AB0812 IS THE VISCERAL ADIPOSITY INDEX ASSOCIATED WITH THE PRESENCE OF CARDIOVASCULAR RISK SCORES AND COMORBIDITY IN PSORIATIC DISEASE?

Background:

Psoriatic disease (PsD) is a chronic immune-mediated inflammatory disorder and predominantly involves the skin and joints. There is a better known relationship between the severity of PsD with some comorbidities such as metabolic syndrome, cardiovascular disease and obesity. Visceral Adiposity Index (VAI) has been shown to be an important marker, gender- dependent for insulin resistance, adipose tissue function and distribution.

Objectives:

The aim of this study was to evaluate the relationship between the VAI and cardiovascular risk scores of patients with psoriatic arthritis.

Methods:

This study was conducted with 101 PsD patients who fulfilled the classification criteria for Psoriatic Arthritis (CASPAR) criteria and 98 healthy subjects. Demographic and clinical data were recorded. Disease activity was evaluated with the Health Assessment Questionnaire (HAQ), Disease Activity Index for Psoriatic Arthritis (DAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Disease Activity Index (BASFI) and Psoriasis Area Severity Index (PASI). The SCORE, Framingham index, metabolic syndrome (MetS), Body mass index (BMI) and VAI values of the patients and the VAI values of the healthy subjects were calculated.

Results:

Mean BMI (kg/m2) was calculated as 29.63 5.66. According to the SCORE measurements, 53 (52.5%) patients were at low risk, 45 (44.6 %) at moderate risk, and 3 (3 %) at high risk. No patients were at very high risk. According to the Framingham score, 72 patients (71.3%) were at low risk, 22 patients (21.8%) at intermediate risk and 7 patients (6.9%) at high risk. The risk was found to be statistically significantly higher in the PsD group compared to the healthy control group in respect of metabolic syndrome, obesity (BMI >30) and VAI levels (p<0.05). Significantly higher VAI levels were determined in PsD patients with metabolic syndrome, BMI> 30 (obesity), diabetes mellitus and hypertension compared to without these comorbidities (p<0.05). A statistically significant correlation was determined between low and moderate risk Framingham score, and the VAI levels of PsD patients. Correlations were determined between disease activity and metabolic and cardiovascular risks of patients. A weak correlation was observed between VAI levels and the Framingham score (Table).

Conclusion:

Patients with psoriasis are more susceptible to obesity and other diseases such as metabolic syndrome, dyslipidemia, cardiovascular diseases, insulin resistance and diabetes. Therefore, control of bodyweight in PsD patients is important for management of the disease. Since VAI can be calculated simply from routinely taken measurements, the VAI level can be used to determine cardiovascular risk and VAI may also provide clues about comorbidities in patients with newly diagnosed PsD.

Early Results of Valved Bovine Jugular Vein Conduit for Right Ventricular Outflow Tract Reconstruction

Objective

Many congenital cardiac anomalies present with accompanying severe right ventricular outflow tract (RVOT) obstruction or interruption requiring surgical correction. RVOT reconstruction by means of a conduit is often necessary in the majority of these patients in the early years of life and there are several proposed conduits for this purpose.

Methods

Fourteen patients with different congenital cardiac pathologies underwent RVOT reconstruction with the newly developed bovine valved jugular vein conduit (The Contegra conduit). The function of the conduit is observed by echocardiographic examinations at the hospital discharge and at follow-up visits with special attention to the function of the venous valve and to any gradient on the RVOT.

Results

There were two perioperative mortalities. All the surviving patients are followed for a mean period of 8.07 months (range 2 to 33 months). The function of the venous valve was determined, in 4 patients (33.33%) as without regurgitation, in 7 patients (58.3%) as mild regurgitation and in 1 patient (8.33%) as mild-to-moderate regurgitation. The reconstructed RVOT was free of any significant gradient at the hospital discharge (mean 10.83 ±10.18 mmHg) and at the follow-ups (mean 12.916 ±12.33 mmHg). There was not a trend towards an increase in the gradients following discharge.

Conclusion

The early results of the Contegra valved conduit are very satisfactory. This graft can be a good alternative for RVOT reconstruction, particularly in the neonatal and infant patient group. These patients can be managed by homograft replacement of their conduit in later years.

Evaluation of prehypertension and masked hypertension rate among clinically normotensive patients

BACKGROUND

The present cross-sectional study was aimed to identify pre-hypertension and masked hypertension rate in clinically normotensive adults in relation to socio-demographic, clinical and laboratory parameters.

METHODS

A total of 161 clinically normotensive adults with office blood pressure (OBP) <140/90 mmHg without medication were included in this single-center cross-sectional study. OBP, home BP (HBP) recordings and ambulatory BP monitoring (ABPM) were used to identify rates of true normotensives, true pre-hypertensives and masked hypertensives. Data on sociodemographic and clinical characteristics were collected in each subject and evaluated with respect to true normotensive vs. pre-hypertensive patients with masked hypertension or true pre-hypertensive. Target organ damage (TOD) was evaluated in masked hypertensives based on laboratory investigation.

