Blood lipid changes in hypertensive, dyslipidemic patients under long term quinapril treatment.

OBJECTIVE: The present study aimed at verifying Quinapril effects on both pressure and lipid profile in 15 patients (5 M, 10 F), aged 45 to 80 years (63 +/- 9), complaining for mild to moderate hypertension and dyslipidemia (total cholesterol > 200 mg/dl and triglycerides > 200 mg/dl). No relevant associated disease was present, including diabetes mellitus not any lipid lowering drugs were given. METHOD: After a wash-out period of one week, all patients, who had been hypertensive for 2 to 120 months (33 +/- 11), were given Quinapril 20 mg orally once a day for 6 months and kept on a low lipid diet from before treatment to the end of the study. Lipid profile we assessed at three-month intervals. RESULTS: Blood pressure, monitored at two-week intervals, significantly decreased on the 1st month (p < 0.001), and kept lower thereafter. Mean total cholesterol, triglycerides and low density lipoprotein cholesterol levels, after 6 months of therapy, were reduced by 44 mg/dl (p < 0.001), 29 mg/dl (p < 0.001) and 39 mg/dl (p < 0.002) respectively. CONCLUSIONS: Our results seen indicate that Quinapril antihypertensive effects are accompanied by a significant improvement of the lipid profile.

[Cutaneous microcirculation in systemic sclerosis. Morpho-functional research using capillaroscopy and laser-Doppler].

Our previous researches proved that, in patients affected by Raynaud disease, microcirculatory alterations were greater in those cases in which the small vessels showed evocative appearances of a sclerodermatous connectivopathy. In this study we evaluated cutaneous microvasculature in 18 patients suffering from clear systemic sclerosis, compared with a group of 16 subjects affected by primitive Raynaud disease and a group of healthy subjects. We used videocapillaroscopy and laser-Doppler fluxmetry for morphological and functional study respectively. In patients affected by systemic sclerosis the rest flow was clearly reduced and morphological pattern of cutaneous small vessels deranged. The response to ischemic test allowed us to subdivide the skin-bounds in two subgroups: "no responders" 8 subjects (44%), in which reactive hyperaemia was completely absent, "responders" 10 patients (56%) in which the hyperaemia was completely overlapped with that of the two other groups, but with longer reaction times. In skinbounds the capillaroscopic pattern was clearly severe in comparison with other two groups (18.8 +/- 5.7 vs 5.7 +/- 2.3 and 3.6 +/- 1). Thus, in advanced stage of the pathology, is microangiopathy (in its tromboischemic and inflammatory aspects) that plays a very important role in the development of organ damage. Therefore, all those clinical and instrumental tests which may allow a differential early diagnosis between a primitive and a secondary Raynaud phenomenon be done, for its prognostic value in connection with the appearance of systemic sclerosis.

[Cutaneous microcirculation and diabetic disease. A functional and flowmetry study in subjects with diabetes mellitus type 2].

Laser-Doppler single fingertip skin blood flow has been evaluated in 41 euglycemic type II diabetic patients under basal conditions and after dynamic testing (both ischemia and thermal stress). The same subjects have also undergone tests for the assessment of the degree of autonomic nervous system (ANS) dysfunction. The results have been compared to those obtained in 38 age-matched healthy subjects. In diabetic patients: baseline flow levels were much higher; the post-ischemic flow increase was less evident; a shorter hyperemic phase followed ischemia; a longer latency period was noticed, during thermal stress, together with a lower and slower hyperemic peak level. According to the results of ANS dynamic tests, diabetic subjects were divided into 3 groups: Group 1 (subjects with negative results); Group 2 (subjects with only one positive result); Group 3 (subjects with more than one positive test). Microcirculation disturbances were more often found in Group 3. These results show that a correlation exists between diabetic microangiopathy and ANS dysfunction. They also support the hypothesis, already pointed out by other research groups, of a similar mechanism causing diabetic neurologic and vascular complications.

[Microcirculatory changes in mitral prolapse as an expression of a systemic change in the connective tissue].

Many authors hypothesize that mitral valve prolapse (MVP) can be, in most cases, only a clinical sign of a primitive and systemic disorder of the connective tissue, like in Marfan Syndrome (MS). In our previous works we supported the presence of morphological and functional alterations of the microcirculation in patients affected by MS. In order to characterize a possible common denominator between these pathologies we have studied the cutaneous microcirculation in a group of patients affected by MVP, divided into 2 groups: anatomic MVP (MVP) and MVP syndrome (MVPS). The morphologic parameters have been investigated by nailfold capillaroscopy while digital laser-Doppler was used to study skin flowmetry. The results have been compared with a control group. Capillaroscopic remarkers showed an architecturally disorganized microvasculature with aspects related to a reduced compactness of the microvasculature unit with a significatively higher score compared with controls (7.3 +/- 2.9 vs 3.6 +/- 1 p less than 0.0005). Laser-Doppler flowmetry showed a significatively reduced rest flow; ischemic test showed: spike time 48.9 +/- 36.9 vs 15.3 +/- 7.7 s (p less than 0.0005), hyperemic acme 6.6 +/- 2.7 vs 12.5 +/- 8.4 UP (p less than 0.002); % increase 32.1 +/- 20.2 vs 51.5 +/- 15.4 (p less than 0.002). Thermic test showed a significatively higher thermic acme 8.7 +/- 4.2 vs 12.6 +/- 9.11 UP (p less than 0.05). These results appeared to be correlated with stage pathology as it was observed a severe microvasculature disorders in MVPS. Therefore we suppose that a phenotypic continuum may exist between MS and MVP.

[The incidence and clinical significance of the echocardiographic finding of false chordae tendineae].

The presence of false tendons (FT) with M-mode and 2-D echocardiography in a consecutive series of 916 patients (520 men--396 women) with a wide age range (9-83 y) was investigated, and a possible correlation with heart systolic murmurs and/or heart arrhythmias evaluated. The problems that FT cause in differential diagnosis with other intraventricular structures were also considered. FT were observed in 53 subjects (5.8%), 30 men--23 women, and in an additional 51 cases (96%) in the left ventricular cavity. A clear prevalence of FT was observed during childhood and adolescence (26.1%), with the preferential location at the top of the ventricular chamber. No relevant correlation between FT and heart systolic murmurs and/or cardiac rhythm disorders was found. Although our results show that FT constitute an occasional finding, with no anatomic or functional relevance, they should always be held in due consideration in case of diagnostic uncertainty with other pathological structures, in particular intracavitary thrombi.

[False chordae tendineae: incidence and clinical meaning].

The presence of false tendons (FT) was sought with M-mode and 2-D echocardiography in a consecutive series of 316 patients with a wide age range (13-73 yrs). FT were observed in 13 patients (4.1%), all of them in the left ventricular cavity. Their clinical significance is pointed out together with the possibility of diagnostic error with other pathological formations, particularly intracavitary thrombi.
