Topical over the counter antibiotics should be applied as soon as possible after injury (after the injury has been cleansed and dried, of course). A gauze dressing is ideal, as it lets the wound breathe but keeps out infection-causing dirt.
Coronary heart disease - Causes. Coronary heart disease (CHD) is usually caused by a build-up of fatty deposits (atheroma) on the walls of the arteries around the heart (coronary arteries). The build-up of atheroma makes the arteries narrower, restricting the flow of blood to the heart muscle. This process is called atherosclerosis.
Coronary heart disease is caused by any problem with the coronary arteries that keeps the heart from getting enough oxygen- and nutrient-rich blood. The most common cause by far is atherosclerosis. Lack of sufficient blood is called ischemia, so coronary heart disease is sometimes called ischemic heart disease.
