Knowledge of a patient-dependant phase of acute myocardial infarction in Polish adults: the role of physician's advice.

BACKGROUND Effective management of acute myocardial infarction (AMI) is limited by patient delay in calling an ambulance. We aimed to assess knowledge related to a patient-dependant phase of AMI and its determinants in adults. METHODS Questionnaire survey was conducted among a random sample of 942 men (48%) and women (52%) aged 63.50 ± 6.50 selected from population registers in Cracow (Poland). Questions from the Behavioral Risk Factor Surveillance System were used to assess knowledge of AMI symptoms. The respondents were further asked about the first thing they would do in response to AMI symptoms, the emergency phone number and whether a doctor advised them about AMI. RESULTS All suggested AMI symptoms were recognized by 51 (5.4%) respondents. More persons would call an ambulance in response to AMI symptoms in another person than if they appear in themselves (87.4% vs. 74.4%, P = 0.02). Only 644 (68%) participants knew the emergency phone number and 104 (11%) were advised about AMI by their doctors. Such advice was associated with higher rates of knowledge of AMI symptoms and the emergency phone number but not with a declaration of the appropriate reaction to AMI symptoms. Participants after AMI did not represent better knowledge of a patient-dependant phase of AMI but paradoxically less frequently than other persons declared calling an ambulance in response to AMI symptoms. CONCLUSION Improvement in knowledge and attitudes related to a patient-dependant phase of AMI is needed in adults even if they experienced AMI before. A routine advice from a doctor may contribute significantly to this improvement.

The prevalence of abnormal echocardiographic findings in a sample of urban adult population

BACKGROUND Echocardiography has emerged as the test of choice for the evaluation of cardiac diseases. AIM To assess the prevalence of a spectrum of cardiac abnormalities detected by echocardiography in a representative sample of an urban adult population. METHODS Transthoracic echocardiography was performed in a random sample of 511 men (47%) and women (53%) aged 48-76 years selected from population registers in Krakow. Body surface area (BSA) was used to adjust echocardiographic parameters for variations in body size. Disease history and cardiovascular risk factors were assessed in all patients. RESULTS Men smoked more frequently than women and had higher blood pressure and triglycerides and lower high density lipoprotein cholesterol. The most common finding was increased left ventricular (LV) end-diastolic diameter (EDd) (37%), followed by mitral (32%), aortic (24%), or tricuspid (17%) regurgitations, LV posterior wall (24.1%) and interventricular septum (17.5%) thickening, increased indexed LVEDd (23%), increased left atrial diameter (LAd; 15.7%), reduced LV ejection fraction (LVEF; 15.3%), segmental wall motion abnormalities (13.9%), increased indexed LAd (8.8%), dilation of the ascending aorta (8%), enlargement of the right ventricle (RV) (2%) and elevation of RV systolic pressure (0.6%). When adjusted for main cardiovascular risk factors and the presence of coronary artery disease, male sex was associated with a higher prevalence of enlargement of LV (LVEDd/BSA): OR = 1.8 (1.1-2.9), dilation of ascending aorta (aortic diameter/BSA): OR = 2.7 (1.3-5.8), and LA (LA/BSA) = OR 2.7 (1.3-5.6), as well as a decrease of LVEF: OR = 3.6 (1.9-6.5). CONCLUSIONS Approximately a quarter of urban adults aged 48 to 76 can be expected to have some abnormalities on echocardiographic examination. Some of these abnormalities such as aortic dilation, LA enlargement, LV enlargement and decreased LVEF are more frequently found in males than in females, even after adjustment for BSA, main cardiovascular disease risk factors, and the presence of coronary artery disease. The use of raw instead of indexed LAd and LVEDd over estimates the prevalence of LA and LV enlargement.
