Diagnosis and management of atrial fibrillation by primary care physicians in Italy : a retrospective, observational analysis.

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with a heavy burden of morbidity and mortality, mainly due to an increased risk of cerebrovascular events and cardiac failure. Oral anticoagulant (OAC) treatment prevents stroke and systemic thromboembolism in patients with AF and its use is strongly recommended in guidelines. However, its use in this patient group remains limited. Primary care physicians (PCPs) have an important role to play in this context. OBJECTIVE: The primary objective was to estimate prevalence and epidemiological features of AF in the primary care setting, focusing on ischaemic and bleeding risk assessment. A secondary objective was to examine the PCPs' level of adherence to the guidelines for the prevention of thromboembolic risk in these patients. METHODS: This retrospective, observational study was based on data entered by 128 PCPs into the Health Search (HS) Thales database, identifying patients with a diagnosis of AF at the time of the analysis. RESULTS: Out of 167,056 patients analysed, 2,173 (1.3 %) were diagnosed with AF, with 86 % at high risk for ischaemic stroke, according to CHA(2)DS(2)-VASc (congestive heart failure, hypertension, age ≥75 years [doubled], diabetes, stroke [doubled], vascular disease, age 65-74 years, sex category [female]) stratification. After the diagnosis of AF, 84 % of patients were prescribed OAC treatment. However, at 2 years' follow-up, only 29.6 % were still being treated with OACs. CONCLUSION: The prevalence of AF in this analysis was consistent with previously reported Italian national epidemiological data. Adherence to the European Society of Cardiology AF guidelines by PCPs was low, despite the high levels of stroke risk. At the end of the observation period less than one-third of patients were still on OAC therapy. Awareness of the benefits of OACs in stroke prevention in AF patients needs to be improved.

Knowledge of cardiovascular risk factors and awareness of non-pharmacological approach for risk prevention in young survivors of acute myocardial infarction. The cardiovascular risk prevention project "Help Your Heart Stay Young".

BACKGROUND AND AIMS: Knowledge of cardiovascular disease (CVD) risk factors in young patients who experienced myocardial infarction (MI) is poorly described. METHODS AND RESULTS: Knowledge of traditional CVD risk factors, non-fatal cardiovascular events and of non-pharmacological factors able to reduce CVD risk and education level were evaluated by questionnaires in subjects who visited their family doctors. Sixty-one participants with history of MI in age <50 years (MI+) were compared with 3749 subjects with age <50 years, from the same population source, but without history of MI (MI-). MI+ were more frequently men (p<0.01), did not have significantly higher prevalences of family history of CVD, diabetes and hypertension. MI+ individuals reported previous non-fatal stroke (13% vs. 0.5%, p<0.001), overweight, diabetes, and hypercholesterolemia (all p<0.001) more frequently than controls, whereas prevalence of arterial hypertension, smoking habit and physical inactivity did not differ between the two groups; MI+ and MI- individuals did not differ in terms of the proportion of those who were unaware of being hypertensive, diabetic or hypercholesterolemic. MI+ participants reported more frequently lower education level than controls (p<0.05). Knowledge of non-pharmacological approach for CVD risk reduction was similar in MI+ and MI-. In a logistic multivariate analysis, male gender (adjusted odds ratio=5.8) and high cholesterol level (adjusted odds ratio 2.8, both p<0.01) were independent correlates of MI+. CVD risk factors distribution was similar between participants with juvenile MI+ and MI in age >or=50 years (n=167) extracted from the same population source; however, stroke was reported more frequently in juvenile MI+ than in those who had MI at age >or=50 years/old (13% vs. 4%, p<0.01). CONCLUSIONS: Juvenile non-fatal MI was associated with metabolic CVD risk factors, with higher cerebrovascular co-morbidity and lower education level.

Individuals' cardiovascular risk profile projected by family doctors and individuals' knowledge of cardiovascular risk factors: a challenge for primary prevention. The cardiovascular risk prevention project "Help Your Heart Stay Young".

