Chest pain due to coronary ischemia commonly radiates to the arm or neck. [7] Certain individuals such as women, diabetics, and the elderly may present with more varied symptoms. [8] If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack. [9]
Over 90% of healthy men have at least 1 mm (0.1 mV) of ST segment elevation in at least one precordial lead. [7] The clinician must therefore be well versed in recognizing the so-called ECG mimics of acute myocardial infarction, which include left ventricular hypertrophy , left bundle branch block , paced rhythm , early repolarization ...
Women more often present without chest pain and instead have neck pain, arm pain or feel tired. [11] Among those over 75 years old, about 5% have had an MI with little or no history of symptoms.

Consequentially, many will undergo some form of pain treatment and adjust to their new lives as best they can. [medical citation needed] Pain associated with Dejerine–Roussy syndrome is sometimes coupled with anosognosia or somatoparaphrenia which causes a patient having undergone a right-parietal, or right-sided stroke to deny any paralysis ...
