    ABSTRACT: Combination therapy is needed to achieve adequate control of blood pressure in most patients, especially those with systolic blood pressure ≥160 mmHg or diastolic ≥100 mmHg. Hypertension guidelines recommend the combination of at least two drugs with complementary mechanisms of action to achieve blood pressure control. In combination therapy, there are physiological and pharmacological synergies between different classes of agents, which cause a greater blood pressure reduction and fewer side-effects. Renin-angiotensin-aldosterone system blockade is a cornerstone of antihypertensive therapy. Many studies showed the effectivenes of angiotensin receptor blocker (ARB) in patients with hypertension, and they are among those most widely used in antihypertensive therapy. The combination of ARBs with either a diuretic or a calcium antagonist are among the preferred combinations. These combinations are well tolerated, effective, and causes blood pressure reductions and control rates than those that can be achieved with monotherapy. Olmesartan is an angiotensin II receptor antagonist which is widely examined in combination of either hydrochlorothiazide or amlodipine, showing improvements in antihypertensive efficacy with good tolerability. The aim of this review was to evaluate the combination of ARBs with diuretic and calcium channel blockers.

    ABSTRACT: It was estimated that, total number of adults with hypertension was approximately 1 billion worldwide. This number was predicted to increase to a total of 1.5 billion in 2025. Hypertension is the most important risk factor for cardiovascular morbidity and mortality. The relationship between blood pressure and risk of cardiovascular events is continuous, consistent, and independent of other risk factors. The higher the blood pressure, the greater the possibility of heart attack, heart failure, stroke, and kidney diseases. The main purpose of hypertension treatment is to reduce the cardiovascular and renal morbidity and mortality. In this review, the principles of pharmalogical therapy and evolving role of angiotension receptor blockers in hypertension will be summarised according to recent guidelines.

    ABSTRACT: Hypertensive emergency usually appears in older patients with previous recurrent episodes, and is among the most frequent admissions to emergency departments. A 29-year-old woman was referred to our clinic with the diagnosis of hypertensive emergency. The patient complained of severe headache, dyspnea, palpitation, diaphoresis, and confusion due to hypertensive encephalopathy. Her blood pressure was 250/150 mmHg on admission. At the referral hospital, the patient had undergone cranial CT because of her confused state and this excluded acute cerebral hemorrhage. Also at that hospital, thoracoabdominal CT for differential diagnosis depicted an adrenal mass with a necrotic core. After admission to our clinic, initial control of excessive blood pressure was not achieved despite high dose intravenous nitrate therapy. Thereafter intravenous esmolol treatment was initiated simultaneously with oral alpha blocker therapy in order to counterbalance the unopposed alpha adrenergic activity with beta blocker therapy. After 12 hours, sudden onset of hypotension developed and deepened despite IV saline, inotropic and vasopressor agents such as IV dopamine, noradrenaline and adrenaline. The patient died at the 24th hour due to hemodynamic collapse as a result of hyperadrenergic state due to possible pheochromocytoma crisis. This case is an exceptional example of hypertensive emergency secondary to fulminant pheochromocytoma crisis failing to respond to intensive antihypertensive treatment, and in which patient death was unavoidable due to uncontrolled excessive adrenergic activity which led to profound cardiogenic shock.

    ABSTRACT: Objective: The objective of this study was to retrospectively analyze the clinical course and postoperative long-term survival of patients diagnosed with isolated left main coronary artery (LMCA) stenosis after surgical revascularization. Methods: A total of 38 patients (27 males, 11 females) who were diagnosed with isolated LMCA stenosis and underwent surgical revascularization were enrolled in the study. Isolated LMCA stenosis was classified into 2 groups: ostial stenosis and nonostial stenosis. Coronary events were defined as death of cardiac origin, the need for a new myocardial revascularization procedure, or the occurrence of myocardial infarction in the course of follow-up. The postoperative assessment period included short- and long-term follow-up. The study endpoint was defined as all-cause mortality. Results: Among the 38 patients who participated in the study, 25 suffered from ostial LMCA stenosis. The early postoperative mortality rate before hospital discharge was 2.6%. Median duration of postoperative long-term follow-up was 73.43 months (range: 0.17-187.23). Median duration of long-term follow-up free from coronary events or percutaneous coronary interventions was 73.43 months. Postoperative 2-year survival rate was 97.4%, and 5-year survival rate was 92.1%. The postoperative survival period and period free of coronary events of patients with isolated ostial LMCA stenosis did not differ significantly from those of patients with nonostial stenosis (p=0.801, p=0.970, respectively). Conclusion: Postoperative short- and long-term prognosis of isolated LMCA stenosis appears good in terms of mortality and coronary event symptoms.

