ABSTRACT

The purpose was to study in-flight blood pressure (BP) and heart rate (HR) in polar transport aviation pilots afflicted with essential hypertension. A total of 30 pilots were distributed into 2 groups: hypertensive pilots and those who, though generally healthy were, because of some conditions and lifestyle, predisposed to the cardiovascular risk (CVR). The examination included establishment of personal CVR factors, electrocardiography, bicycle ergometry, echocardiography, off-duty 24-hour BP and HR monitoring, and in-flight BP and HR monitoring. Maximum BP and HR values were higher in hypertensive pilots as compared with the control group. In the first group, maximum systolic BP (sBP) on the rise measured 202 mm Hg vs. 179 mm Hg in the control group. The highest HR on the rise was also registered in the first group (164 beats/min vs. 127 beats/min in the control). At landing, maximum sBP and HR made up 253 and 163 mm Hg, 150 and 141 beats/min values in groups first and second, respectively. To summarize, in the harsh weather conditions of Far North hypertensive pilots experience particularly heavy hemodynamic stresses during flight and, consequently, must be allowed to fly only if their hypertension is under control.

ABSTRACT

AIM: To study peculiar features of daily AP rhythm and profile in men with cardiovascular risk factors residing in the Far North. MATERIALS AND METHODS: The study included 115 servicemen divided into 3 groups (hypertensive disease (HD), hypertonic type neurocirculatory asthenia (NCA) and risk factor of cardiovascular diseases other than AH). HD was diagnosed based on multiple AP measurements and 24-hr monitoring. RESULTS: HD was associated with elevated mean AP, load indices and AP variability All patients had pathological type of morning dynamics. Normal daily rhythm of systolic AP (SAP) was documented in 66.1% of the patients with HD and in 68% with cardiovascular risk factors without AH. Normal daily rhythm ofdiastolic AP (DAP) was recorded in 63.5% of the patients with HD and in 72% with cardiovascular risk factors without AH. In group 2, normal daily rhythms of SAP and DAP were found in 44 and 56% of the cases respectively. CONCLUSION: Men residing in the Far North under conditions of anomalous photoperiod need medicamentous correction of AP regardless of AH type. Ambulatory BP monitoring should be preferred for the assessment of the efficacy of antihypertensive therapy.
