Mitral valve is a complex cardiac structure composed of several components to work in synchrony to allow blood flow into left ventricle during diastole and not to allow blood flow into left atrium during systole. Accessory mitral valve tissue (AMVT) was defined as existence of any additional part and parcel of valvular structure which has an attachment to normal mitral valve apparatus in left-sided cardiac chambers. AMVT may present itself in different clinical circumstances ranging from a silent clinical course to thromboembolic events, heart failure, left ventricular outflow tract obstruction, and severe arrhythmia. This article reviews the clinical perspectives of AMVT in terms of symptoms, diagnosis, and treatment, providing a new anatomical classification regarding the location of AMVT. Briefly type I refers to AMVT having attachments on the supra leaflets level, type II refers to attachments on the mitral leaflets, and type III refers to attachment below the mitral leaflets. Increased awareness and widespread use of echocardiographic techniques would increase recognition of AMVT in patients with heart murmurs but otherwise healthy and in those with left ventricular outflow tract obstruction or tissue which causes subaortic stenosis and with unexplained cerebrovascular events.
Venous diseases encompass a large spectrum of abnormalities in the venous system with complaints, such as aching and swelling. Enhanced external counterpulsa-tion, proven safe and effective in ...patients with coronary artery disease and chronic heart failure, is a technique that increases venous return and augments diastolic blood pres-sure. This study assessed the effects of enhanced external counterpulsation on symp-toms of venous disease using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms questionnaire.
This study was designed prospectively for evaluating venous symptoms before and after enhanced external counterpulsation treatment. The study population con-sisted of 30 consecutive patients who were admitted to the cardiology clinic. The Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms ques-tionnaire was applied to assess venous symptoms one day before and after enhanced external counterpulsation treatment.
The mean age of the patients was 64.62 ± 9.67 years. After 35 hours of enhanced external counterpulsation, 28 patients (93%) had at least 1 New York Heart Association functional class reduction compared with baseline and 43% of patients had 2 New York Heart Association functional classes improvement. The New York Heart Association class significantly decreased after enhanced external counterpulsation treatment (P<.001). There was a significant improvement in their swelling and night cramps symptoms compared with baseline (P< .001 and P = .05, respectively). Also, The left ventricular ejec-tion fraction significantly increased after the enhanced external counterpulsation treat- ment (P = .02).
The findings obtained in the present study suggested that patients treated with enhanced external counterpulsation showed a significant reduction in swelling and night cramps symptoms. Although the total VEIN score did not change after the enhanced external counterpulsation procedure, improvement in swelling and night cramps under-lines the beneficial effects of enhanced external counterpulsation through the venousvascular territory.
Lower extremity venous diseases or insufficiency include clinically deteriorating conditions with morphological and functional alterations of the venous system, including venous hypertension, ...vascular wall structural abnormality, and venous valvar incompetency in association with an inflammatory process. In fact, the same pathophysiological processes are the main underlying mechanisms of other venous insufficiencies in different vascular territories such as Peripheral Varicose Vein (PVV), varicocele, Pelvic Varicosities or Congestion Syndrome (PCS) and Hemorrhoidal Disease (HD). Regarding the anatomical continuity of lower extremity venous system, urogenital system (pampiniform plexus in male and broad ligament and ovarian veins in female) and anorectal venous system, it is reasonable to expect common symptoms such as pain, burning sensation, pruritis, swelling, which arise directly from the involved tissue itself. High coexistence rate of PVV, varicocele/PCS and HD between each other underlines not only the same vascular wall abnormality as an underlying etiology but also the existence of common symptoms originating from the involved tissue in dilating venous disease. Accordingly, it might be reasonable to query the common symptoms of venous dilating disease in other venous vascular regions in patients with complaints of any particular venous territory.
OBJECTIVESTo determine the effects of nebivolol on oxidative stress, insulin resistance, adiponectin and plasma soluble P-selectin levels in hypertensive patients in comparison with metoprolol.
...MATERIAL AND METHODSEighty newly diagnosed hypertensive patients in grade 1 hypertension according to the European Society of Hypertension and European Society of Cardiology guidelines were enrolled in this prospective, blinded, randomized study. Seventy-two patients completed the study. After baseline assessment, each patient was randomly allocated to a 5 mg daily dose of nebivolol (n = 37, 20 male) or a 100 mg daily dose of metoprolol (n = 35, 18 male) and treated for 6 months. Blood pressure, heart rate, oxidative stress (malonyldialdehyde), homeostasis model assessmentinsulin resistance, adiponectin and plasma soluble P-selectin levels were measured before and after treatment.
RESULTSAt the end of treatment, nebivolol and metoprolol significantly decreased blood pressure and heart rate, with a more pronounced bradycardic effect of metoprolol. Nebivolol, but not metoprolol, significantly lowered oxidative stress (P = 0.03), the insulin resistance index (P = 0.003) and plasma soluble P-selectin levels (P = 0.008), and increased adiponectin levels (P = 0.04).
CONCLUSIONNebivolol, in contrast to metoprolol, improved oxidative stress, insulin sensitivity, decreased plasma soluble P-selectin and increased adiponectin levels in hypertensive patients. These beneficial effects of nebivolol may contribute to a reduction in cardiovascular risk in hypertensive patients.
Asthma is a chronic airway disease in which the pathological mechanisms are reversible airway obstruction, bronchial hyper reactivity, and constriction of the lower airways. Supraventricular ...tachycardia (SVT) is a common arrhythmia which originates above the bundle of His and causing heart rates exceeding 150 beats/min. SVT patients present with palpitation, chest pain, chest discomfort, dyspnea, hyperventilation, and lightheadedness, occasionally. Besides, extraordinary presentations of SVT are available in literature. In this report, we describe a case of a patient presenting with treatment-resistant asthma-like attacks lasting for 20 years whom was suspected SVT as an underlying etiology and treated by slow pathway radiofrequency ablation.
Abstract Background The underlying mechanism by which osteoporosis and cardiovascular disease may be linked is not fully understood. However studies mainly focused on the association between bone ...mineral density (BMD) and cardiovascular risk factors or atherosclerosis itself by only assessing the presence of vascular calcification. In this study we aimed to evaluate both cardiovascular risk factors, and presence of coronary artery disease (CAD) in post-menopausal women patients with and without low BMD. Materials and methods Study population consisted of post menopausal women who were scheduled to coronary angiography. Two hundred and twenty seven consecutive female patients were included in the study and evaluated for the presence of cardiovascular risk factors and CAD. Bone mineral density was measured in all patients either the day before or the day after coronary angiography. Low BMD was defined as T score < − 1 and normal BMD was defined as T score ≥ − 1. For statistical analysis patients were divided into two groups: patients with low BMD and patients with normal BMD. Results There were not statistically significant differences between two groups in respect to body mass index, presence of diabetes mellitus, hypercholesterolemia, and smoking status. Age and presence of CAD was found to be statistically different between two groups being higher in patients with low BMD. Logistic regression analysis revealed that age was positively and independently associated with low BMD in post menopausal female patients (Odds ratio = 1.072 CI: 1.036–1.11, p = 0.001). Conclusion Age is found to be an independent predictor of decreased BMD in our study population recruited from the coronary angiography laboratory. However, neither cardiovascular risk factors, nor coronary artery disease itself has been found to be associated with low BMD.
