This is my version of how to take a decent cardiovascular history and cover all the relevant points! I have included things like drugs that you should automatically realise are to do with the cardiovascular system but this may not be useful for higher year students as I am just a first year! Hope this helps at least someone!

Following the implantation of the blastocyst into the endometrium of uterus, the embryo begins another important embryological process called gastrulation. Gastrulation is the formation of the three distinct germ layers - the ectoderm, the mesoderm and the endoderm. The ectoderm is the outermost layer of the developing embryo and it consists of cells that eventually give rise to the integumentary system (the outer skin, nails and hair) as well as the nervous system (central and peripheral system). The mesoderm is the middle layer of the developing embryo and it consists of cells that eventually give rise to the musculoskeletal system (bone, cartilage, skeletal muscle, cardiac muscle, smooth muscle), cardiovascular system (the heart and blood vessels), excretory system (kidneys) and reproductive system (gonads). The endoderm is the innermost layer of the developing embryo and it gives rise to the epithelial layer of the digestive tract, lungs, pancreas, bladder, liver as well as the thyroid gland, parathyroid gland and thymus.

Atherosclerosis is the condition in which an artery wall thickens as the result of a build-up of fatty materials such as cholesterol.It most commonly becomes seriously symptomatic when interfering with the coronary circulation supplying the heart or cerebral circulation supplying the brain, and is considered the most important underlying cause of strokes, heart attacks, and most cardiovascular diseases, in general. A stent is a man-made 'tube' inserted into a natural passage/conduit in the body to prevent, or counteract, a disease-induced, localized flow constriction. Stents are used to counter narrowing of arteries due to plaque deposition and hardening.
