Could nasal septal deformities type 5 and 6 be a predictive factor of the indi- vidual genetic predilection for the onset of an acute coronary syndrome?.

OBJECTIVES: the possible impact of nasal septal deformities (SD) on cardiac pathology has not been well studied, despite growing evidence among data showing that upper air-way obstruction has a negative effect on cardiac function in general and a "deviated nasal septum" being considered one of the most frequent factors responsible for impaired nasal breathing. METHODS: a retrospective, case-control, double-blind study was performed on 249 patients who survived an acute coronary syndrome (ACS) attack. All patients underwent coronary angiography and were divided into coronary angiography positive (123 pts) and coronary angiography negative (126 pts) groups. The quality of nasal breathing was not considered in this study, but morphological aspects of the nasal septum (nasal septal deformities) were observed by anterior native rhinoscopy and endoscopic examination of the nose following the application of superficial anaesthesia. Mladina classification of nasal septal deformities was used. RESULTS: there was a statistically significant difference between coronary angiography negative and positive patients in Mladina type 1 to Mladina type 7 groups (p=0.000, X²=54.605). The incidence of nasal SD types 5 and 6 was higher in the group of ACS patients with the positive coronary angiography, whereas general distribution of the particular types of nasal septal deformities as they appear in the general population was found in the coronary angiography negative group. CONCLUSION: the fact that types 5 and 6 are inherited deformities and not related to trauma against the nose suggests the possible genetic predisposition for the onset of ACS with positive coronary angiography.

Prevalence of metabolic syndrome and related metabolic traits in an island population of the Adriatic.

BACKGROUND: Metabolic syndrome, a constellation of risk factors associated with cardiovascular disease and Type 2 diabetes, has reached epidemic proportions worldwide. Epidemiological studies in transitional societies will provide insight into the underlying factors that interact in its manifestation. AIMS: To estimate the prevalence of metabolic syndrome, provide a comparative analysis of two metabolic syndrome definitions and assess clustering and association of metabolic traits and cardiovascular diseases in an Adriatic island population. SUBJECTS AND METHODS: In a cross-sectional study, data on four anthropometric, blood pressure and 11 biochemical traits were obtained from 1430 adults from the island of Hvar. RESULTS: Prevalence of metabolic syndrome was 25% and 38.5% based on Adult Treatment Panel III and International Diabetes Federation definitions, respectively. Rates of abdominal obesity, elevated blood glucose and hypertension were high. Among the traits not included in the definitions, levels of LDL, total cholesterol and fibrinogen were markedly elevated. The majority of the phenotypes were significantly associated with the syndrome, the strongest being waist circumference. CONCLUSION: The Croatian islanders are characterized by a high prevalence of metabolic abnormalities. Central obesity is the strongest contributor of the syndrome. With a high prevalence of dyslipidemia and pro-inflammatory factors, the population is at substantial risk for cardiovascular diseases.