    ABSTRACT: Objective: Hypothyroidism is associated with increased cardiovascular morbidity and mortality. Subclinical hypothyroidism is one of the most common endocrine diseases among the general population. The aim of the present study was to investigate aortic elastic parameters related to increased cardiovascular risk in patients with subclinical hypothyroidism. Methods: Fifty patients newly diagnosed with subclinical hypothyroidism and 50 healthy, age- and sex-matched euthyroid controls were included. Following physical examination and routine biochemical analysis, systolic and diastolic diameters of the ascending aorta were measured by transthoracic echocardiography, and aortic elasticity parameters were calculated. Results: Age, gender, and body mass index were similar between the groups. Patients had significantly higher C-reactive protein and thyroid-stimulating hormone levels than the control group (p=0.002 and p<0.001, respectively). Aortic stiffness was significantly higher in patients, but aortic strain values were significantly lower (p<0.001). Aortic stiffness, C-reactive protein, aortic strain, and systolic blood pressure were found to be independent predictors of subclinical hypothyroidism in multivariate logistic regression analysis (p<0.05). Conclusion: Subclinical hypothyroidism is associated with impairment of aortic elastic parameters, independent of other cardiovascular risk factors.

    ABSTRACT: Objective: Epicardial fat thickness (EFth) is associated with both left ventricular hypertrophy (LVH) and diastolic dysfunction. However, the effect of EFth on myocardial performance is not known. The aim of this study was to investigate the relationship between EFth and tissue Doppler myocardial performance index (TD-MPI), which incorporates both systolic and diastolic left ventricular (LV) function, in newly diagnosed hypertension (HT) patients. Methods: A total of 314 consecutive, newly diagnosed HT patients were prospectively included (mean age: 51.9±1.7 years). EFth was measured perpendicularly on the free wall of the right ventricle at the end of the systole in 2 echocardiographic views (parasternal short and long axis). Myocardial performance index (MPI) was calculated using tissue Doppler (TD) echocardiography. Patients were divided into 2 groups according to median TD-MPI levels (TD-MPIlow and TD-MPIhigh). Results: EFth values of the TD-MPIhigh group were higher than those of the TD-MPIlow group (p<0.05). Patients in the TD-MPIhigh group also had higher age, body mass index, systolic blood pressure (SBP), diastolic blood pressure (DBP), left ventricular mass index (LVMI), E/A ratio, and aortic distensibility, compared with the TD-MPIlow group (p<0.05 for all). Multivariate linear regression analysis showed that TD-MPI was independently associated with age (ß=0.089, p=0.012), LVMI (ß=0.090, p=0.05), E/A (ß=-0.118, p=0.005), and EFth (ß=0.432, p<0.001). Conclusion: TD-MPI was independently associated with EFth in patients with newly diagnosed HT. EFth may be used as a predictor of impaired LV global functions in patients with normal left ventricular ejection fraction (LVEF) and newly diagnosed HT.

    ABSTRACT: Based on the definition in the European Society of Cardiology statement, myocarditis is an inflammatory disease of the myocardium diagnosed by established histological, immunological, and immunohistochemical criteria, whereas inflammatory cardiomyopathy is myocarditis in association with cardiac dysfunction. Actual incidences of myocarditis and CMi are difficult to determine. Studies addressing the issue of sudden cardiac death in young people report a highly variable autopsy prevalence of myocarditis, ranging from 2-42% of cases. Similarly, biopsy-proven myocarditis has been reported in 9-16% of adult patients with unexplained nonischemic dilated cardiomyopathy (DCM). In up to 30% of cases, biopsy-proven myocarditis can progress to DCM and is associated with a poor prognosis. Prognosis in myocarditis patients also varies according to underlying etiology.

    ABSTRACT: Arteriovenous fistulas (AVFs) are unusual connections between the arterial and venous system that bypass the normal anatomic capillary beds. This case report presents an arteriovenous fistula of the lower extremity caused by a penetrating injury. The patient was diagnosed by Duplex ultrasonography. Diagnostic catheterization of the affected limb showed a high-flow AVF between the left profunda femoris artery and left femoral vein with a deep femoral vein aneurysm measuring 9x4 cm. The AVF was successfully treated with coil embolization.

    ABSTRACT: Non-compaction cardiomyopathy (NCM) is a rare congenital cardiomyopathy characterized by deep increased trabeculation in one or more segments of the ventricle. The apical segment of the left ventricle is most commonly affected, but left ventricular basal segment, biventricular involvement or right ventricle predominance have also been described. While some neuromuscular anomalies and myopathies had been described in systemic sclerosis patients, coexistence of chronic inflammatory disorders and NCM is unclear. This paper presents a case of biventricular NCM with severe systolic and diastolic dysfunction in a 40-year-old female diffuse cutaneous systemic sclerosis patient.

    ABSTRACT: Objective: Cardiac manifestations of neurofibromatosis type 1 (NF1) may include hypertension, congenital heart disease, and hypertrophic cardiomyopathy. The aim of this study was to evaluate cardiac abnormalities in patients with NF1. Methods: Sixty-five NF1 patients (mean age: 9±4.48 years) were retrospectively studied. Standard electrocardiography and echocardiography were performed in all patients. Results: Cardiac abnormalities were found in 11 of the 65 patients (15.3%). Five patients had mitral valve regurgitation, 2 patients had secundum atrial septal defect, 1 patient had pulmonary valvular stenosis, 1 patient had ventricular septal defect, 1 patient had tricuspid valve regurgitation, and 1 patient had aortic valve regurgitation. Conclusion: Cardiac abnormalities have potential long-term hemodynamic consequences that justify an early diagnosis. Thus, for any patient with NF1, a cardiologic assessment is mandatory at the time of diagnosis and with regular follow-up intervals.
