Lack of superiority of the vectorcardiogram over the electrocardiogram in detecting inferior wall myocardial infarction regardless of time since infarction.

Using more recent VCG and ECG criteria, the relative accuracy of these two tests in detecting inferior wall MI over time was evaluated in 38 of 236 patients undergoing elective left ventriculographic and coronary angiographic studies who had clinical plus angiographic evidence of inferior wall myocardial infarction. The overall sensitivity and specificity of the ECG criteria of the New York Heart Association and Warner did not differ from that of the VCG criteria of Starr and Takatsu. There was a trend toward decreased sensitivity in both VCG criteria and the ECG criterion of Warner in detecting inferior wall myocardial infarction greater than or equal to 18 months, although the difference did not reach statistical significance. Changing the age of infarction to greater than or equal to 3, greater than or equal to 6, greater than or equal to 12, or greater than or equal to 24 months did not yield a different result. It is concluded that VCG is not superior to ECG in the diagnosis of inferior wall MI regardless of time since occurrence of infarction.

Prevention of some complications of essential hypertension.

The major reason for treating hypertension is to avoid complications of the disease as it affects "target organs." Treatment of the blood pressure is not the only way to avoid these complications, but it is part of the total practice of preventive medicine. Hypertension lasts for several decades in most patients, and there is time to destroy the patient through target organ effects or to save the patient through treatment. Diabetes, atherosclerosis, and other illnesses and operations pose special hazards to the patient with hypertension. Patients take many other drugs as well, and some of them react adversely with antihypertension medicines. Complications from blood pressure drugs involve nearly every organ system, more than most physicians can remember. These may be dose-related and can often be avoided by using smaller doses of more than one drug. Certain problems occur so frequently that they should be learned well. The physician should bear in mind that whatever develops may be due to the antihypertensive therapy. On the whole, however, medications for treatment of hypertension are remarkably safe and free from side effects.

Helping the hypertensive patient to help himself.

The control of blood pressure in patients with hypertension is an important challenge in everyday medical practice. It can do much to reduce complications, but too often we fall short of our therapeutic goals. Much more can be done to help our patients help themselves if physicians, along with their paramedical staffs and their patients, make the effort. The results are gratifying in terms of motivation and successful long-term control of the blood pressure and the risks associated with hypertension. This paper outlines objectives and practical approaches to patient education and self-care of this common medical problem.
