The heart in relation to dentistry is the topic of this chapter. Heart physiology is described with respect to the cardiac cycle, control of contraction, ECG, and arrhythmias. Control of the cardiovascular system is next considered and the clinical application of this in fainting, shock, and blood loss. Atherosclerosis, angina, and myocardial infarction are described. This leads to a discussion of heart failure and drugs commonly used in cardiovascular disease. Infective endocarditis and rheumatic fever are discussed and the associations between oral bacteria and cardiovascular disease. The concluding section deals with stroke (cerebrovascular accident or CVA), transient ischaemic attacks (TIA) and vascular dementia.
