[Effects of rehabilitation on cardiovascular autonomic function in ischemic cardiopathy].

METHODS: Twenty patients with uncomplicated myocardial infarction randomized in two groups (group 1 and 2) of ten patients were investigated. Only group 1 trained four months according to a protocol of rehabilitation, whereas patients of group 2 followed their usual activity (control group). The autonomic cardiovascular function was estimated by Ewing's tests, that evaluate the variations of heart rate and blood pressure during deep breathing. RESULTS: Our data showed an increase of parasympathetic tone in group 1 (Valsalva ratio 1.55 +/- 0.28 vs 1.36 +/- 0.28, p < 0.01; variation in heart rate during deep breathing 17.3 +/- 4.6 vs 13.3 +/- 4.2). The sympathetic activity tests showed no significant difference after training. On the other hand, group 2 showed no significant difference in sympathetic and parasympathetic activity. CONCLUSIONS: In patients with uncomplicated myocardial infarction physical training increases the parasympathetic activity; as shown in the literature, such an increase can have clinical and prognostic importance, since improves cardiac performance and reduces the risk of sudden death from arrhythmic events.

Lipid-independent therapeutic properties of transdermal 17 B-estradiol on cardiovascular diseases.

A low dose of transdermally administered 17 B-estradiol promptly improved a severe, treatment-unresponsive, cardiac arrhythmia initiated after the menopause in a woman with type-II familial hyperlipoproteinemia. The same treatment normalized the hypertension initiated after ovariectomy, in a woman who was only poorly controlled by anti-hypertensive drugs. These two cases are the first clear report of cardiovascular therapeutic properties of transdermal estradiol via mechanisms independent of lipoprotein modifications.

[Usefulness of multicenter evaluation of the reliability of a program for automatic analysis in clinical electrocardiography].

The HP-5 program for computer analysis of the ECG has been evaluated as far as sensibility and specificity in a multicenter study. A consistent number of tracings were sampled according to a statistical formula and all measurements and statements given by the computer were checked in a standardized manner. The collected data were classified and computerized. The HP-5 program has shown a very high specificity for tracings classified as normal (0.7% of false negatives) and for those classified abnormal (no false positive), while the level of agreement between manual and computer readings of the tracings classified atypical or borderline, was fair (75%). It is concluded that the new program represents a significant step forward in the practical use of computerized ECG.

[Comparative evaluations between on-line and off-line in automatic electrocardiographic diagnosis and readings of the cardiologist].

The comparative evaluation of diagnosis, given on the same ECG by a cardiologist and by a computerized system HP 5600 C on line and off line, allowed us to specify for each diagnosis the agreement's degree between cardiologist and computerized reading and the disagreement's degree due to inadequate program and to "casual" errors of analysis.

[Multicenter study and clinical use of HP-5 program (author's transl)].

The HP-5 program for computer analysis of the ECG has been evaluated as far as sensibility and specificity in a multicenter study. A consistent number of tracings (850) were sampled according to a statistical formula and all measurements and statements given by the computer were checked in a standardized manner. The collected data were classified and computerized. The HP-5 program has shown a very high specificity for tracings classified as normal (0.7% of false negatives) and for those classified abnormal (no false positive), while the level of agreement between manual and computer readings of the tracings classified atypical or borderline, was practical of computerized ECG.
