TL;DR: Male sex, less education, physical inactivity, cigarette smoking, overweight, diabetes, hypertension, valvular heart disease, and coronary heart disease are all independent risk factors for CHF.
Abstract: Background: The incidence of congestive heart failure (CHF) has been increasing steadily in the United States during the past 2 decades. We studied risk factors for CHF and their corresponding attributable risk in the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. Participants and Methods: A total of 13643 men and women without a history of CHF at baseline examination were included in this prospective cohort study. Risk factors were measured using standard methods between 1971 and 1975. Incidence of CHF was assessed using medical records and death certificates obtained between 1982 and 1984 and in 1986, 1987, and 1992. Results: During average follow-up of 19 years, 1382 CHF cases were documented. Incidence of CHF was positively and significantly associated with male sex (relative risk [RR], 1.24; 95% confidence interval [CI], 1.10-1.39; P,.001; population attributable risk [PAR], 8.9%), less than a high school education (RR, 1.22; 95% CI, 1.04-1.42; P=.01; PAR, 8.9%), low physical activity (RR, 1.23; 95% CI, 1.09-1.38; P,.001; PAR, 9.2%), cigarette smoking (RR, 1.59; 95% CI, 1.39-1.83; P,.001; PAR, 17.1%), overweight (RR, 1.30; 95% CI, 1.12-1.52; P=.001; PAR, 8.0%), hypertension (RR, 1.40; 95% CI, 1.241.59; P,.001; PAR, 10.1%), diabetes (RR, 1.85; 95% CI, 1.51-2.28; P,.001; PAR, 3.1%), valvular heart disease (RR, 1.46; 95% CI, 1.17-1.82; P=.001; PAR, 2.2%), and coronary heart disease (RR, 8.11; 95% CI, 6.95-9.46; P,.001; PAR, 61.6%). Conclusions: Male sex, less education, physical inactivity, cigarette smoking, overweight, diabetes, hypertension, valvular heart disease, and coronary heart disease are all independent risk factors for CHF. More than 60% of the CHF that occurs in the US general population might be attributable to coronary heart disease. Arch Intern Med. 2001;161:996-1002

TL;DR: It is indicated that high sodium intake is strongly and independently associated with an increased risk of cardiovascular disease and all-cause mortality in overweight persons and dietary sodium intake was not significantly associated with cardiovascular disease risk in nonoverweight persons.
Abstract: ContextDietary sodium is positively associated with blood pressure, and ecological and animal studies both have suggested that high dietary sodium intake increases stroke mortality.ObjectiveTo examine the risk of cardiovascular disease associated with dietary sodium intake in overweight and nonoverweight persons.DesignProspective cohort study.SettingThe first National Health and Nutrition Examination Survey Epidemiologic Follow-up Study, conducted in 1982-1984, 1986, 1987, and 1992.ParticipantsOf those aged 25 to 74 years when the survey was conducted in 1971-1975 (14,407 participants), a total of 2688 overweight and 6797 nonoverweight persons were included in the analysis.Main Outcome MeasuresDietary sodium and energy intake were estimated at baseline using a single 24-hour dietary recall method. Incidence and mortality data for cardiovascular disease were obtained from medical records and death certificates.ResultsFor overweight and nonoverweight persons, over an average of 19 years of follow-up, the total number of documented cases were as follows: 680 stroke events (210 fatal), 1727 coronary heart disease events (614 fatal), 895 cardiovascular disease deaths, and 2486 deaths from all causes. Among overweight persons with an average energy intake of 7452 kJ, a 100 mmol higher sodium intake was associated with a 32% increase (relative risk [RR], 1.32; 95% confidence interval [CI], 1.07-1.64; P = .01) in stroke incidence, 89% increase (RR, 1.89; 95% CI, 1.31-2.74; P<.001) in stroke mortality, 44% increase (RR, 1.44; 95% CI, 1.14-1.81; P = .002) in coronary heart disease mortality, 61% increase (RR, 1.61; 95% CI, 1.32-1.96; P<.001) in cardiovascular disease mortality, and 39% increase (RR, 1.39; 95% CI, 1.23-1.58; P<.001) in mortality from all causes. Dietary sodium intake was not significantly associated with cardiovascular disease risk in nonoverweight persons.ConclusionsOur analysis indicates that high sodium intake is strongly and independently associated with an increased risk of cardiovascular disease and all-cause mortality in overweight persons.

TL;DR: Folic acid supplementation has not been shown to reduce risk of cardiovascular diseases or all-cause mortality among participants with prior history of vascular disease and several ongoing trials with large sample sizes might provide a definitive answer.
Abstract: ContextEpidemiologic studies have suggested that folate intake decreases risk of cardiovascular diseases. However, the results of randomized controlled trials on dietary supplementation with folic acid to date have been inconsistent.ObjectiveTo evaluate the effects of folic acid supplementation on risk of cardiovascular diseases and all-cause mortality in randomized controlled trials among persons with preexisting cardiovascular or renal disease.Data SourcesStudies were retrieved by searching MEDLINE (January 1966-July 2006) using the Medical Subject Headings cardiovascular disease, coronary disease, coronary thrombosis, myocardial ischemia, coronary stenosis, coronary restenosis, cerebrovascular accident, randomized controlled trial, clinical trials, homofolic acid, and folic acid, and the text words folic acid and folate. Bibliographies of all retrieved articles were also searched, and experts in the field were contacted.Study SelectionFrom 165 relevant retrieved reports, 12 randomized controlled trials compared folic acid supplementation with either placebo or usual care for a minimum duration of 6 months and with clinical cardiovascular disease events reported as an end point.Data ExtractionData on study design, characteristics of participants, changes in homocysteine levels, and cardiovascular disease outcomes were independently abstracted by 2 investigators using a standardized protocol.Data SynthesisStudies including data from 16 958 participants with preexisting vascular disease were analyzed using a random-effects model. The overall relative risks (95% confidence intervals) of outcomes for patients treated with folic acid supplementation compared with controls were 0.95 (0.88-1.03) for cardiovascular diseases, 1.04 (0.92-1.17) for coronary heart disease, 0.86 (0.71-1.04) for stroke, and 0.96 (0.88-1.04) for all-cause mortality. The relative risk was consistent among participants with preexisting cardiovascular or renal disease.ConclusionsFolic acid supplementation has not been shown to reduce risk of cardiovascular diseases or all-cause mortality among participants with prior history of vascular disease. Several ongoing trials with large sample sizes might provide a definitive answer to this important clinical and public health question.

TL;DR: In those older than age 50, systolic blood pressure of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP, and hypertension will be controlled only if patients are motivated to stay on their treatment plan.
Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.
