Seasonal distribution of acute myocardial infarction in the second National Registry of Myocardial Infarction.
OBJECTIVES This observational study sought to determine whether cases of acute myocardial infarction (AMI) reported to the second National Registry of Myocardial Infarction (NRMI-2) varied by season. BACKGROUND The existence of circadian variation in the onset of AMI is well established. Examination of this periodicity has led to new insights into pathophysiologic triggers of atherosclerotic ...
متن کاملSeasonal Distribution of Acute Myocardial Infarction in the Second National Registry of Myocardial Infarction 1
ion is accomplished through periodic review of hospital patient logs. As previously noted, registry hospitals may not be representative of all hospitals within the United States. Moreover, because this study is not population based but is based on the reporting of hospital-specific data, we are unable to sufficiently characterize the population at risk for AMI and how this population may vary b...
متن کاملSeasonal distribution of myocardial infarction and seasonal mood changes.
REPLY We thank Kok, Umans, and Arnold for their statistical calculations. Indeed, a large sample size would be required to prove that there is equivalence in clinical outcome between patients directly admitted compared to transferred patients. To demonstrate that the six-month mortality rate would not exceed more than 1% (6% vs. 7%) would require a sample size of even more than 25,000 patients!...
متن کاملRapid Diagnosis of Acute Myocardial Infarction
To improve the specificity of biochemical markers of myocardial infarction (MI) a method to measure cardiac troponin-I (CTn-I) was developed. CTn-I is a protein unique to cardiac muscle and is released after MI. Consecutive 150 patients admitted to the coronary care unit was studied. Value of CTn-I was determined in all samples. CTn-I concentration in the MI patients group was increased com...
متن کاملSeasonal distribution of acute myocardial infarction and its relation to acute infections in a mild climate.
BACKGROUND There is evidence that acute myocardial infraction (aMI) occurs more frequently in certain seasons and months of the year. Recently various infectious agents have been implicated in atherogenesis. In the present study we recorded the seasonal distribution of aMI and evaluated its relation to acute systemic infections (AIs). METHODS The study included 1196 patients with aMI hospital...
