It is well-established that acute coronary syndromes occurs when thrombus formation from atheromatous plaques erode or rupture in the advanced stage of atherosclerotic process with severe reduction of coronary blood flow. Also, some conditions may trigger acute coronary syndrome even in the absence of prior cardiovascular disease, and with normal coronary vessels. One of the most important is Kounis syndrome, also known as allergic angina or allergic myocardial infarction in which the release of mediators during allergic insults has been incriminated to induce coronary artery spasm and/or atheromatous plaque erosion or rupture. The accurate incidence of Kounis syndrome is not known, but since it was described, many clinical cases have been reported, showing the occurence due to various allergens. Here we present two cases of most probable Kounis syndrome, first in patients after multiple stings by non-venomous insect called black-fly.

Acute myocardial infarction as a form of coronary heart disease is characterized by permanent damage/loss of anatomical and functional cardiac tissue. Diagnosis of STEMI includes data on anginal pain and persistent ST-segment elavation. According to the numerous epidemiological studies, arterial blood pressure and heart rate are offten increased especially during the first hours of pain due to domination of sympathetic response. We wanted to investigate the associated influence of heart rate greater than 80 beats per minute and hypertension on the mortality in patients with anterior wall STEMI. Research included 140 patients treated in Coronary Unit, Clinical Center Kragujevac form January 2001 to June 2006. Heart rate was calculated as the mean value of baseline and heart rate in the first 30 minutes after admission, recorded on monitor and electrocardiogram. Data for history of hypertension were collected and blood pressure levels were measured in a lying position after 5 minutes of rest, and classified according to the VII JNC recommendations as confirmation of hypertension. Collected data were analyzed in SPSS 13.0 for Windows. Heart rate greater than 80 bpm influences the hospital mortality. Systolic blood pressure levels were higher in the survivors, while for the diastolic there was no difference. History of hypertension was singled out as a significant predictor of mortality without difference between the respondents with heart rate greater and lower than 80 bpm in the survivors and fatal. Increased heart rate and hypertension at admission are significant predictors of mortality in patients with anterior wall STEMI.
