RESUMO
Aim To assess the onset of early left ventricular (LV) systolic and diastolic function impairment and the subclinical atherosclerosis following chemotherapy in patients diagnosed with acute myeloid leukemia (AML). MATERIALS AND METHODS: Thirty patients diagnosed with AML with no cardiac history, having LV ejection fraction (LVEF) >50%, were evaluated at baseline and 6 months after starting four cycles of chemotherapy. We measured LV function, global longitudinal strain and subclinical atherosclerosis markers: intima-media thickness (IMT), arterial stiffness aortic pulse wave velocity (PWVAo) and ankle-brachial index (ABI). RESULTS: LVEF had decreased at 6 months after treatment initialization (p<0.001), the same changes being observed for LV fraction shortening (p<0.001), mitral annular plane systolic excursion and S' wave (p<0.001 and p<0.05). Bilateral IMT and PWVAo significantly increased, 12 out of 30 patients (40%) had LVEF ≤50% after 6 months of chemotherapy, five of them receiving daunorubicin at more than 500 mg/m2/injection. CONCLUSION: LV function is impaired after 6 months of chemotherapy, with early changes of subclinical atherosclerosis becoming evident.

AIM: To evaluate the impact of physical training on central hemodynamic parameters and elasticity of large arteries in hypertensive patients. PATIENTS AND METHODS: A total of 129 hypertensive patients were divided into two groups: group A followed lifestyle changes and physical training; and group B acted as a control group; seven parameters were recorded: Pulse wave velocity (PWVao), systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), central aortic systolic blood pressure (SBPao), aortic diastolic blood pressure (DBPao), and central aortic pulse pressure (PPao). RESULTS: The difference between values at 4 months and baseline (Δ) were as follows: ΔPWVao was -1.02 m/s (p<0.001) versus 0.17 m/s (p=0.035), ΔSBPao was -9.6 mmHg (p=0.009) versus 1.6 mmHg (p=0.064), and ΔPPao was -6.8 mmHg (p<0.001) versus 3.2 mmHg, (p=0.029) in group A versus B, respectively. CONCLUSION: Exercise training improves SBP, PP, SBPao, PPao and may delay arterial ageing.

Cardiovascular risk is an important factor for increased morbidity and mortality in patients with ankylosing spondylitis. The aim of this study is to assess arterial stiffness in relation to the disease activity and functional limitation in patients with ankylosing spondylitis. Twenty-four patients (mean age 45.8 ± 11.7 years) suffering of ankylosing spondylitis (disease duration 11.1 ± 5.1 years) and 24 gender and age-matched healthy controls were included in the study. Clinical, biological, and functional status of ankylosing spondylitis patients was recorded. Arterial stiffness was assessed by measuring pulse wave velocity (PWV) and pulse wave analysis (PWA) was performed using applanation tonometry. We found significant differences between ankylosing spondylitis patients and healthy controls in regard to PWV (p = 0.047), aortic augmentation pressure-AP (p = 0.028), augmentation index-AIx (p = 0.038) and aortic augmentation index adjusted for heart rate-AIx75 (p = 0.011). PWV and AIx75 were significantly associated with the disease functioning score-BASFI (p = 0.012, r = 0.504; p = 0.041, r = 0.421). Aortic AP and augmentation indexes (AIx and AIx75) were all associated to ASDAS score (p = 0.028, r = 0.448; p = 0.005, r = 0.549; p = 0.025, r = 0.455). Our study showed that ankylosing spondylitis patients have a higher arterial stiffness than the age-matched controls, leading to an increased cardiovascular risk. We found that arterial stiffness is positively associated with disease activity and functional impairment. Chronic spondiloarthropaties should be screened for arterial stiffness, even in the absence of traditional cardiovascular risk factors, in order to benefit from primary prevention measures.

OBJECTIVE: Evaluating smoking incidence, the compliance to smoking cessation recommendation and benefits of quitting smoking in coronary patients included in EuroAspire III Romania survey. MATERIALS AND METHODS: We evaluated the acute cardiovascular events (MACE) incidence in 530 consecutive coronary patients (> or = 18 years and < 80 years at the time ofidentification) with first or recurrent clinical diagnosis or treatments for coronary heart disease, retrospectively identified from diagnostic registers or hospital discharge lists. The coronary events for hospital admission were: elective or emergency coronary artery by-pass graft (CABG), elective or emergency percutaneous transluminal coronary angioplasty (PTCA), acute myocardial infarction (AMI) and unstable angina (UA). The starting date for identification was not less than 6 months and not more than 3 years prior to the expected date ofinterview. Patients were divided in three groups according to their condition of smoker (smoking at interview moment), ex-smoker (quitting smoking prior to interview moment) and no smoker (never smoking). RESULTS: Smoking incidence before hospital admission for coronary event was 68.3% and 10% after hospital discharge. Prior the coronary event, percentage of male smokers (77.15%) predominated by female smokers (42.64%) - p<0.05, OR=4.54. Male smokers (67.25%) were more compliant to smoking cessation recommendation compared to females (32.35%) - p=0.04, OR=2.16; there was no significant difference between the two sexes concerning smoking incidence at interview moment (p>0.05). Patients who continued smoking after hospital discharged presented an increased frequency of MACE compared to non smokers (p=0.043, OR=1.98). Also, patients who continued smoking till hospitalization for coronary event, presented a higher risk compared to non smokers concerning re-intervention by PTCA (p=0.017, OR=4.28) and AMI incidence (p=0.01, OR=4.89). The MACE incidence was higher in active smokers versus passive smokers, but there was no significant differences between the two groups (p>0.05). CONCLUSION: Majority of coronary patients renounced smoking after their first experience with cardiovascular events, a small part continued smoking. Patients who continued smoking after the acute event had higher incidence of MACE compared to non-smokers or ex-smokers (p<0.05). Also, MACE incidence was higher in active smokers versus passive but the difference was not significant between the two groups (p>0.05).
