Background. Obesity and overweight are two pathologies that are more and more frequent in the XXIst century diagnosis and are causing high morbidity and mortality rates in the general population, especially through cardiovascular complications.

Aims. Identification and early diagnosis of cardiac changes in overweight and obese patients. Material and method. We carried out a sectional, analytical and observational study on 111 subjects: 27 normal weight subjects and 84 overweight and obese patients, which were submitted to a clinical exam, biochemical exams and 2D ultrasound.

Results. The presence of diastolic dysfunction is twice more frequent in overweight patients in comparison to normal weight ones (30% vs 15%) and 5 times more frequent in obese patients than normal weight ones (75% vs 15%). The size increase of the interventricular septum is correlated with the body mass index, there being statistically significant differences between normal weight vs overweight vs obese patients, as well as between overweight and obese ones. Within the whole group and within the groups, both the left ventricle mass (g) as well as the left ventricle mass to body surface ratio (g/m²) are statistically significantly higher in patients with present diastolic dysfunction (E/A < 1). This indicates a relation between the presence of diastolic dysfunction, increased left ventricle mass and body mass index (p < 0.05).

Conclusions. Overweight and obese patients, unlike normal weight ones, present early cardiac changes, such as: a decrease of left ventricle ejection fraction, diastolic dysfunction, thickening of the interventricular septum, increase of the left ventricle mass both per se as well as in ratio to body surface.

Introduction: Reduced serum levels of paraoxonase 1 (PON1) activities are associated with diseases involving increased oxidative stress, such as acute coronary syndrome. We aimed to determine whether serum PON1 activities are a prognostic factor for one-year survival following ST-elevation myocardial infarction (STEMI).

Material and methods: We prospectively followed for one-year 75 patients diagnosed and treated for STEMI. Clinical, laboratory and imagistic data were gathered after coronary angiography. PON1 activities (paraoxonase, arylesterase, and lactonase) were assayed spectophotometrically on samples of heparinized plasma taken from the patients in a timeframe of maximum 20 minutes after coronary angiography.

Results: Increased mortality was linked to age (patients over 68 years), permanent atrial fibrillation or left ventricular ejection fraction (LVEF) <40% (associated with global hypokinesia, apical or septal akinesia), trivascular disease atherosclerosis, reduced PON1 activities (paraoxonase <18.4 IU/mL, arylesterase <12.6 IU/mL, lactonase <27.6 IU/mL), and glomerular filtration rate levels <54 mL/min/1.73m2. Multivariate survival analysis showed the independent prognostic role of age (HR 3.92; 95%CI 1.08-14.16; p=0.03), LVEF (HR 9.93; 95%CI 2.20-44.86; p=0.003) and arylesterase (HR 4.25; 95%CI 0.94-19.18; p=0.05) for one-year mortality.

Conclusion: Reduced arylesterase activity of PON1 is an independent predictor of one-year survival after acute myocardial infarction.
