Higher circulating levels of docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) appear to be protective against incident atherothrombotic and cardioembolic strokes, respectively, according to a recent study.

The prevalence of resistant hypertension may be lower than expected, particularly once pseudo-resistant hypertension due to treatment nonadherence is taken into account, according to a presentation at the recent APCH 2017.

Psychosocial stress tied to daily myocardial infarction rates

08 Oct 2017

Periods of presumed psychosocial stress are correlated with daily fluctuations in myocardial infarction rates, a new study from Sweden has found.

The study included 156,690 myocardial infraction events (mean age of patients 71.8±12.4 years; 63.7 percent male) grouped according to specific time period and days. Holidays (n=9,835), turns of the month (n=41,246) and Mondays (n=25,338) were all presumed to increase stress; while summers (n=11,935) and weekends (n=40,225), decrease stress.

After adjusting for the whole population, daily myocardial infarction rates were found to be significantly higher during holidays (incidence rate ratio [IRR], 1.07; 95 percent CI, 1.04 to 1.09; p<0.001) and Mondays (IRR, 1.11; 1.09 to 1.13; p<0.001) and significantly lower during summer (IRR, 0.92; 0.90 to 0.94; p<0.001) and weekends (IRR, 0.88; 0.87 to 0.89; p<0.001).

Contrary to what was hypothesized, turns of the month (IRR, 1.01; 1.00 to 1.02; p=0.891) did not correlate significantly with higher daily myocardial infarction rates. Additionally, daily temperatures showed a significant negative association with myocardial infarction rates (IRR per 10oC increase, 0.98; 0.97 to 0.99; p<0.001).

Subgroup analyses also showed that the increase in adjusted daily myocardial infarction rates was higher in males (IRR, 1.14; 1.12 to 1.16; p<0.001) than in females (IRR, 1.06; 1.04 to 1.09; p<0.001), and in working adults (IRR, 1.20; 1.16 to 1.24; p<0.001) than in pensioners (IRR, 1.08; 1.07 to 1.11; p<0.001).

In contrast, the effect of holidays on myocardial infraction rates was significant in pensioners (IRR, 1.09; 1.07 to 1.12; p<0.001) but not in working adults (IRR, 0.99; 0.93 to 1.04; p=0.599).
