Reducing the incidence of coronary heart disease

The incidence of coronary heart disease (CHD) has been significantly reduced by the introduction of the National Service Framework in 2000 but has not yet reached set targets. This article analyses the adverse effects of specific CHD risk factors to the cardiovascular system and proposes local and national strategies for further reduction in the incidence, morbidity and mortality of CHD. It provides an example of how nurses can use a health promotion programme to support patients in giving up smoking, a major contributing factor in CHD. The programme uses cognitive behaviour therapy to improve patients' uptake and adherence.

Hypertension - a contemporary approach to nursing care

The incidence of hypertension is increasing as the number of patients with obesity and diabetes mellitus increases. Hypertension results when the peripheral vascular resistance is increased, the blood viscosity is elevated and/or the flow of blood through the main arteries is impeded. Chronic hypertension results in enlarged heart, myocardial damage and lung and renal abnormalities. While some causative factors such as obesity can be controlled, others for example genetics are more difficult to treat because often there is more than one factor involved. This paper explores how essential and secondary factors contribute to the incidence of hypertension and the physiological changes resulting from raised blood pressure. It proposes that although traditional treatment has some success, nurse-led clinics are having better success not only in controlling raised blood pressure but also in reducing cardiac, pulmonary and renal morbidity. It is more cost-effective, staff is more productive and clients are more compliant with treatment.
