“…On rather cool days, atrial fibrillation occurs more frequently than on warmer days. 8,14,15 In our analysis, the occurrence of ALI did not increase on days with an outside temperature below 10 C. Therefore, the hypothesis that the incidence of ALI might be dependent on the outside temperature or the hematocrit level was not confirmed.…”

“…6 Such arrhythmias are known to occur more likely with lower environmental temperatures. 7 It has been published that the incidence of paroxysmal atrial fibrillation may be influenced by meteorological conditions 8 and shows seasonal variation with a maximum peak in fall and minimal incidence in summer. 9 It has also been shown that an increased hematocrit level is associated with PAD independent of cardiovascular risk factors, and that high plasma viscosity contributes to femoropopliteal restenosis.…”

Differences in Cardiovascular Risk Factors Between Patients With Acute Limb Ischemia and Intermittent Claudication

et al. 2013

In this retrospective study, cardiovascular risk factors of patients with acute limb ischemia (ALI) were compared with those of intermittent claudication (IC). Furthermore, the association of ALI with environmental temperature and/or hematocrit level was tested. A total of 436 patients treated for ALI and 832 patients with IC were included in the analysis. Diabetes (P = .0001), smoking (P < .0001), and hypertension (P < .0001) were significantly less prevalent in the patients with ALI. Patients with IC had a higher rate of coronary artery disease (P = .003), and patients with ALI had a higher rate of cerebrovascular disease (P < .0001). There was no association between the outside temperature or hematocrit level and the occurrence of ALI. The hypothesis of seasonal incidence of ALI could not be confirmed, and there was no association of ALI with the hematocrit level.

“…[145] Studies performed in Japan showed maximum AF incidence in autumn, with a significant reduction in summer. [146] Similarly, six studies on the seasonality of AF, In Israel,[147] Finland[148] Poland,[149150] Scotland,[151] and Australia[152] found the peak of incidence during winter months. In contrast, the peaks for AF hospitalizations in Canada were found predominantly in spring and the troughs in summer.…”

This paper review seasonal patterns across twelve cardiovascular diseases: Deep venous thrombosis, pulmonary embolism, aortic dissection and rupture, stroke, intracerebral hemorrhage, hypertension, heart failure, angina pectoris, myocardial infarction, sudden cardiac death, venricular arrythmia and atrial fibrillation, and discuss a possible cause of the occurrence of these diseases. There is a clear seasonal trend of cardiovascular diseases, with the highest incidence occurring during the colder winter months, which have been described in many countries. This phenomenon likely contributes to the numbers of deaths occurring in winter. The implications of this finding are important for testing the relative importance of the proposed mechanisms. Understanding the influence of season and other factors is essential when seeking to implement effective public health measures.

“…[12,25,26] Shoben et al [14] illustrated a sinusoidal pattern for mean monthly 25[OH]D concentration, with low levels throughout winter corresponding to the seasonal increase in AF incidence, suggesting that vitamin D levels may be responsible. As such, the seasonal variation in vitamin D levels due to changes in ultraviolet exposure must be taken in to account when designing and interpreting studies investigating vitamin D and AF.…”
