ABSTRACT
<p><b>INTRODUCTION</b>Atherosclerotic cardiovascular disease is a global health burden. However, there are heterogeneities among countries or regions in the risk factors and clinical manifestations of atherosclerotic diseases as well as management patterns.</p><p><b>METHODS</b>We collected data from 25 centres in Thailand. Patients with documented coronary artery disease, cerebrovascular disease or peripheral arterial disease, or with at least three atherosclerosis risk factors were enrolled between April 2011 and March 2014. Data on demographics, atherosclerosis risk factors and the management pattern of risk factors, including laboratory findings, were recorded.</p><p><b>RESULTS</b>In total, 9,390 patients, including 4,861 patients with established atherosclerotic disease and 4,529 patients with multiple risk factors, were enrolled. The modifiable risk factors, other than current smoking habit (5.3%), were common: hypertension (83.8%), dyslipidaemia (85.9%) and diabetes mellitus (57.4%). A majority of patients with hypertension (96.3%), dyslipidaemia (93.8%) and diabetes mellitus (78.5%) received medications for their conditions. Antiplatelet agents were given to 73.9% of patients. The undertreatment rate of cardiovascular risk factors, such as blood pressure, low-density lipoprotein cholesterol, haemoglobin A1c and smoking status, was 35.8%, 59.0%, 45.3% and 5.3%, respectively.</p><p><b>CONCLUSION</b>Conventional atherosclerosis risk factors were common among Thai patients with established atherosclerotic disease. Even though most of the patients received recommended treatments according to established guidelines, a significant proportion of them were undertreated for atherosclerosis risk factors.</p>
ABSTRACT
Background It is well-established that influenza vaccination reduces adverse cardiovascular outcomes in patients with cardiovascular diseases (CVD), however, the vaccine coverage rate in most countries remains low. The concern about the local adverse effects of intramus-cular injection, particularly in CVD patients receiving antithrombotic therapy, is one of the important impediments. This study was con-ducted to assess the safety, side effects and tolerability of intradermal influenza vaccine in CVD patients. Methods This was an observa-tional study in adult CVD patients who had undergone vaccination against seasonal influenza by intradermal vaccination between May 16th and May 30th, 2012 at Maharaj Nakorn Chiang Mai Hospital. The medical history, patients’ acceptability and adverse effects were collected using a written questionnaire completed by the patient immediately following vaccination and by a telephone survey eight days later. Results Among 169 patients, 52.1%were women and the mean age was 63 ± 12 years. Coronary artery disease, valvular heart disease and dilated cardiomyopathy were present in 121 (71.6%), 40 (23.7%) and 8 (4.7%), respectively. Antithrombotics were used in 89.3%. After vaccination, the pain score was 0, 1 or 2 (out of 10) in 44.4%, 15.1%, and 27.6%of the patients, respectively. Eight days after vaccination, the common adverse reactions were itching 19 (11.9%), swelling 9 (5.7%) and fatigue (4.7%). No hematoma or bruising was reported. Conclusions The intradermal influenza vaccination is safe and well tolerates with high rates of satisfaction in CVD patients. This technique should be useful in expanding influenza vaccine coverage.
