This study examined the prevalence of depression based on scores of 200 patients with acute coronary syndrome on the Emotion Profile Index of Plutchik and its relationship with the type of acute coronary syndrome and the severity of ischemic heart disease. Patients with acute coronary syndrome scored higher on depression than the control group. There was no difference in scores on Depression by type of acute coronary syndrome and no significant mean differences on Depression for patients with and without left ventricular failure. Patients with acute myocardial infarction and ventricular fibrillation scored lower on Depression than other patients with acute myocardial infarction and control group. This study supports the view that patients with acute myocardial infarction and ventricular fibrillation and lower scores on Depression have good prognosis during hospitalization and maybe for the long term.

Left ventricular end diastolic (LVEDP) and mean right atrial (RAP) pressures were recorded simultaneously in 30 patients with shock (14 acute myocardial infarction, 10 acute pulmonary embolism or severe bronchopulmonary disease, and 6 sepsis). Myocardial infarction was characterized by a predominant increase in LVEDP, pulmonary disease by a predominant increase in RAP, and sepsis by a normal relationship between LVEDP and RAP. In all three groups a significant positive correlation was noted between RAP and LVEDP, with the regression line in cor pulmonale deviated significantly toward the RAP axis and the regression line in myocardial infarction exhibiting a zero RAP intercept at an elevated LVEDP.Low cardiac outputs with elevated LVEDP in myocardial infarction indicated severe left ventricular failure. Low outputs with elevated RAP in cor pulmonale were consistent with right ventricular overload. Although cardiac outputs often were normal in sepsis, low outputs with elevated cardiac filling pressures in some patients were consistent with a hemodynamic or humoral-induced generalized depression of cardiac performance.Vasoconstrictor and inotropic drugs often produced a functional disparity between the two ventricles, with the gradient between LVEDP and RAP increasing, apparently because of an increase in left ventricular work or an inadequacy of left ventricular oxygen delivery. Acute plasma volume expansion with dextran in patients with pulmonary vascular disease resulted in a somewhat more rapid rise in RAP than in LVEDP. In septic and myocardial infarction shock, however, LVEDP and RAP usually rose proportionally, with the absolute rise of LVEDP surpassing that of RAP. Although the absolute level of the central venous pressure thus may not be a reliable indicator of left ventricular function in shock, changes in venous pressure during acute plasma volume expansion should serve as a fairly safe guide to changes in LVEDP.

This study examined the prevalence of major and minor depression in patients with acute coronary syndrome and their relation with heart rate and heart-rate variability, and clinical characteristics. The study group included 297 patients, 200 men and 97 women, between ages of 21 and 70 years (M age = 57.5 +/- 9.6), who were admitted to a coronary care unit with acute coronary syndrome and survived to discharge from the hospital. Major and minor depression were diagnosed using DSM-IV. There were 44.1% patients with acute coronary syndrome without depression, 29.3% with minor depression, and 26.6% with major depression. The prevalence of minor and major depression was more elevated in patients with non-ST-segment elevation myocardial infarction and unstable angina than in patients with ST-segment elevation myocardial infarction. Ventricular fibrillation and atrial fibrillation were more common in patients with major and minor depression than in patients without depression. The 24-hr. duration of heart-beat intervals and heart-rate variability were significantly lower in patients with major and minor depression than in patients without depression. This study implies that clinical depression was significantly comorbid with the acute coronary syndrome and was related to hypertension, diabetes mellitus, age, sex, type of acute coronary syndrome, left ventricular failure, higher heart rate, and lower heart-rate variability.

Chronic obstructive pulmonary disease (COPD) is associated with important extrapulmonary, or systemic, effects. There is systemic as well as pulmonary inflammation in COPD and this, together with systemic oxidative stress, contributes to their development. Skeletal muscle dysfunction contributes to exercise limitation. There is a loss of muscle mass and a reduction in the proportion of type 1 fibers. Sedentarism, hypoxia, corticosteroid therapy, nutritional depletion and systemic inflammation may contribute to its development. Weight loss is another important effect. It is associated with a worse prognosis, which changes with therapy and may be due to reductions in calorie intake, changes in intermediate metabolism and effects of systemic inflammation. Cardiovascular disease is a frequent cause of death in COPD and coronary artery disease, left ventricular failure and arrhythmias are systemic effects of COPD, as well as comorbidities sharing a common etiology. Exacerbations of COPD may increase the risk of coronary events by increasing the level of systemic inflammation. Osteoporosis is more common in COPD (even after adjusting for corticosteroid usage) and may be due to a combination of inactivity and the effects of systemic inflammation. COPD is also associated with systemic endothelial dysfunction and CNS abnormalities (including depression), which may also be due to the effects of systemic inflammation. These systemic effects respond to COPD treatments, including pulmonary rehabilitation, nutritional supplementation and inhaled corticosteroids, as well as specific drugs, such as bisphosphonates or diuretics. There is growing evidence that novel approaches, such as the use of statins, may also be of value.

Peripartum cardiomyopathy is an unusual form of dilated cardiomyopathy, which manifests as acute heart failure in the last trimester of pregnancy or early postpartum period. Its aetiology is currently unknown. The presenting signs and symptoms are those of congestive heart failure and more specifically those of left ventricular failure. Its importance lies in the fact that it has a high mortality rate and strikes the patient in the prime of life. Peripartum cardiomyopathy has far reaching implications for the anaesthesiologist. The reason for this is that many of the signs and symptoms of normal pregnancy are indistinguishable from mild cardiac failure so that the condition may remain undiagnosed and can present suddenly at the time of induction of anaesthesia or in the peri-operative period. The goals of anaesthetic management include avoidance of drug induced myocardial depression and prevention of increases in ventricular preload and afterload. Vigilant monitoring is essential throughout the surgery and in the postoperative period and the need for invasive monitoring should be assessed according to the clinical condition of the patient. It is important to recognise the association of cardiac failure and pregnancy as a separate syndrome so that peripartum cardiomyopathy can also be kept as a differential diagnosis for cardiac failure occurring in the peripartum period and a high index of suspicion should be maintained for the timely detection and management of this condition.
