[Risks and benefits of spirometry in preoperative assessment for the surgical repair of abdominal aortic aneurysm].

Since 2019, spirometry is no longer contraindicated in patients with an aneurysm of the abdominal aorta (AAA). Lung function testing has therefore become a tool for the preoperative morbidity and mortality assessment of patients eligible for surgical repair of AAA. European guidelines of anesthesiology, vascular surgery and pneumology, recommend preoperative spirometry for polymorbide patients, for whom the preoperative assessment must be as complete as possible in order to improve perioperative management and to help specialists decide of the operative mode: open (for patients with a low-risk profile) or endovascular (preferred in high-risk profile patients).

[Seasonal variations of blood pressure in normal subjects and patients with chronic disease].

The characteristics and determining factors of seasonal variations of the blood pressure (BP) were studied in 20 normal subjects and 219 chronic stable chronically all patients, most of whom were ambulatory. The BP was measured repetitively over twelve months and measurements in the lying position repeated after one minute of orthostatism were performed in Winter and in Summer. In normal subjects, the BP decreased from June to reach its lowest value in August to return to the Winter values from October.

[Seasonal variations in arterial pressure in hypertensive patients].

Blood pressure (BP) was measured once every month during one year in 80 hypertensive outpatients. An orthostatic test was performed in winter and another during summer. The collective was aged 65 +/- 13 years (m +/- SD) and presented an elevated prevalence of diabetes mellitus, cardiac failure, and coronary, cerebral and arterial insufficiency.
