A 60-year-old woman with a history of obesity and DM II has experienced a myocardial infarction (heart attack) that caused permanent damage to the papillary muscle of the left ventricle, resulting in a failure of the mitral valve to close. Her blood pressure is 95 over 55, her breathing rate is about 30 breaths per minute, and her heart rate is 125 per minute. Her breathing is labored and you hear gurgling when you listen through a stethoscope. Her worried son asks you, "What is myocardial infarction, what do her symptoms mean, and what does mitral failure imply?"
