In minorities, as in the general population, hypertension is taken seriously because it is a risk factor for cardiovascular disease. Until recently, our understanding of the role that hypertension plays in the heart disease seen in minorities has been limited by a paucity of prospective data regarding the prevalence, natural history, and pathophysiology of the disease process in minority populations. In the last few years large-scale epidemiologic studies and well-controlled clinical studies alike have confirmed usually high rates of hypertension-related morbidity and mortality in minorities, particularly blacks and Hispanics. ⋯ Inner-city patients are, increasingly, black and Hispanic patients, and these patients are more likely to be underinsured or uninsured, to be functionally illiterate in English, to be disinclined to seek health care, and to be less capable of following a prescribed regimen than the populace as a whole. The nature of the therapeutic regimen itself is probably the most important determinant of compliance, and compliance with drug therapy will be improved if the clinic chooses a simplified drug regimen and avoids drugs that produce intolerable side effects. Once-a-day--or, with transdermal clonidine, one-a-week--single-drug therapy may not be possible in all patients, but multiple drug therapy and multiple daily dosing schedules should be avoided wherever possible.

Comparative Study
Improving compliance in an inner-city hypertensive patient population.
Because hypertension is a "silent" disease process, compliance with therapy is always a problem. In the inner city, where socioeconomic factors such as poverty, illiteracy, and substance abuse raise additional barriers to effective health care, poor compliance with antihypertensive regimens can reach epidemic proportions--as it did in our clinic in the early 1970s. After identifying the major causes of poor compliance in our patients, we instituted measures that led directly to greatly improved compliance and control, among them the expansion of clinic hours, the expediting of laboratory services, and the training of nurse-therapists to assume many of the responsibilities of running the clinic. ⋯ To test this hypothesis, we enrolled 20 patients, all of them blacks, in a pilot study of this unique delivery system. Blood pressure was adequately controlled in all 18 patients who completed the study, and patients were uniformly enthusiastic about this alternative to daily dosing. As a result, compliance with this mode of therapy was excellent.

Multicenter Study Clinical Trial
Cerebrovascular accident complicating acute myocardial infarction: incidence, clinical significance and short- and long-term mortality rates. The SPRINT Study Group.
The purpose of this study was to report the incidence, the antecedents, and the clinical significance of clinically recognized cerebrovascular accidents or transient ischemic attacks (CVA-TIA) complicating acute myocardial infarction. ⋯ In this large cohort of consecutive patients with myocardial infarction, CVA-TIA was a relatively infrequent complication of acute myocardial infarction. Factors independently favoring the occurrence of CVA-TIA were old age, previous CVA, and congestive heart failure. CVA-TIA occurring during acute myocardial infarction independently increased the risk of early death threefold as well as the risk of long-term mortality in early-phase survivors. (2.5-fold).

Non-insulin-dependent diabetes mellitus (NIDDM) in black Americans consists of two variants: one with insulin resistance and one with normal insulin sensitivity. This study examined whether cardiovascular disease risk factors are significantly different between the two variants. ⋯ Black patients with the insulin-sensitive variant of NIDDM have a low risk factor profile for cardiovascular disease as compared with those with the insulin-resistant variant, who have a high risk factor profile. A high prevalence of the insulin-sensitive variant of NIDDM in the black population might explain the lower prevalence of angina and myocardial infarction in black patients with NIDDM as compared with white patients with NIDDM.

Assessment of the value of determination of antineutrophil cytoplasmic antibodies (ANCA) and its specificities for classification of patients with biopsy-proven necrotizing arteritis. ⋯ Determination of ANCA and its specificities is a useful adjunct to the classification of patients with biopsy-proven necrotizing arteritis. Within the spectrum of idiopathic vasculitides, 29-kd serine protease antibodies are associated with WG, MPO antibodies are associated with Churg-Strauss syndrome and systemic PAN, and PAN limited to the skin and the musculoskeletal system is not associated with ANCA.
