The antithrombin III (AT III) activity and the AT III concentration were investigated in 62 consecutive patients with acute myocardial infarction (AMI). To identify the reactant pattern of AT III in postaggressive situations, we also determined labile and acute phase proteins. Firstly, 29 patients were nourished orally and then 33 patients were fed by i.v. hyperalimentation (additional caloric intake of approximately 1,000 cal). AT III activities and concentrations as well as prealbumin and retinol-binding protein decreased concomittantly and significantly whereas haptoglobin, C-reactive protein and fibrinogen increased significantly after AMI. The changes cannot be interpreted as being alterations of the haematocrit. The alterations of AT III correlated significantly with the changes of labile proteins but not with the acute phase reactant proteins. The AT III decrease in the postinfarctional phase may promote a prethrombotic state. In In addition it can be concluded from our results that AT III reacts as (nutritive-dependent) labile protein, which is lowered in postaggressive situation and does not increase as an acute phase reactant. This is in accordance with results from recent animal experiments.

A 61-year-old woman with profound hypothyroidism underwent surgery for a ventricular septal perforation 15 days following an acute myocardial infarction, with no preoperative thyroid replacement. Her immediate postoperative course was complicated by a low cardiac output, respiratory suppression and high output renal failure, requiring prolonged hemodynamic and respiratory support. Thyroid replacement (50 micrograms of thyronine and 100 micrograms of thyroxine daily) was given in two installments on the 2nd day after the operation. The effect of the inotropic agents increased gradually and the patient was weaned off intra-aortic balloon pumping. A large quantity of diuretics, hydration and hyperalimentation also successfully reduced her elevated BUN and serum creatinine. After full thyroid replacement, she was discharged in good health on the 40th postoperative day.

Previous analyses have suggested that factors that stimulate the sympathetic nervous system and catecholamine release can trigger acute myocardial infarction. The wake-up time, Mondays, winter season, physical exertion, emotional upset, overeating, lack of sleep, cocaine, marijuana, anger, and sexual activity are some of the more common triggers. Certain natural disasters such as earthquakes and blizzards have also been associated with an increase in cardiac events. Certain unnatural triggers may play a role including the Holiday season. Holiday season cardiac events peak on Christmas and New Year. A number of hypotheses have been raised to explain the increase in cardiac events during the holidays, including overeating, excessive use of salt and alcohol, exposure to particulates, from fireplaces, a delay in seeking medical help, anxiety or depression related to the holidays, and poorer staffing of health care facilities at this time. War has been associated with an increase in cardiac events. Data regarding an increase in cardiac events during the 9/11 terrorist attack have been mixed. Understanding the cause of cardiovascular triggers will help in developing potential therapies.

Physiologic and clinical triggers, including mental stress, anxiety, and anger, often precipitate acute myocardial infarction and cardiovascular death. Sporting events can acutely increase cardiovascular event and death rates. A greater impact is observed in patients with known coronary artery disease and when stressful features are present, including a passionate fan, a high-stakes game, a high-intensity game, a loss, and a loss played at home. Sporting events affect cardiovascular health through neuroendocrine responses and possibly an increase in high-risk behaviors. Acute mental stress increases the activity of the hypothalamic-pituitary-adrenocortical axis and the sympathetic-adrenal-medullary system while impairing vagal tone and endothelial function. Collectively, these mechanisms increase myocardial oxygen demand and decrease myocardial oxygen supply while also increasing the risk of arrhythmias and thrombosis. Measures can be taken to reduce cardiovascular risk, including the use of beta-blockers and aspirin, stress management, transcendental meditation, and avoidance of high-risk activities, such as smoking, eating fatty foods, overeating, and abusing alcohol and illicit drugs. Sporting events have the potential to adversely affect spectators' cardiovascular health, and protective measures should be considered.
