Background: Hypertrophic cardiomyopathy (HCM) is a genetic disease associated with risk of morbidity and sudden cardiac death. The prevalence, hypertrophy patterns, mode of presentations, and different ECG findings vary in different regions of the world. To date, no data is present regarding these variables in Qatar. Patients and Methods: A retrospective, cross sectional, descriptive analysis of all patients referred for echocardiography study at Hamad General Hospital, Qatar. The study period was from January 2008 till December 2010. Aims: To study 1) the prevalence of HCM, 2) the different patterns of hypertrophy, and 3) the clinical and ECG presentations in this population. Results: Out of the 29,286 cases evaluated, 38 patients were found to have HCM (0.13%). Their clinical, ECG, and echocardiography findings were analyzed. Mean age was 47 y, 35 males (92%) and 3 females (8%). Four patterns of hypertrophy were described; 17 (44.7%) had septal hypertrophy alone, 6 (15.8%) had septal and other segments hypertrophy but sparing the apex, 10 (26.3%) had apical segments along with any other segment hypertrophy, and 5 (13.2%) had apical hypertrophy alone. No obstruction was found in 19 (50%), left ventricular outflow (LVO) tract obstruction was found in 13 (34%), and mid cavity obstruction (MCO) in 6 (16%). Twenty one (55.3%) patients were referred because of chest pain, 15 (39.5%) with palpitations, 15 (39.5%) with shortness of breath, and 5 (13.2%) with syncope. Nine patients (23.7%) were asymptomatic and were referred because of cardiac murmur during routine examination. ECG evidence of LV hypertrophy was found in 29 (76.3%). Conclusion: The prevalence of HCM in our population group is 0.13% with a male predominance (12:1). There was a diversity of clinical presentation, ECG abnormalities and patterns of LV hypertrophy among HCM patients.

Background: Ultrasound detected intima-media thickness (IMT) of the carotid artery and thoracic aorta are possible screening tests to assess the risk of coronary artery disease (CAD) in asymptomatic individuals. Objective: Aim of the study was to assess the utility of carotid and aortic IMT as a predictor of CAD and to assess the extent of IMT with severity of CAD in a South Indian population. Patients and Methods: A cross-sectional and analytical study was carried out among 40 cases, who had angiographic evidence of CAD against 30 healthy control subjects with a normal treadmill test. At plaque-free regions, the carotid IMT was evaluated by B-mode ultrasonography and thoracic aorta IMT was evaluated by trans-esophageal echocardiography (TEE). The significance of difference in means between two groups was analyzed using one-way ANOVA F-test and the significance of difference in proportions by Chi-square test. Multiple comparisons were done by Bonferroni t test. The correlation between IMT and severity of CAD was assessed by Spearman's method. Results: There were 38 males and 2 females among cases with age 51.7 ± 8.3 years, and 28 males and 2 females among control subjects with age 52.2 ± 7.1 years. Increased carotid IMT was noted among 24 cases and 2 control subjects, and the association was significant for CAD [P < 0.001, Chi-square = 20.89, odds ratio (OR) = 21.00, and 95% confidence interval (CI) = 4.78-89.59]. Similarly, 19 cases and one control subject had abnormal IMT with positive correlation for CAD (P < 0.001, Chi-square = 16.39, OR = 28.24, and 95% CI = 4.06-163.21). There was no association between IMT and diabetes, hypertension, or smoking; however, IMT was significantly associated with age and dyslipidemia. Also, there was no correlation between extent of IMT and severity of CAD. Conclusions: IMT of the carotid and thoracic aorta is strongly associated with risk of CAD in a South Indian population, and may be used as a non-invasive screening tool for coronary atherosclerosis in resource-limited settings. The presence of dyslipidemia influenced IMT and may be used as a tool to follow patients on hypolipidemic drugs.

