We next examined alone the fresh new contacts of potassium and you will magnesium out-of drugs which have chance of stroke
Of the dependence on blood pressure as the a threat grounds to own coronary arrest, i used analyses stratified by the reputation of blood pressure levels in the standard
None usage of potassium medications (RR=0.78; 95% CI, 0.69 to 1.22) neither usage of magnesium tablets (RR=0.85; 95% CI, 0.55 to a single.32) try from the danger of complete otherwise ischemic heart attack when you look at the analyses adjusted to own decades only, however, use of potassium supplements turned firmly inversely associated after variations to own reputation of hypertension (RR=0.55; 95% CI, 0.thirty-five so you’re able to 0.86). History of blood pressure level are an effective independent risk grounds getting stroke (RR=2.8; 95% CI, 2.step one, step 3.7) and was on the usage of potassium pills (46% of the 1248 enhance pages was in fact hypertensives, weighed against 19% away from nonusers). The inverse association between the means to access potassium products and likelihood of heart attack from inside the multivariate analyses try separate out of losing weight intakes out-of diet, and additionally potassium, magnesium, and soluble fiber, and you will are stronger one of people that have reasonable fat loss consumption regarding potassium, magnesium, and you will cereal fiber. The newest RR contrasting the big into bottom quintile of potassium consumption is 0.39 on reasonable tertile away from a nutritional get, such as the 3 diet, 0.57 in-between, and you can 0.86 in the large tertile. To help expand decide to try the fresh theory which use out-of potassium products minimizes the possibility of coronary attack, i opposed males whom stated playing with supplements in 1986 and you may 1988 having boys exactly who never utilized tablets. In 6 remaining many years of go after-up, the latest multivariate RR off complete coronary attack certainly one of enhance users is 0.30 (95% CI, 0.twelve, 0.85; P=0.02); the risk of heart attack was also faster one of men just who advertised having fun with potassium pills just inside 1986 (0.46; 95% CI, 0.twenty two, 0.98; P=0.05) however certainly guys who already been providing drugs inside the 1988 (step 1.07; 95% CI, 0.55, dos.11).
Inverse contacts ranging from nutrient intakes and risk of coronary attack was basically seen simply one of hypertensive guys (Data dos and you may step 3 ). For the analyses simply for boys providing diuretics from the baseline, alone or perhaps in consolidation along with other antihypertensive pills, the latest RR from heart attack to own users away from potassium drugs weighed against nonusers was 0.thirty-six (95% CI, 0.18, 0.72; P=0.004). Both dietary fiber and you will cereal soluble fiber have been notably inversely with the risk away from heart attack one of hypertensive (RRs to possess a great ten-grams rise in intake had been 0.59 and you will 0.33, respectively) yet not one of normotensive (RRs was 0.88 for both) males.
Conversation
Within higher prospective studies, i unearthed that people with diet highest in the potassium, cereal dietary fiber, and you can magnesium got a substantially smaller danger of coronary arrest. These inverse associations had been only partly said by the nondietary risk products however, was solid and you will tall merely certainly men which have detected blood pressure levels. No high connectivity was in fact receive between consumption regarding salt and you can calcium supplements and you will likelihood of coronary attack.
5 21 Into the a ong Japanese men during the Their state, potassium intake try inversely pertaining to danger of fatal thromboembolic heart attack (RR to your finest in place of the base quintile from consumption=0.step 3, P to possess development=0.002) yet not that have risk of nonfatal thromboembolic heart attack (RR=0.87, P to possess trend=0.12). 2 The fresh new weak organization which have nonfatal incidents isn’t contradictory having a safety impact, which may have started diluted of the mistake throughout the single 24-hour remember– established weight-loss review. Inside randomized trials, highest potassium intake has triggered small reduced blood pressure, specifically certainly hypertensive victims. six eight That it impression, but not, are smaller than average is only able to partially explain the good inverse association found in this research. As well, improvement to own baseline hypertension had little impact on the brand new projected RRs linked potassium intake in order to stroke occurrence, and potassium intake was not a critical predictor regarding likelihood of blood circulation pressure in this cohort. 14 Option systems advised include the suppression out-of totally free significant formation, vascular easy muscle growth, and you will arterial thrombosis. 22 not, these types of consequences was produced by fresh expands from inside the solution potassium density when you look at the animals, as well as their advantages to help you humans is unsure. Highest potassium intake can get raise serum levels, particularly when intake was lowest otherwise sodium intake is large, twenty-two and might ergo reduce the threat of hypokalemia certainly one of guys at high risk due to diuretic therapy. Diuretic-triggered hypokalemia could raise the risk of ventricular dysrhythmia. 23 twenty-four Even though no enhanced death away from heart disease and other reasons is actually discover among guys with lower solution potassium in two previous studies, twenty five 26 neither are big enough in order to locate a particular organization ranging from gel potassium and you can chance of coronary arrest.