RESULTS

Masked hypertension was identified in 8.7% of clinically normotensives. Alcohol consumption was significantly more common in masked hypertension than in true pre-hypertension (28.6 vs. 0.0%, p = 0.020) with risk ratio of 2.7 (95% CI 1.7-4.4). Patients with true pre-hypertension and masked hypertension had significantly higher values for body mass index, waist circumference, systolic and diastolic OBP and HBP (p < 0.05 for each) compared to true normotensive subjects. ABPM revealed significantly higher values for day-time and night-time systolic and diastolic BP (p = 0.002 for night-time diastolic BP, p < 0.001 for others) in masked hypertension than true pre-hypertension.

CONCLUSIONS

Given that the associations of pre-hypertension with TOD might be attributable to the high prevalence of insidious presentation of masked hypertension among pre-hypertensive individuals, ABPM seems helpful in early identification and management of masked hypertension in the pre-hypertensive population.

Right ventricular outflow tract reconstruction for tetralogy of fallot with abnormal coronary artery: experience with 35 patients

BACKGROUND

An abnormal coronary artery crossing the right ventricle outflow tract (RVOT) complicates complete repair of tetralogy of Fallot (TOF). We have evaluated surgical options for RVOT reconstruction for this group of patients.

METHODS

Between 1984 and 2002, 35 TOF patients with abnormality of coronary arteries underwent total correction. Age of these patients ranged from 1 to 14 years (mean 5.8 +/- 2.8 years). All patients were diagnosed by echocardiography and 25 patients had cardiac catheterization. All the abnormal coronary arteries were spared at the operation. In 24 patients a transannular patch was applied for RVOT reconstruction. In three patients with an adequate pulmonary annulus, oblique ventriculotomy incisions, and in two patients, transatrial approaches were performed. "Two-patch" technique was chosen for two patients. In four patients placement of an extracardiac conduit was necessary.

RESULTS

Mortality was observed in four patients, in two of them due to suspected myocardial ischemia. None of the surviving patients needed reoperation. All of them were in NYHA class I. The follow-up period for patients without extracardiac conduit was between 14 and 96 months (mean 50.2 months) and for the patients with extracardiac conduit ranged 36 to 98 months (63.5 months). The mean gradients measured by echocardiography were, respectively, 5 mmHg (range 0 to 35 mmHg) and 23.75 mmHg (range 20 to 25 mmHg).

CONCLUSIONS

Definitive repair of TOF patients with abnormal coronary arteries can be performed in early childhood, but care should be taken to leave at least 1 cm of myocardium between the sutureline and the abnormal coronary artery. Detailed evaluation of the patients preoperatively is mandatory to identify the strategy and timing of the operation.

Radiation-induced coronary artery disease

Radiation-induced heart disease must be considered in any patient with cardiac symptomatology who had prior mediastinal irradiation. Radiation can affect all the structures in the heart, including the pericardium, the myocardium, the valves and the conduction system. In addition to these pathologies, coronary artery disease following mediastinal radiotherapy is the most actual cardiac pathology as it may cause cardiac emergencies requiring interventional cardiological or surgical interventions. Case A 36-year-old man was admitted to the clinic with unstable angina pectoris of one month duration. The patient had no coronary artery disease risk factor. The history of the patient revealed that he had mediastinal radiotherapy due to Hodgkin's disease at 10-year of age. Coronary arteriography showed total occlusion of the left anterior descending artery and 70% stenosis of the proximal right coronary artery. Both arteries are dilated with placement of two stents. Control coronary arteriography at the end of the first year showed patency of both stents and the patient is free of symptoms. Previous radiotherapy to the mediastinum should be considered as a risk factor for the development of premature coronary artery disease. Percutaneous transluminal coronary angioplasty with stent placement or surgical revascularization are the preferred methods of treatment. Preoperative assessment of internal thoracic arteries should be considered prior to surgery. As the radiation therapy is currently the standard treatment for a number of mediastinal malignancies, routine screening of these patients and optimal cardiac prevention during radiotherapy are the only ways to minimize the incidence of radiation-induced heart disease.

Accessory mitral valve tissue causing severe subaortic stenosis with dextrocardia in a premature newborn

We report an unusual case of left-ventricular outflow obstruction caused by accessory mitral valve tissue associated with dextrocardia and ventricular septal defect in a seven-day-old, 2200 grams premature infant, who was referred with a heart murmur. The diagnosis was made by two-dimensional and Doppler echocardiography which demonstrated the accessory tissue as well as a 100 mmHg peak systolic gradient between the left ventricle and the aorta. Ten days after the presentation the infant underwent emergency surgery after respiratory arrest and recurrent episodes of syncope. The accessory mitral valve tissue and its fibrous extension were excised and the ventricular septal defect was closed. We believe that surgical treatment of patients with accessory mitral valve tissue should be performed early because of the possibility of acute deterioration. Combined aortotomy and interatrial approach is very helpful in evaluating the anatomy and the mitral valve function as well as delineating the tissue to be excised.