Aim of the study: To study the IMT of the common carotid arteries and correlate with documented coronary artery disease. Patients and Methods: The study was conducted in subjects with history of coronary artery disease in the past and who presented with acute coronary syndrome. After detailed history and examination, investigations were carried out as per our protocol. The sample size was 100, with 70 in the case group and 30 in the control group (matched).B-mode ultrasonography scanning of the carotid arteries was performed and measurements were made at proximal, middle and distal segments of the common carotid arteries. Univariate analysis was used to confirm the significance of the variables and multiple regressions were used to predict the risk, based on significant variables. Results: The total study sample consisted of 100 subjects, of whom 70 were cases and 30 were controls. The case group comprised of a total of 70 patients with a mean age of 58.72 years. In the control group of 30 patients, the mean age was 62.73 years. In the study group, 77.1% (n=54) were males and 22.9% (n=16) were females. In the study group, 51.4% (n=36) were smokers compared with 13.3% (n=4) among the control group (P=0.001 vhs). In the study group, 20% (n=14) had diabetes while this was 13.3% (n=4) among the control group. In the study group, 52.96% (n=37) had hypertension while 16.7% (n=5) had hypertension in the control group (P=0.001 vhs). The mean total cholesterol among the study group was 197.4mg/dl while in the control group it was 175.9 mg/dl. Thirty-two percent of the patients with CAD had anterior lateral wall ischemia, 21% had anterior wall, 21% lateral wall, 19% inferior wall and 7% unstable angina. The mean carotid IMT in the study group was 0.923 ± 0.123 and in control group it was 0.689 ± 0.051 (P=0.001). The mean carotid intima thickness was significantly high in the case group as compared with the control, and the P-value was highly significant. Conclusion: The carotid IMT was found to be higher in patients with coronary artery disease, and there was a statistically significant difference between cases and controls. Thus, our study shows that carotid IMT is a marker of atherosclerosis that is strongly associated with risk factors and can be used as a surrogate marker in the prediction of atherosclerosis in coronary artery disease. As it is easily reproducible, carotid B-mode ultrasonography is a safe, non-invasive and reproducible procedure that helps in the early identification of clinical coronary artery disease.

Introduction: As chest pain is an important symptom of coronary artery disease (CAD), the presentation of the symptom often prompts referral to a cardiologist for further investigation. The aim of the present study is to determine the prevalence of anxiety and depressive symptoms in patients referred to a cardiology outpatient clinic for performing the stress test. Patients and Methods: Two hundred and fifty consecutive outpatients referred for evaluation of chest pain by the stress test at a government cardiology clinic from April 2010 to November 2010 were asked to participate in the study. We estimated the prevalence of anxiety and depression symptoms, as assessed by the Hospital Anxiety and Depression Scale, in a sample of patients with chest pain. Results: The prevalence of anxiety and depressive symptoms was estimated to be 42% and 31%, respectively, in the total chest pain population. Males with abnormal test were depressed but females experienced more anxiety symptoms. Patients with negative tests had significantly higher scores for anxiety and higher depression scores than those with positive tests. Eleven percent of the patients with positive tests were women and 23% were men. Conclusion: Determining a patient's anxiety disorder history may assist the clinician in identifying, especially, women with angina who are at a lower risk of underlying CAD.

Ciguatera fish poisoning occurs with ingestion of fish containing ciguatoxin. It causes a clinical syndrome that comprises classic gastrointestinal, neurological and cardiovascular symptoms. Ciguatoxin is a sodium channel agonist with cholinergic and adrenergic activity. Although cardiovascular symptoms are rare with ciguatoxin, we report two cases with bradycardia and hypotension. Fatality and long-term sequelae are not uncommon with ciguatoxin poisoning and educating the general population is essential.

Dipping smokeless tobacco (ST) is used worldwide. We report a case of acute myocardial infarction in a young patient, who consumed smokeless tobacco (Sweka) for over one year. ST may be as harmful as smoking and carries adverse cardiac complications. A prompt call for restriction and prohibition is advised and its alternative use to quit smoking must be abandoned.

We report a 61-year-old male patient who presented with one month history of exertional dyspnea, persistent dry cough, abdominal pain with distension, poor appetite, and weight loss. This case illustrates a rare presentation of hepatocellular carcinoma with mobile right atrial thrombus and pulmonary embolism along with disseminated tumor thrombosis at multiple sites. Furthermore, this case reiterates that an early detection and diagnosis may have increasing importance in the advent of new therapies for treating advanced hepatocellular carcinoma
