“…This hypothesis is supported by the circadian pattern in the incidence of SAH, 32 intracerebral hemorrhage, 33 and stroke in general, 34 being highest in the morning when elevations in blood pressure and heart rate occur in parallel with the commencement of activity.…”

Background and Purpose-Unaccustomed strenuous physical exertion can trigger myocardial infarction, but little is known about the mechanisms precipitating subarachnoid hemorrhage (SAH). Methods-We identified all cases of first-ever SAH among the combined populations (2.8 million) of 4 urban centers in Australia and New Zealand. Information on the type, time, and intensity of exposures in the 26 hours before the onset of SAH was ascertained by structured interviews. We used the case-crossover technique to assess the risk of SAH associated with transient exposures of moderate to extreme physical exertion, heavy cigarette smoking, and binge alcohol consumption. Results-We registered 432 first-ever cases of SAH (62% women; mean age, 56.5 years). A definite time of onset of SAH was established for 393 patients (91%), and information on the levels of physical activity in the preceding 26 hours was obtained in 338 (78%). Of these patients, 19% engaged in moderate to extreme exertion (Ն5 metabolic equivalents) in the 2 hours before SAH, which was associated with a tripling in the risk of SAH (odds ratio [OR], 2.7; 95% CI, 1.6 to 4.6). There was no evidence of any association between heavy cigarette smoking or binge drinking and risk of SAH in the subsequent 2 hours (OR, 1.1; 95% CI, 0.4 to 3.7; and OR, 0.41; 95% CI, Ϫϱ to 5.3). Habitual exercise did not appear to alter the risk of SAH associated with moderate to extreme exertion. Conclusions-Moderate to extreme physical exertion tripled the risk of SAH, but there was no association between transient heavy smoking or binge drinking and risk of SAH. These data suggest that heavy physical activity may trigger SAH.

“…Pressure, diet (e.g. high salt intake), hypertension, hyperglycemia, age and smoking can increase the risk of ICH [10][11][12][13][14]. In the present study, a majority of the patients were aged 50-70 years (66%).…”

This study was designed to compare the approaches and efficacies of two different ways of neurosurgical management for spontaneous putaminal hemorrhage (SPH): computed tomographic-guided aspiration (CTGA) and the key-hole approach (KHA). The indications of the two approaches are also explored. From September 2001 to 2003, a total of 1077 cases of SPH distributed in 135 hospitals all over the mainland of China were included for analysis. All cases had three-month follow-up data. The study was designed in a single-blinded manner to compare the efficacies of the different approaches. There were 563 cases in the CTGA group, 165 in the KHA group, and 217 cases in the conventional open craniotomy (COC) group. In the CTGA and KHA groups, the mortalities at one month after operation (M1m) were 17.9% and 18.3%, respectively, while the mortalities at three months after operation (M3m) were 19.4% and 19.4%, respectively (P>0.05). The postoperative complications due to CTGA (23.7%) were not significantly different from those due to KHA (25.7%) (P = 0.420). The M3m of patients with Glasgow coma scale (GCS) [Symbol: see text]8 was 3.45 and 4.0 times as much as those with GCS>8, respectively. The M3m of patients with complications was 3.92 times as much as those without complications. The M3m of patients with hemorrhage volume [Symbol: see text]70 mL was 2.67 times as much as those <70 mL. The CTGA is not better than KHA in the treatment of SPH in terms of a more favorable outcome or less mortality and morbidity, but CTGA could be the first choice for those with bleeding volumes ≤50mL, while KHA is the first choice for those with bleeding volumes >50 mL.

“…Physical activity, including sexual intercourse, has been identified as a potential external trigger for ICH with an increase in blood pressure as the major contributing factor [32]. The role of physical activity as a trigger for ICH is further supported by the marked reduction in the incidence of ICH at night, when people are usually sleeping [31].…”
