Filter by:To assess the effect of non-surgical reperfusion on infarct size in patients with acute myocardial infarction.
To assess the benefits of a new method of cardiopulmonary resuscitation, SC-V CPR (simultaneous compression and ventilation CPR) in terms of short and long-term survival and lessened cerebral dysfunction.
To test the feasibility and the efficacy of nutritional interventions in the primary prevention of hypertension in individuals predisposed to the development of hypertension; specifically, to test the hypothesis that reduction of weight and/or decreased sodium intake in obese individuals, or decreased sodium intake with or without increased potassium intake (in men and women, regardless of weight) would prevent the elevation of blood pressure and the incidence of hypertension.
To assess the effect on cardiovascular mortality of alternate-day consumption of 325 milligrams of aspirin and, secondarily, the effect on cancer incidence of alternate-day consumption of 50 milligrams of beta-carotene.
The SHEP Pilot Study had six objectives, each designed to develop and test critical components of a full scale trial directed at the health consequences of treating isolated systolic hypertension (ISH) in the elderly. l. To estimate and compare the yield of participants for randomization into a clinical trial from various community groups using various recruitment techniques. 2. To estimate compliance with the visit schedule and to the prescribed double-blind regimens. 3. To estimate and compare the effectiveness of specified antihypertensive medications in reducing the blood pressure. 4. To estimate and compare the unwanted effects of specified antihypertensive medication in an elderly population. 5. To evaluate the feasibility and effectiveness of periodic behavioral assessment in this population. 6. To develop and test methods of ascertaining stroke and other disease endpoints.
To determine whether blood pressure could be controlled by nutritional-hygienic, non-pharmacologic means in hypertensives treated with drugs in the Hypertension Detection and Follow-up Trial (HDFP).
The primary objective of this multicenter cooperative clinical trial was to determine if dietary modification would enable drug controlled hypertensive patients to remain at 'goal blood pressures' after antihypertensive medication was withdrawn. The proposal made use of the HDFP hypertensive population who had five years of treatment for their hypertension. Additionally, the group of investigators proposed to determine if dietary treatment would permit patients not previously adequately controlled under the HDFP program to achieve normalization of blood pressure with a combination of dietary modification and drug treatment. The study also proposed to search for predictors (i.e., levels of hormonal agents such as plasma renin activity) of responsiveness to dietary manipulation among the hypertensive population as well as to identify psychological attributes that might be of importance in managing these patients.
To determine the effectiveness of the platelet inhibitor drugs dipyridamole and aspirin in reducing the angiographic progression of coronary artery disease over a five-year period and to test the predictive value of the platelet survival half-life in identifying patients with more rapid progression of coronary disease and development of its complications.
To determine whether improved nutrition to correct overweight and high sodium intake, and regular frequent moderate rhythmic exercise to improve cardio-pulmonary fitness and to slow heart rate could lower blood pressure and prevent development of hypertension in hypertension-prone individuals.
To evaluate the effects (up to one year of age) of indomethacin on the clinical course of patent ductus arteriosus (PDA) in premature infants (24 hours old or less) and to assess the relative merits of indomethacin and surgery in infants with persistent respiratory distress who were not treated early with indomethacin. Two concurrent trials were performed.
