The authors examine the clinical connotations of arterial hypertension in a geographical population of 1002 patients attending the Cardiological Outpatient Clinic of Unit no.2 in the Isonzo area (Monfalcone) using the most appropriate statistical methods, such as SPSS (Statistical Package for the Social Sciences) implemented on PC IBM AT 286, for multiple linear regression using a stepwise method. 1) Arterial hypertension was the result of a phenomenon which was striking owing to its mean value of 184.7 +/- 20.915 mmHg with equal mode and median of 180 mmHg. In the subgroup of 720 elderly patients this mean value differed slightly, 186.9 +/- 20.648 mmHg, with the same mode and median, whereas in the group of 282 adults the mean was 170.0 +/- 20.540 mmHg with a mode and median of 160 and 175 mmHg respectively. In the overall population 154 cases (15.4%) were affected by slight arterial hypertension with a mean of 158.9 mmHg, and 848 cases (84.8%) presented moderate-severe arterial hypertension with mean values of 189.4 mmHg. In elderly patients the mean rose to 190.4 mmHg whereas it was 186.3 mmHg in adults. 2) Mean age was 65.3 +/- 11.093 years: 70.7 +/- 7.396 years in older patients and 51.7 +/- 6.106 years in adults. Surface ECG showed signs of left ventricular hypertrophy in 292 elderly patients (40.5%) and 85 adults (30.0%), signs of ischemic cardiopathy due to T wave alteration in 246 elderly patients (34.1%) and 101 adults (35.7%), and due to ST tract in 340 (47.2%) and 102 (36.2%) respectively, with equal involvement of the free surface of the left ventricle. The radiographic enlargement of the cardiac shadow in elderly patients was observed in slight form in 153 cases (21.3%) and in moderate and marked form in 222 cases (30.8%), and in adults in 36 (12.8%) and 43 (15.2%) cases respectively. 3) Body weight was normal on average and equivalent to 77.3 +/- 13.578 kg, but of this series 713 cases were overweight and 237 were obese; 504 of elderly patients (70%) were pathological with 346 (48.1%) overweight and 158 (21.9%) obese, and of 209 pathological adults (74.1%), 130 (46.1%) and 79 (28.0%) were respectively overweight and obese. BMI oscillated from 1.70 to 5.60 with a mean of 2.80 +/- 0.409: from 1.70 to 4.21 in elderly patients with a mean of 2.70 +/- 0.379 and in adults from 2.00 to 5.60 with a mean of 2.90 +/- 0.460. 4) Mean cholesterolemia was 237 +/- 48.029 mg% and levels were normal in 203 cases and high in 799 subjects. Elderly patients showed the same mean level with a total of 580 pathological cases (80.5%) divided into 305 (42.3%) cases of slight hypercholesterolemia with a mean of 227.2 mg% and 275 (38.2%) severe cases with levels of 283.7 mg%. Adults presented a mean serum level of 236 +/- 47.588 mg%: 63 (22.3%) cases of normocholesterolemia, 117 (41.5%) cases of slight cholesterolemia with mean serum level of 224.8 mg%, and 102 (36.2%) severe cases with a mean level of 286.2 mg%, resulting in a total of 219 pathological cases (77.7%). |
