The results of the physical analysis of circulation presented in this report are a further fragment of our research on the state of the circulatory system in the merchant marine officers over 40. 307 men were selected at random for the examinations, this constituting 13.5 per cent of the total population of the officers employed by the shipowner. Altogether the examinations covered 118 deck officers, 152 engine-room officers and 37 officers of the catering department. The parameters of the physical analysis of circulation were calculated according to Broemser-Ranke. The mean value of pulse wave velocity at the aorta was 833.63 +/- 155.41 cm/sec and in the radial artery--891.93 +/- 124.91 cm/sec for the whole examined population. The mean deformation resistance for all the examined was 1349.02 +/- 248.68 dyne/cm and the circumferential resistance--1347.55 +/- 347.89 sec. dyne/cm3. The mean systolic discharge for all the examined was 82.68 +/- 18.66 ml and the minute stroke volume 6.64 +/- 1.92 l/min. The mean work of the heart 1.20 +/- 0.38 J, the heart's power--1.60 +/- 0.59 W. The velocity of the discharge from the left ventricle was on average 17.66 +/- 3.44 l/min. For those parameters no statistically significant differences were found between particular groups of employment aboard. However, statistically significant differences were discovered in the calculations of the pulse wave velocity at the aorta. The differences were noticed between the group of clinically healthy men (771.52 +/- 114.71 cm/sec) on the one hand and the overweight group (854.39 +/- 116.34 cm/sec), the obese group (900.13 +/- 155.08 cm/sec), the group with ECG changes (925.01 +/- 193.24 cm/sec), the group with systolic and diastolic hypertension (acc to WHO criteria) (997.16 +/- 177.82 cm/sec), and in the group with hypertension accompanied by systolic discharge murmurs above the aorta (1113.38 +/- 127.24 cm/sec)--on the other. The pathological pulse wave velocity in the aorta (i.e. velocity of at least 9 m/sec) was found in 22.47% of the whole examined population.
本报告中呈现的循环系统物理分析结果，是我们对40岁以上商船船员循环系统状况研究的又一部分内容。随机挑选了307名男性进行检查，这占船东雇佣船员总数的13.5%。检查总共涵盖了118名甲板船员、152名机舱船员和37名餐饮部门船员。循环系统物理分析的参数是根据布勒姆泽-兰克方法计算得出的。整个受检人群中，主动脉处脉搏波速度的平均值为833.63±155.41厘米/秒，桡动脉处为891.93±124.91厘米/秒。所有受检者的平均抗变形能力为1349.02±248.68达因/厘米，周向阻力为1347.55±347.89秒·达因/立方厘米。所有受检者的平均收缩期射血量为82.68±18.66毫升，每分钟搏出量为6.64±1.92升/分钟。心脏的平均作功为1.20±0.38焦耳，心脏功率为1.60±0.59瓦。左心室射血速度平均为17.66±3.44升/分钟。在不同工作岗位的特定组之间，未发现这些参数有统计学上的显著差异。然而，在主动脉脉搏波速度的计算中发现了统计学上的显著差异。一方面，在临床健康男性组（771.52±114.71厘米/秒）与超重组（854.39±116.34厘米/秒）、肥胖组（900.13±155.08厘米/秒）、有心电图改变的组（925.01±193.24厘米/秒）、有收缩期和舒张期高血压（根据世界卫生组织标准）的组（997.16±177.82厘米/秒）以及有主动脉上方收缩期射血杂音伴高血压的组（1113.38±127.24厘米/秒）之间，发现了差异。在整个受检人群中，22.47%的人主动脉处出现病理性脉搏波速度（即速度至少为9米/秒）。
