Artery disease can be identified from ankle-brachial index (peripheral artery disease), pulse wave velocity (arterial stiffness), carotid intima media thickness (atherosclerosis) and flow-mediated dilation (endothelial disfunction). Arterial stiffness is a marker of cardiovascular disease associated with cardiovascular events. Increased vascular ageing is the acceleration of arterial stiffness inappropriate for the given chronological age. Treatment of early vascular ageing seems to be important if we target on primary cardiovascular prevention...

OBJECTIVE: The appropriateness of endovascular aneurysm repair (EVAR) of uncomplicated abdominal aortic aneurysm depends on the risk-benefit ratio, particularly in elderly patients with short life expectancy. The aim of this study was to assess the efficacy of EVAR in >80-year-old patients by evaluating their postoperative survival and analyzing the possible predictors of late mortality. METHODS: All consecutive patients aged >80 years undergoing elective EVAR from 2006 to 2015 were prospectively evaluated...

PURPOSE: Continuous peripheral pulse oximetry for monitoring adequacy of oxygenation is probably the most important technological advance for patients' monitoring and safety in the last decades. Pulse oximetry has the disadvantage of measuring the peripheral circulation, and the only mean to measure oxygen content of the central circulation is by invasive technology. Determination of blood oxyhaemoglobin saturation in the retinal vessels of the eye can be achieved noninvasively through spectrophotometric retinal oximetry which provides access to the central nervous system circulation...

INTRODUCTION: The implications of prosthesis-patient mismatch (PPM) in the context of transcatheter aortic valve implantation (TAVI) are still controversial. The objective of our study was thus to investigate the incidence and prognostic impact of PPM after TAVI. METHODS: Our analysis included 613 TAVI patients in whom the indexed effective orifice area (iEOA) after TAVI was obtained in vivo using echocardiography. Prosthesis sizing was guided by pre-procedural ECG-gated computed tomography...

Diabetes increases the risk of different kidney diseases. The most important is diabetic nephropathy, however, ischemic kidney disease, chronic pyleonephritis and papilla necrosis may also develop. The prognosis of diabetic nephropathy has improved recently, however, it is still the primary cause of dialysis and transplantation. Cardiovascular diseases predict mostly mortality in diabetic patients, however, cerebrovascular insults and peripheral obstructive arterial diseases necessitating lower limb amputations are also important...

BACKGROUND: The use of two bilateral internal thoracic artery grafting (BITA) was shown to lead to survival benefit. However, operators are reluctant to use BITA with peripheral vascular disease (PVD) because of concerns of increased rates of sternal wound infection and lack of studies supporting survival benefit compared with single internal thoracic artery (SITA) grafting. The aim of this study is to compare outcome BITA grafting versus of SITA and vein grafts in PVD patients. PATIENTS AND METHODS: Six hundred and twenty-one PVD patients who underwent BITA between 1996 and 2011 were compared with 372 patients who underwent SITA...

PURPOSE: Timing and ideal reconstructive approach in deep sternal wound infection (DSWI) and mediastinitis still remain controversially debated. We present our own combined surgical strategy of bilateral pectoralis major muscle flap (BPMMF) or omental flap (OF) transposition. METHODS: Between July 2010 and July 2016, poststernotomy patients with DSWI and mediastinitis underwent a secondary wound closure with modified BPMMF (Group A, center for disease control class (CDC)-II, n = 21; Group B, CDC-III, n = 20) or with OF (Group C, CDC-III, n = 19) following vacuum-assisted closure (VAC)...

BACKGROUND: Complete revascularization is the gold standard of coronary artery bypass grafting (CABG). However, the rationale for revascularization of all diseased vessels is questionable. We aimed at evaluating the impact of multiple versus single grafts in each diseased coronary territory in the long-term survival and incidence of major adverse cardiac and cerebrovascular events (MACCE). METHODS: From January/00 to November/15, 5.694 consecutive patients were submitted to isolated CABG, of whom 4...

Objective Buerger's disease is one of the worst diseases causing peripheral artery occlusions (especially lower extremity) with increased morbidity and mortality. Endovascular treatment of the diseased arteries gains preference over bypass surgery nowadays. Here, we aimed to present the clinical outcomes of 16 consecutive Buerger's disease patients underwent extended endovascular recanalization which is a new technique to restore direct blood flow to at least one foot artery, with the performance of angioplasty for each tibial and foot artery obstructions...

BACKGROUND: Coronary artery bypass surgery (CABG) is a common surgical treatment for ischemic heart disease. Little is known about the long-term costs of conducting the surgery on-pump or off-pump. METHODS: As part of the Randomized On/Off Bypass follow-up study, we followed 2,203 participants randomized to on-pump (n = 1,099) and off-pump (n = 1,104) CABG for 5 years using Department of Veterans Affairs and Medicare administrative data. We examined annual costs through 5 years, standardized to 2016 dollars, using multivariate regression models, controlling for site and baseline patient factors...

OBJECTIVE/BACKGROUND: The development of an abdominal aortic aneurysm (AAA) involves extensive extracellular matrix remodelling, leading to aortic wall weakening. This process is mediated by proteases, including cysteinyl cathepsins. Cystatins are their endogenous inhibitors. This study tested whether plasma cystatin B levels in patients with AAA differed from those of healthy controls. METHODS: Plasma samples from patients with AAA and age matched controls were selected from the Viborg Vascular (VIVA) screening trial for AAA...

AIM: Peripheral artery disease (PAD) is a manifestation of atherosclerosis with poor prognosis. It is generally complicated by vascular calcification, which is located either in the intima as patchy infiltrates; or circumferentially in the media, also known as medial arterial calcification (MAC). Obstructive PAD is reflected by low anklebrachial index (ABI ≤ 0.9), whereas MAC is revealed by high ABI (ABI >1.4). Considering the increase in cardiovascular mortality at both ends of the ABI spectrum, this study aimed to explore the underlying pathology through cytokines with established prognostic significance; namely pentraxin-3(PTX3), high sensitivity C-reactive protein (hsCRP), copeptin, soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), NT-proBNP, and neopterin...

OBJECTIVE: Obstructive sleep apnea (OSA) is common in peripheral arterial disease (PAD) and associates with high mortality after surgery. Since abnormal heart rate variability (HRV) is predictive of postoperative complications, we investigated the relations of HRV with PAD, OSA and major adverse cardiovascular and cerebrovascular events (MACCE). MATERIALS AND METHODS: Seventy-five patients (67±9 years) scheduled for sub-inguinal revascularization and 15 controls (63±6 years) underwent polysomnography and HRV analyses...

Tubulointerstitial fibrosis (TIF) is a hallmark of chronic kidney disease resulting from diverse etiologies and predicts severity and progression of the kidney disease. To investigate the pathogenesis of TIF, complete unilateral ureteral obstruction (UUO) is the most widely used animal model. However, UUO precludes evaluation of renal function. In the present study, we created a rat model of chronic partial ureteral obstruction (PUO), which allowed assessment of renal function at different intervals after obstruction...

BACKGROUND: Patients with COPD are frequently diagnosed with cardiovascular disease. Peripheral endothelial dysfunction is an underlying mechanism and can be used as an early marker of cardiovascular impairment. To date, little is known on the association between peripheral endothelial dysfunction, cardiovascular risk factors and measurements of exercise capacity in patients with COPD. Therefore, we aimed to determine the relation between endothelial function and patient characteristics, cardiovascular risk factors and (micro)vascular and functional performance in patient with CODP...
