some, but different methodological weaknesses.  Both methods, however, will acquire the same data (measurements may differ somewhat, however, being method dependent), and also can be displayed by the same type of display.
