“…Daily counts of death due to MI were associated with snowfalls in Pennsylvania, Rhode Island and Minneapolis-St. Paul, all located in the northern regions of the United States. 9,16 A correlation between snowfall and incidence of MI was also reported in Switzerland, 15 which has a climate somewhat comparable to Quebec's. In contrast, the frequency of hospital admission due to MI was not associated with snowfall in a Swedish sample of 382 patients.…”

“…[12][13][14] Snowfall is flagged as a possible MI risk factor in northern countries, 9,10,15,16 but evidence based on aggregate patient data is conflicting. 9,10,12,[15][16][17][18][19][20] Because the analysis of aggregate data can result in a loss of statistical power 21 and carries a risk of ecologic bias, 22 conclusive evidence of an association between snowfall and MI has yet to be established. Extreme weather patterns, including blizzards, are predicted to increase with climate change; 23 thus, an increased risk of MI in connection with snowfall has clear public health implications.…”

BACKGROUND: Although aggregate data suggest a link between snowfall and myocardial infarction (MI), individual risk has yet to be assessed. We evaluated the association between quantity and duration of snowfall and the risk of MI using nonaggregated administrative health data. METHODS:We used a case-crossover study design to investigate the association between snowfall and hospital admission or death due to MI in the province of Quebec, Canada, between November and April during 1981-2014. The main exposure measures were quantity (in centimetres) and duration (in hours) of snowfall by calendar day. We computed odds ratios (ORs) and 95% confidence intervals (CIs) for the association between daily snowfall and MI, adjusted for minimum daily temperatures. RESULTS:In all, 128 073 individual hospital admissions and 68 155 deaths due to MI were included in the analyses. The likelihood of MI was increased the day after a snowfall among men but not among women. Compared with 0 cm, 20 cm of snowfall was associated with an OR of 1.16 for hospital admission (95% CI 1.11-1.21) and 1.34 for death (95% CI 1.26-1.42) due to MI the following day among men. Corresponding ORs among women were 1.01 (95% CI 0.95-1.07) and 1.04 (95% CI 0.96-1.13). Similar but smaller associations were observed for snowfall duration (0 h v. 24 h) and MI. INTERPRETATION:Both the quantity and duration of snowfall were associated with subsequent risk of hospital admission or death due to MI, driven primarily by an effect in men. These data have implications for public health initiatives in regions with snowstorms.

“…However, in addition to the fact that temperature has a major role in the AMI incidence, our results have also showed that lower air pressure (< 1009 hPa) adjusted for the temperature and relative humidity are good predictors of the lower AMI incidence among the examined population (the adults and the elderly). Yet, according to the available literature [22,23], consequences of air pressure on the AMI have not been studied very often on a daily level. One of the studies that examined daily effects of air pressure on the AMI events has reported that a higher occurrence of the AMI is related to atmospheric pressure below 1000 hPa [24].…”

Background: The aim of this study has been to examine the association between climate conditions (CC) and hospital admissions for the subcategories of cardiovascular diseases (CVD), according to patients' age. Material and Methods: From January 2010 through December 2011, the daily number of hospital admissions for angina pectoris (AP), essential hypertension (EH), acute myocardial infarction (AMI) and ischemic heart diseases (IHD) for adults (19-64 years old) and the elderly (≥ 65 years old), as well as for the CC (N = 728 days) was collected for multivariate Poisson regression analysis, confounding with season and weekends. The results were expressed by using the relative risk with the corresponding 95% confidence interval. Results: The risk for the AMI among the adults and the elderly is significantly higher for 41.8% and 38.9%, respectively on the days with lower ambient temperature and lesser for 32.7% and 29.8%, respectively on the days with lower air pressure values. The risk for the IHD among the elderly is significantly higher on the days with lower ambient temperature and lower relative humidity for 50.6% and 37.4%, respectively. Conclusions: Our findings explain how the CC and subcategories of CVD are associated, which could be used for adequate public awareness of the risk for hospitalization due to climate conditions.

“…14 Other climatic variables such as precipitation, humidity, wind speed, and weather fronts have not shown consistent or convincing associations with the incidence of AMI. 15,16 Weather and climate in Halifax is heavily influenced by Nova Scotia's location on the Atlantic Coast and is quite different from central and western Canada. e strong maritime influence prevents wide temperature fluctuations (usual range from -15 to +25 C), and causes abundant precipitation year round in the form of snow, rain, fog and ice mixes.…”
