[The diagnosis of the cardiologic risk in patients destined for lung removal surgery].

The expanding role of pulmonary surgery could be expected to lead to an increase in postoperative morbidity and mortality unless surgical risk factors are identified by means of a careful preoperative assessment. A careful and intelligent preoperative evaluation can reduce the morbidity and mortality after lung resection by ensuring the appropriate selection of patients and a rational choice of operative procedure. To evaluate the cardiologic risk in patients undergoing lung resection, 18 of them underwent a diagnostic protocol based on non invasive analysis including ECG, stress test with basal and exercise blood gas analysis, M- and B-mode and Doppler echocardiography. This protocol was able to identify possible cardiologic risk in the perioperative period without applying invasive techniques and with a good cost-benefits ratio.

[Behavior of systolic blood pressure during recovery phase after bicycle ergometric test. Its value in the diagnosis of ischemic heart disease].

The diagnostic utility of an abnormal decrease in systolic blood pressure (PAS) after exercise, have been evaluated by an index obtained by the ratio between PAS at the maximal stage of exercise and PAS at the 1', 3' and 5' of recovery (PAS index). The 58 patients studied have been divided in two groups: group A, 32 patients, aged 33-66 (means 51.5) with angina pectoris and significant coronary stenosis; group B, 26 subjects, aged 27-39 (mean 34.7), asymptomatic, without coronary stenosis (control group). PAS index at 1' of recovery have been 0.82 +/- 0.08 in the group B and 0.94 +/- 0.07 in the group A (p less than 0.0005); at the 3' of recovery 0.72 +/- 0.07 in the group B and 0.86 +/- 0.11 in CAD group (p less than 0.0005); at 5' of recovery 0.66 +/- 0.07 in the group B and 0.79 +/- 0.11 in the group A (p less than 0.0005). Diagnostic accuracy have been of 60%, 75% and 75% for PAS index respectively at first, third and fifth minute of recovery, while ST depression diagnostic accuracy have been of 88%.

[Myocardial infarct without Q wave in the elderly: diagnostic evaluation using vectorcardiography].

The diagnosis of previous non-Q wave myocardial infarction by standard electrocardiographic investigation is uncertain, particularly in elderly patients because of concomitant disease. We have studied 31 elderly patients (aged 63-72 years) with a diagnosis of non-Q wave myocardial infarction between 1-6 months after this acute event. The patients underwent clinical-anamnestic examination, standard electrocardiography, vectorcardiography according to the Frank system and M-mode and 2-D echo-cardiography with continuous and pulsated Doppler. The ECG showed ST-T anomalies in 12 patients (38.7%) whereas the VCG showed anomalies of QRS-loop normal convexity in 27 patients (87%) and 16 of these (51.6%) showed bites criteria (duration > or = 10 msec, voltage > or = 0.1 mV, present at least on two planes). By echocardiography, regional hypo-akinesia was observed in 19 patients (61.3%). Although bites are not only present in myocardial infarction, they indicate an interruption of myocardial gradual electric activation, compatible with fibrous areas, and should be evaluated as a part of the clinical-anamnestic, laboratory and instrumental data.
