Assessment of knowledge on cardiovascular disease risk factors by postal survey in residents of Malopolska Voivodeship. Malopolska CArdiovascular PReventive Intervention Study (M-CAPRI).

[b]Introduction.[/b] Education is a key tool in the prevention of cardiovascular disease (CVD). Education programmes require monitoring of their effectiveness. [b]Objectives. [/b]1) to introduce postal screening for the assessment of knowledge on CVD risk factors (RFs) for the Polish population, 2) to assess this knowledge in adult residents of Malopolska Voivodeship, and 3) to assess whether knowledge on RFs is related to age, gender, place of residence, level of education and family history of CVD. [b]Materials and method.[/b] Anonymous questionnaires were posted to a random sample of 5,000 residents of Malopolska Voivodeship in Poland. Results were presented as proportions of participants who listed RFs correctly. A series of multiple logistic regression models was used to assess the associations of knowledge on RFs with the potential determinants. [b]Results.[/b] 1,126 completed questionnaires were returned. Over 35% of respondents could not list a single RF and 14 % listed only 1-2 RFs. About 40% named 3-5 and only 12% listed 6 or more RFs. About a half of the respondents listed incorrectly from 1-8 characteristics as being associated with higher risk of CVD. In the multivariate analysis, knowledge on RFs was not significantly associated with age. Level of education was the strongest determinant of knowledge. Male rural and small town residents had less knowledge, whereas women with a family history of CVD had more knowledge on some CVD RFs. [b]Conclusions.[/b] Using a postal questionnaire for the assessment of knowledge of CVD RFs in the population of Malopolska Voivodeship appeared to have serious limitations due to low participation in the study. Despite this, the results of the study indicate that knowledge on CVD RFs is insufficient. Female gender and higher education were related to more prevalent knowledge on RFs. Family history of CVD was related to better knowledge in women only. Male residents of rural areas and small towns had slightly less knowledge on CVD RFs.

Effectiveness of single medical advice on emergency phone number knowledge in urban adult population--"Health, Alcohol and Psychosocial Factors in Eastern Europe" substudy.

INTRODUCTION: Early access to Emergency Medical Services determines survival in out-of-hospital cardiac arrest. However, a significant proportion of adults do not know the emergency phone number (EN) and no intervention has been proposed to improve it. Therefore, we aimed to assess prospectively the effectiveness of single advice from a physician on knowledge of the EN in adult population. MATERIALS AND METHODS: The study was conducted among participants of "Health, Alcohol and Psychosocial Factors in Eastern Europe" study. A total of 942 persons (aged 48-82 years) randomly selected from an urban population registry were interviewed and then instructed about the correct EN (the intervention group). After 12 months knowledge of the EN was assessed in the intervention group (n=716) and in matched control group (n=435). RESULTS: The correct EN was given by 498 (69.6%) participants at baseline and in 550 (76.8%) participants 12 months afterwards (p<0.001). At follow-up the knowledge of EN was higher by in intervention group than in controls (76.8% vs 70.6%, p=0.02). Factors associated with better educational effect were male sex (OR 1.49; 95% CI 1.04-2.1) and secondary or higher level of education (OR 1.44; 95% CI 1.08-1.91). CONCLUSIONS: We concluded that a single instruction about the EN from a physician increases its long-term knowledge and should be offered during medical visits.

A patient with acute aortic dissection presenting with bilateral stroke - A rare experience.

Acute aortic dissection is a rare, life-threatening condition requiring early recognition and proper treatment. Although chest pain remains the most frequent initial symptom, clinical manifestation of aortic dissection varies. Rarely aortic dissection starts with neurological symptoms such as ischemic stroke, which is usually right-sided. A danger of performing thrombolytic therapy in these patients exists if aortic dissection is overlooked. Herein, we present a case of a patient with acute aortic dissection without typical chest pain whose initial manifestation was bilateral stroke. The uncommon presentation which masked the underlying condition delayed implementation of appropriate management. Moreover, the late admission to hospital prevented the patient from administration of recombined tissue plasminogen activator that would certainly decrease chances of survival. Presented case highlights the need for thorough physical examination at admission to hospital in all patients with acute stroke and points out the necessity of proper clinical work-up including adequate aorta imaging modalities of patients with acute stroke and suggestive findings of aortic dissection.

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.

Electrocardiogram for the diagnosis of right ventricular hypertrophy and dilation in idiopathic pulmonary arterial hypertension.

BACKGROUND: Currently, there are no data on the association between right ventricular (RV) structure and ECG changes specific for idiopathic pulmonary arterial hypertension (IPAH). Therefore, we aimed to assess the accuracy of the recommended ECG criteria for predicting RV hypertrophy (RVH) and dilation in patients with IPAH. METHODS AND RESULTS: Twelve-lead ECG and cardiovascular magnetic resonance imaging (CMR) were performed in 23 consecutive patients with IPAH aged 49.8±16.3 years. ECG criteria were referred to RV mass index and RV end-diastolic volume index as measured by CMR. Only the ECG voltage criteria based on R wave amplitude in lead V1, R wave amplitude in aVR, P wave amplitude in II and ventricular activation time in V1 were useful for differentiating between patients with and without RVH. A ventricular activation time in lead V1 of <0.01 s excluded RVH, whereas R in V1 >6 mm, R:S in V1 >1, R in aVR >4 mm, R:S in V5 to R:S in V1 <0.04 and P in II >2.5 mm confirmed the diagnosis. Only the ventricular activation time in V1 correlated with RV dilation and when >0.045s confirmed its diagnosis. CONCLUSIONS: Only a few of the recommended ECG criteria proved to be useful in the diagnosis of RVH or RV dilation in patients with IPAH. Changes in the cut-off values improved their accuracy.
