#Marijuana Use in Patients With #Cardiovascular Disease: JACC Review Topic of the Week

Marijuana use is increasing as more states are legalizing cannabis for both medicinal and recreational purposes. National survey data estimate that >2 million Americans with established cardiovascular diseases currently use or have used marijuana in its variety of forms, including inhalation and vaping. Cannabinoid receptors are distributed in multiple tissue beds and cells, including platelets, adipose tissue, and myocytes. Observational data suggest associations between marijuana … Continue reading #Marijuana Use in Patients With #Cardiovascular Disease: JACC Review Topic of the Week

High-#protein diets increase #cardiovascular risk by activating macrophage mTOR to suppress mitophagy

High-protein diets are commonly utilized for weight loss, yet they have been reported to raise cardiovascular risk. The mechanisms underlying this risk are unknown. Here, we show that dietary protein drives atherosclerosis and lesion complexity. Protein ingestion acutely elevates amino acid levels in blood and atherosclerotic plaques, stimulating macrophage mammalian target of rapamycin (mTOR) signalling. This is causal in plaque progression, because the effects of … Continue reading High-#protein diets increase #cardiovascular risk by activating macrophage mTOR to suppress mitophagy

Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal

Studies show that a single bout of exercise confers cognitive benefits. However, many individuals use psychoactive substances such as caffeine to enhance cognitive performance.. The objectives of this study were to compare the effects of acute moderate intensity aerobic exercise to caffeine on working memory (WM) and caffeine withdrawal symptoms (CWS). In Phase I, non-caffeine (n = 29) and caffeine consumers (n = 30) completed a WM assessment, followed … Continue reading Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal

Five-Year Outcomes of Transcatheter or Surgical #Aortic-Valve Replacement

..At 5 years, there was no significant difference in the incidence of death from any cause or disabling stroke between the TAVR group and the surgery group (47.9% and 43.4%, respectively; hazard ratio, 1.09; 95% confidence interval [CI], 0.95 to 1.25; P=0.21). Results were similar for the transfemoral-access cohort (44.5% and 42.0%, respectively; hazard ratio, 1.02; 95% CI, 0.87 to 1.20), but the incidence of … Continue reading Five-Year Outcomes of Transcatheter or Surgical #Aortic-Valve Replacement

Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study

..Higher alcohol consumption (β=0.03, p<0.001), lower physical activity (β=0.002,p=001), smoking (β=1.58, p<0.001), men (p<0.001), African-Americans (p<0.001), impaired left ventricular relaxation (e´,β=-0.13, p=0.002), and worse diastolic function (E/e´,β=0.1, p=0.01) were associated with longitudinal increases in resting heart rate. We observed 268 cardiovascular disease and 74 heart failure events over a median of 26 years. In Cox models, baseline and temporal changes in resting heart rate were … Continue reading Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study

Association of Isolated Diastolic #Hypertension as Defined by the 2017 ACC/AHA Blood Pressure Guideline With Incident Cardiovascular Outcomes

..the definition of hypertension was lowered from a blood pressure (BP) of greater than or equal to 140/90 to greater than or equal to 130/80 mm Hg. The new diastolic BP threshold of 80 mm Hg was recommended based on expert opinion and changes the definition of isolated diastolic hypertension (IDH). atherosclerotic cardiovascular disease (ASCVD) ..Compared with normotensive ARIC participants, IDH by the 2017 ACC/AHA … Continue reading Association of Isolated Diastolic #Hypertension as Defined by the 2017 ACC/AHA Blood Pressure Guideline With Incident Cardiovascular Outcomes

Implications of Abnormal Exercise Electrocardiography With Normal Stress Echocardiography

..After excluding submaximal tests and nondiagnostic ECG or stress imaging results, 15 077 patients (mean [SD] age, 52 [13] years; 6228 [41.3%] men) were classified by stress test results Death occurred in 425 patients with −ECG/−Echo (4.8%), 50 patients with +ECG/−Echo (5.9%), and 70 patients with +Echo (11.2%). Myocardial infarction occurred in 195 patients with −ECG/−Echo (2.2%), 31 patients with +ECG/−Echo (3.6%), and 59 patients with … Continue reading Implications of Abnormal Exercise Electrocardiography With Normal Stress Echocardiography

Abdominal #obesity and the risk of recurrent atherosclerotic cardiovascular disease after myocardial #infarction

..Univariate and multivariable-adjusted Cox regression models were used to calculate hazard ratios and 95% confidence intervals in quintiles of waist circumference as well as three categories of body mass index including normal weight, overweight and obesity. Results The majority of patients had abdominal obesity. During a median follow-up time of 3.8 years, 1232 men (7.3%) and 469 women (7.9%) experienced a recurrent atherosclerotic cardiovascular disease … Continue reading Abdominal #obesity and the risk of recurrent atherosclerotic cardiovascular disease after myocardial #infarction

#Walnuts and Vegetable Oils Containing Oleic Acid Differentially Affect the Gut Microbiota and Associations with #Cardiovascular Risk Factors: Follow-up of a Randomized, Controlled, Feeding Trial in Adults at Risk for Cardiovascular Disease

..Forty-two adults at cardiovascular risk were included in a randomized, crossover, controlled-feeding trial that provided a 2-wk standard Western diet (SWD) run-in and three 6-wk isocaloric study diets: a diet containing whole walnuts (WD; 57–99 g/d walnuts; 2.7% ALA), a fatty acid–matched diet devoid of walnuts (walnut fatty acid–matched diet; WFMD; 2.6% ALA), and a diet replacing ALA with oleic acid without walnuts (oleic acid … Continue reading #Walnuts and Vegetable Oils Containing Oleic Acid Differentially Affect the Gut Microbiota and Associations with #Cardiovascular Risk Factors: Follow-up of a Randomized, Controlled, Feeding Trial in Adults at Risk for Cardiovascular Disease

Sex Differences in Blood #Pressure Trajectories Over the Life Course

..Women compared with men exhibited a steeper increase in BP that began as early as in the third decade and continued through the life course (likelihood ratio test χ2 = 531 for systolic BP; χ2 = 123 for diastolic BP; χ2 = 325 for MAP; and χ2 = 572 for PP; P for all <.001). After adjustment for multiple cardiovascular disease risk factors, these between-sex differences in all BP trajectories persisted (likelihood ratio … Continue reading Sex Differences in Blood #Pressure Trajectories Over the Life Course

Associations between Serum Levels of #Cholesterol and #survival to Age 90 in Postmenopausal Women

Although elevated lipid levels predict increased risk of coronary heart disease and death in middle‐aged women and men, evidence is mixed if lipid levels measured in later life predict survival to very old ages.. HDL and LDL levels were not associated with survival to age 90 after adjustment for cardiovascular risk factors.. Similarly, no associations were observed between HDL and LDL levels and survival to … Continue reading Associations between Serum Levels of #Cholesterol and #survival to Age 90 in Postmenopausal Women
