[Blood viscosity in ischemic heart disease].

Through a capillary viscometer we measured venous and arterial blood viscosity (BV) in 25 patients with the diagnosis of ischemic heart disease (IHD); 10 of them with unstable angor pectoris (UA) and 15 with acute myocardial infarction (MI). The control group consisted of 100 normal individuals in whom the normal values were 2.70 +/- 0.10 centipoises, where as in patients with AU the values were 4.03 +/- 1.40 centipoises and in the group with MI was 3.65 +/- 1.20 centipoises. Statistically, we correlated the BV obtained in both groups with the following parameters: coronary risk factors, cell blood count; serum glucose, cholesterol and triglycerides as well as the number of coronary arteries involved. The levels of venous and arterial BV were elevated in both groups of patients in comparison with the control group. We concluded that arterial and venous BV is elevated in patients with IHD independently of the hematocrit. This suggest the probability of some other factors such as plasmatic viscosity and platelets aggregation could play a role in the BV elevation of this group of patients.

[Permanent pacemakers: 15 years' experience].

We report a 15 year experience in the attention of patients with definitive pacemakers. This study includes 200 patients treated from 1964 to 1978, with an age range from 15 to 102 years, who required 329 generators. The predominant cardiopathy was atheroesclerotic (172 cases). We analyze the associated diseases in which hypertension was prominent in 30% of these cases. The most frequent rhythm alteration was atrioventricular block in 72% of the cases, and trifascicular block in 16%. We observed 35 intercurrent complications (17.5%), and the most frequent was infection of the generator bag. Mortality in these patients averaged 11%, being strictly imputable to the pacemaker in only 2%. Eighty patients needed generator change and we report a case who required up to six changes. The implantation of permanent pacemakers for treatment of patients with severe arrhythmias is considered at present secure and effective.
