Cardiovascular death 1.5X more likely if less than 20 ng of Vitamin D – 22nd meta-analysis Nov 2019
Cardiovascular deaths 12 percent less likely if have 10 ng more vitamin D – meta-analysis March 2017
perhaps need 10 ng more vitamin D for every 10 degrees further from equator

Heart Attacks also vary with Season
BACKGROUND:
We investigated whether the incidence of death following myocardial infarction (MI) varied by season and latitude in the Swedish population.METHODS:
We studied deaths following MI from January 1987 to December 2009, using the Swedish National Cause of Death Register. County of residence was used to determine latitude and population density. An extension of Poisson regression was used to study the relationship between risk of death following MI with age, latitude, time (from 1987), population density and calendar days.RESULTS:
Over the study period, there was a secular decrease in the incidence of MI-related death.
In men, MI-related death incidence increased by 1.3% [95% confidence interval (CI) = 1.1-1.5] per degree of latitude (northwards).
In women, MI-related death incidence increased by 0.6% (95% CI = 0.4-0.9) per degree of latitude.There was seasonal variation in the risk of MI-related death with peak values in the late winter and a nadir in the summer months in both the north and the south of Sweden. Findings were similar with incident MI as the outcome.
CONCLUSIONS:
The incidence of MI-related death varied markedly by season and latitude in Sweden, with summer months and more southerly latitude associated with lower rates than winter months and more northerly latitude.Heart Attacks in men 13 percent more likely if 10 degrees further North (Sweden) – Nov 2019(Cached) Printer Friendly Follow this page for updates4740 visitors, last modified 28 Nov, 2019, This page is in the following categories (# of items in each category)Attached files
