Disorders
Blood pressure
-
-
Hypertension - Sustained elevated arterial pressure of 140/90 mm Hg or higher, heart must work harder; myocardium enlarges, weakens, and becomes flabby
-
Heart
Angina pectoris - Thoracic pain caused by fleeting deficiency in blood delivery to myocardium as a result cells are weakened
-
-
-
-
-
Cardiac Output
Coronary atherosclerosis - clogged arteries caused by fat buildup; impairs oxygen delivery to cardiac cells
Congestive heart failure (CHF) – Progressive condition; CO is so low that blood circulation is inadequate to meet tissue needs
Dilated cardiomyopathy (DCM) - ventricles stretch and become flabby, and myocardium deteriorates
