.We evaluated the circulating levels of brain natriuretic peptide (BNP) in stable angina, unstable angina, and myocardial infarction relating hormone levels to extension of coronary disease and number of vessels involved after angiographic examination. We studied 86 patients consecutively undergoing angiographic coronary examination and echocardiographic evaluation for coronary heart disease. These included 15 control subjects (group 0), 21 with stable angina (group I), 26 with unstable angina (group II), and 24 with non-Q myocardial infarction (group III). Patients with heart failure, a history of myocardial infarction, or recent myocardial damage with electrocardiographic S-T elevation were excluded. BNP levels in patients with unstable angina and myocardial infarction were significantly increased with respect to the group with stable angina (P<0.01). There were no differences between the groups with unstable angina and myocardial infarction. Analysis of peptide levels in relation to the number of involved vessels demonstrated a significant increase in patients with three-vessel disease compared with subjects with one or two vessels involved (P<0.03); among subjects with mono-vessel disease, patients with left descendent anterior stenosis had a more-marked BNP elevation than subjects with stenosis in other regions (P<0.01). Hence, BNP levels appear to be elevated in coronary disease, especially in acute coronary syndromes, even in the absence of systolic dysfunction. BNP levels also seem to be related to the severity of coronary atherosclerosis and number of vessels involved. BNP could prove a novel marker for risk stratification, not only in heart failure but also in coronary heart disease.

Abstract

.We evaluated the circulating levels of brain natriuretic peptide (BNP) in stable angina, unstable angina, and myocardial infarction relating hormone levels to extension of coronary disease and number of vessels involved after angiographic examination. We studied 86 patients consecutively undergoing angiographic coronary examination and echocardiographic evaluation for coronary heart disease. These included 15 control subjects (group 0), 21 with stable angina (group I), 26 with unstable angina (group II), and 24 with non-Q myocardial infarction (group III). Patients with heart failure, a history of myocardial infarction, or recent myocardial damage with electrocardiographic S-T elevation were excluded. BNP levels in patients with unstable angina and myocardial infarction were significantly increased with respect to the group with stable angina (P<0.01). There were no differences between the groups with unstable angina and myocardial infarction. Analysis of peptide levels in relation to the number of involved vessels demonstrated a significant increase in patients with three-vessel disease compared with subjects with one or two vessels involved (P<0.03); among subjects with mono-vessel disease, patients with left descendent anterior stenosis had a more-marked BNP elevation than subjects with stenosis in other regions (P<0.01). Hence, BNP levels appear to be elevated in coronary disease, especially in acute coronary syndromes, even in the absence of systolic dysfunction. BNP levels also seem to be related to the severity of coronary atherosclerosis and number of vessels involved. BNP could prove a novel marker for risk stratification, not only in heart failure but also in coronary heart disease.