BACKGROUND: Whether the practice of family doctors of assessing individuals' cardiovascular risk profile improves individuals' knowledge of risk factors in primary prevention has not been established. Accordingly, we evaluated patients' knowledge of cardiovascular risk factors and lifestyle in healthy subjects whose family doctors provided individual cardiovascular risk score. METHODS: Subjects who visited their family doctor in a time frame of 3 months, who accepted to fill-in a simple questionnaire measuring their knowledge of cardiovascular risk factors and of non-pharmacological interventions able to reduce cardiovascular risk were evaluated. RESULTS: Fifty-one family doctors were involved. The study sample comprised 4239 subjects (mean age 56 +/- 9 years, 62% women) in primary prevention. They were classified by their family doctors, based on the Framingham algorithm, as being at low (< 10%; 45.7% of subjects), medium (10-20%; 38.7% of subjects) or moderate-to-high (> 20%; 15.6% of subjects) cardiovascular risk. The prevalence of obese subjects (40, 48, and 49%, respectively) and of heavy smokers (> or = 20 cigarettes/day; 26, 30, and 34%) increased from the low to the moderate-to-high risk group (both p < 0.05). The proportion of subjects unaware of personal history of arterial hypertension (5, 6, and 9%) and that of subjects who were unaware of history of elevated cholesterol levels (10, 11, and 12%, both p < 0.01) increased with higher cardiovascular risk score. The proportion of subjects self-reporting blood pressure > 135/85 mmHg, but self-reporting being normotensive (30, 50, and 52%), and the proportion of subjects who referred cholesterol levels > 200 mg/dl among those who self-referred not to have elevated cholesterol levels (13, 25, and 31%) increased both with cardiovascular risk category (p < 0.001). The proportion of subjects who were unaware of their personal history of diabetes was similar in the cardiovascular risk groups. The prevalence of low educational level was higher (56, 58, and 62%, p < 0.01) and the level of knowledge of non-pharmacological remedies to cardiovascular risk factors (63, 61, and 59%, p < 0.01) was lower in higher cardiovascular risk score group. Subjects aged < 55 years showed similar lack of knowledge about cardiovascular risk factors and the proportion of heavy smoking was as high as in the group of older participants. CONCLUSIONS: In cardiovascular primary prevention, the projection of higher individuals' risk profile by family doctors was not paralleled by an increase in individual's knowledge of major cardiovascular risk factors and of lifestyle interventions able to reduce the cardiovascular risk.

Cardiovascular secondary prevention: patients' knowledge of cardiovascular risk factors and their attitude to reduce the risk burden, and the practice of family doctors. The "Help Your Heart Stay Young" study.

BACKGROUND: Whether the practice of family doctors of assessing the global cardiovascular risk profile improves the knowledge of cardiovascular risk factors and the attitude to lifestyle change in patients' secondary cardiovascular prevention is unknown. METHODS: We evaluated subjects who visited their family doctors and those with self-reported cardiovascular disease in the urban area of Naples, Italy. Patients self-administered a simple standard questionnaire to evaluate their knowledge of cardiovascular risk factors and of simple lifestyle modifications to reduce the cardiovascular risk burden. For each participant, family doctors, blinded to the information provided by patients, had to provide a global coronary risk based on the risk factors recorded in their electronic database, or report the missing information. RESULTS: The study sample comprised 560 subjects, 61% male, with mean age 60 +/- 9 years. Angina pectoris (49%) and myocardial infarction (40.9%) were the most frequently self-reported cardiovascular diseases in the study sample. The self-reported data revealed that 46% of the sample was overweight and an additional 20% overtly obese. Among those who self-reported arterial hypertension, approximately 11% admitted that they were unaware of their blood pressure, and 26% believed that they were normotensive but reported a recently detected blood pressure > 140/90 mmHg. Approximately 8% were not aware of whether they had high cholesterol levels, and among those who declared having normal cholesterol levels, 9% referred levels > 200 mg/dl. Of the sample, 22% self-reported diabetes, but 7% did not know whether they were diabetic or not. Thirty percent of the sample were smokers and among these, 40% smoked > 20 cigarettes/day. A low level of education was reported in 66% of the study sample. Women were more frequently obese, more often reported high cholesterol levels, had a low level of education and achieved a lower score from the questionnaire on knowledge of cardiovascular risk factors than men. Patients > 55 years more often reported an elevated blood pressure among those who defined themselves as normotensive, and achieved a lower score from the questionnaire on knowledge of cardiovascular risk factors than younger patients. CONCLUSIONS: With regard to secondary cardiovascular prevention, the study population was found to have insufficient knowledge of cardiovascular risk factors and of the correct approach to reduce their global risk despite the fact that the attitude of their family doctors in detecting and recording risk factors was above average.
