Relative prognostic value of clinical, biochemical, echocardiographic and haemodynamic variables in predicting in-hospital and one-year cardiac mortality after acute myocardial infarction.

This study examined the relative value of clinical, biochemical, echocardiographic and haemodynamic variables, obtained early after acute myocardial infarction in predicting in-hospital and one-year cardiac mortality in 66 consecutive patients. Clinical examination and cross-section echocardiography were obtained in all 66 patients. An echocardiographic score index was calculated by grading wall motion from 0 to 5 in each of 16 left ventricular segments. Right-sided cardiac catheterization was performed soon after admission in 51 patients. Cardiac enzymes were measured every fourth hour in all patients and peak levels were identified in 55. During the follow-up of one year, 14 patients died of cardiac causes, seven of them during hospital stay; three patients died of a non-cardiac cause and were excluded from analysis. The echocardiographic score index was the best predictor of cardiac death and survival (chi 2 = 35), followed by Killip class on admission (chi 2 = 22), stroke volume index (chi 2 = 17) and a biochemical risk index (chi 2 = 11). Stepwise logistic discriminant analysis performed in the patients in whom all variables were obtained resulted in three independent prognostic variables: the echocardiographic score index, systemic vascular resistance at the time of catheterization and the development of infarct expansion. High- and low-risk patients are well identified by echocardiography in the acute phase of myocardial infarction.

Haemodynamic alterations during ischaemia induced by dobutamine stress testing.

To identify the haemodynamic response to ischaemia induced by dobutamine stress testing, 15 patients with a first acute myocardial infarction underwent right-sided heart catheterization during dobutamine stress cross-sectional echocardiography. Haemodynamic variables and echocardiography were recorded at rest and during dobutamine infusion at each dose from 5 to a maximum of 40 micrograms kg-1 min-1. Ischaemia was diagnosed by cross-sectional echocardiography if asynergy appeared in at least two ventricular segments other than the area of acute myocardial infarction. Ischaemia was absent in six patients (group I) and identified in nine (group II). Response curves for each haemodynamic variable in the two groups were compared by applying Zerbe's method. The response curves were similar in the two groups for heart rate, arterial, right atrial, pulmonary arterial and pulmonary artery wedge pressures. The response curves were significantly different in groups I and II for thermodilution cardiac output, stroke volume and systemic vascular resistance (P less than 0.05). An increase in stroke volume was observed at low dosage of dobutamine in both groups. From low to maximum dose, stroke volume remained unchanged in group I and was significantly decreased in group II. Ischaemia induced by dobutamine stress testing leads to a decrease in stroke volume with no change in pulmonary artery wedge pressure.

Long-term prognostic significance of atrioventricular block in inferior acute myocardial infarction.

Among 477 consecutive patients admitted for inferior acute myocardial infarction (AMI), 2nd or 3rd degree atrioventricular (AV) block developed in 88 (20%). Compared with the 359 without AV block, these 88 patients presented a higher incidence of Killip class greater than 1 (52% vs 28%, P less than 0.001), pericarditis (30% vs 17%, P less than 0.01), atrial fibrillation (26% vs 11%, P less than 0.01), complete bundle branch block (12% vs 4%, P less than 0.01) and in-hospital mortality (24% vs 4%, P less than 0.001). The 3-year post-hospital mortality was not significantly different in the two groups (12% vs 15%). Among the 88 patients with AV block, those who died at hospital were older (66 +/- 11 vs 59 +/- 11 years, P less than 0.05), had a higher incidence of Killip class greater than 1 (86% vs 42%, P less than 0.001) and bundle branch block (29% vs 7%, P less than 0.05). Thus, patients with inferior AMI who developed AV block had a poor hospital outcome but long-term prognosis was similar in hospital survivors who had AV block and in those without this complication.

[The role of plasma alpha 1-glycoprotein acid in the binding of aminopyrine].

Under certain pathological conditions the binding of various substances by serum proteins is altered. The plasma concentrations of alpha 1-acid glycoprotein, also known as orosomucoid are reported to be elevated in stressful situation and in certain disease states like acute myocardial infarction. The binding of aminopyrine to serum proteins and alpha 1-acid glycoprotein was determined using equilibrium dialysis. It appears that alpha 1-acid glycoprotein has specific binding sites for aminopyrine. Aminopyrine was also bound to other serum proteins. On addition the results indicate that an increase of alpha 1-acid glycoprotein to concentrations such as those seen in some pathological states does not really alter the percent of aminopyrine bind to serum proteins.

The pattern of food and mortality in Belgium.

Belgians have been gradually shifting from a low ratio of polyunsaturated/saturated fat in their food to a higher one with lower total fat and cholesterol. This has occurred predominantly in the north, where the most obvious change is a decrease in butter consumption and an increase in margarine consumption. The northerners have a four to five times smaller intake of butter than the southerners and nearly double the intake of margarine. Evidence gathered over the past ten years reveals in the north a decreasing serum-cholesterol and in the south a significantly higher serum-cholesterol, associated with higher coronary morbidity and mortality. Life expectancy of males in the north is 2-4 years higher at birth and 2-2 years higher at the age of 30. It is concluded that the food habits of a population can be changed, with great benefit.
