Myocardial infarction causes pain which is similar 10 angina in site, radiation and character but differs in that it is not necessarily precipitated by exertion, persists at rest and is usually much more severe (Table 3.9). Autonomic symptoms such as sweating, nausea and vomiting may be associated with myocardial infarction. Patients may also be breathless, reslless and distressed and may experience a sensation of impending death, angor amini. Conversely, painless myocardial infarction is not uncommon particularly in elderly patients and those with diabetes. Such patients may present with complications such as cardiac failure or an arrhythmia.
