Document Summary
Key concepts chronic disease non communicable diseases not passed from person to person long duration progressive. 4 main types of non-communicable diseases: cvd, cancers, chronic respiratory diseases, diabetes. R to exercise after bed rest and after training inactivity (bed rest) decreased o2 uptake and exercise tolerance exercise training restored/ improve o2 uptake (vo2) Peripheral vasculature vascular disease structure of artery/ vein. Elastic lamina (extracellular matrix) pattern of blood flow. Lv heart failure: backs up, accumulation of fluid in lungs = pulmonary edema. Hf-with reduced ejection fraction = systolic dysfunction. decreased contractility fluid retention = edv = esv. Edv = partial improvement in sv lower sv = frank-starling mechanism not working. Edv suppose to esv enlarged ventricles thinner and weaker walls. Hf-with preserved ejection fraction = diastolic dysfunction decreased compliance = more stiff (trouble v ventricular filling) due to frank-starling: edv = sv most common cause: hypertension thick walls.
