ABSTRACT

Aim    Aortic stenosis increases left atrial (LA) pressure and may lead to its remodeling. This can cause supraventricular arrhythmia. The aim of this study was to determine if the size of the LA and the presence of atrial fibrillation are related to the prognosis of patients with aortic stenosis.Material and methods    Clinical evaluation and standard transthoracic echocardiographic studies were performed in 397 patients with moderate to severe aortic stenosis.Results    In all patients, LA dimension above the median (≥43 mm) was associated with a significantly higher risk of death [HR 1.79 (CL 1.06-3.03)] and a LA volume above the median of 80 ml was associated with a significantly higher risk of death [HR 2.44 (CI 1.12-5.33)]. The presence of atrial fibrillation was significantly associated with a higher risk of death (p <0.0001). The presence of atrial fibrillation [HR 1.69 (CI 1.02-2.86)], lower left ventricular ejection fraction [HR 1.23 (CI 1.04-1.45)], higher NYHA heart failure class [HR 4.15 (CI 1.40-13.20)] and renal failure [HR 2.10 (CI 1.31-3.56)] were independent risk factors of death in patients in aortic stenosis.Conclusion    The size and volume of the LA and the occurrence of atrial fibrillation are important risk factors for death in patients with aortic stenosis. The presence of renal dysfunction, low left ventricular ejection fraction, high NYHA functional class and atrial fibrillation are independent risk factors of poor prognosis in patients with aortic stenosis.

ABSTRACT

Introduction: Carotid artery stenting (CAS) using conventional (single-layer) stents is associated with worse clinical outcomes in diabetes mellitus (DM) vs. non-DM patients: an effect driven largely by lesion-related adverse events. CAS outcomes with MicroNet-covered stents (MCS) in diabetic patients have not been evaluated. Aim: To compare short- and long-term clinical outcomes and restenosis rate in DM vs. non-DM patients with carotid stenosis treated using MCS. Materials and Methods: In a prospective study in all-comer symptomatic and increased-stroke-risk asymptomatic carotid stenosis, 101 consecutive patients (age 51-86 years, 41% diabetics) underwent 106 MCS-CAS. Clinical outcomes and duplex ultrasound velocities were assessed periprocedurally and at 30 days/12 months. Results: Baseline characteristics of DM vs. non-DM patients were similar except for a higher prevalence of recent cerebral symptoms in DM. Type 1 and type 1+2 plaques were more prevalent in DM patients (26.7% vs. 9.8%, p = 0.02; 62.2% vs. 37.7%, p = 0.01). Proximal embolic protection was more prevalent in DM (60% vs. 36%; p = 0.015). 30-day clinical complications were limited to a single periprocedural minor stroke in DM (2.4% vs. 0%, p = 0.22). 12-month in-stent velocities and clinical outcomes were not different (death rate 4.8% vs. 3.3%; p = 0.69; no new strokes). Restenosis rate was not different (0% vs. 1.7%, p = 0.22). Conclusions: MCS may offset the adverse impact of DM on periprocedural, 30-day, and 12-month clinical complications of CAS and minimize the risk of in-stent restenosis. In this increased-stroke-risk cohort, adverse event rate was low both in DM and non-DM. Further larger-scale clinical datasets including extended follow-ups are warranted.

ABSTRACT

INTRODUCTION: Atrial septal defect (ASD) is the most common congenital cardiac anomaly diagnosed in adults. It often remains asymptomatic until the fourth or fifth decade of life. Significant left-to-right interatrial shunting is associated with the risk of heart failure, pulmonary hypertension and atrial fibrillation. Percutaneous ASD closure is a recognized method of treatment. AIM: To evaluate the clinical outcomes and physical capacity in patients undergoing transcatheter closure of ostium secundum ASD. MATERIAL AND METHODS: One hundred and twenty adult patients (75 females and 45 males) with a mean age of 43.1 ±13.3 (17-78) years who underwent transcatheter device closure of ostium secundum ASD were analyzed. Clinical evaluation and transthoracic color Doppler echocardiographic study were repeated in all patients before as well as 1 and 24 months after the procedure. To assess the physical capacity symptom-limited treadmill exercise tests with respiratory gas-exchange analysis were performed in all patients before the procedure and after 24 months of follow-up. RESULTS: The devices were successfully implanted in all patients. During 24 months of follow-up all patients showed significant clinical and spiroergometric improvement of exercise capacity, and a significant decrease of right heart chamber overload features on echocardiography. CONCLUSIONS: Transcatheter closure of ASD in patients with significant shunt resulted in significant clinical and hemodynamic improvement regardless of the baseline functional class.

ABSTRACT

INTRODUCTION: Early access to Emergency Medical Services determines survival in out-of-hospital cardiac arrest. However, a significant proportion of adults do not know the emergency phone number (EN) and no intervention has been proposed to improve it. Therefore, we aimed to assess prospectively the effectiveness of single advice from a physician on knowledge of the EN in adult population. MATERIALS AND METHODS: The study was conducted among participants of "Health, Alcohol and Psychosocial Factors in Eastern Europe" study. A total of 942 persons (aged 48-82 years) randomly selected from an urban population registry were interviewed and then instructed about the correct EN (the intervention group). After 12 months knowledge of the EN was assessed in the intervention group (n=716) and in matched control group (n=435). RESULTS: The correct EN was given by 498 (69.6%) participants at baseline and in 550 (76.8%) participants 12 months afterwards (p<0.001). At follow-up the knowledge of EN was higher by in intervention group than in controls (76.8% vs 70.6%, p=0.02). Factors associated with better educational effect were male sex (OR 1.49; 95% CI 1.04-2.1) and secondary or higher level of education (OR 1.44; 95% CI 1.08-1.91). CONCLUSIONS: We concluded that a single instruction about the EN from a physician increases its long-term knowledge and should be offered during medical visits.

ABSTRACT

BACKGROUND: The aim of this study was to prospectively perform ambulatory 24-h ECG monitoring to assess the effects of transcatheter closure of atrial septal defect (ASD). METHODS AND RESULTS: A total of 235 consecutive subjects (female, n=163; male, n=72; age, 44.6±14.4 years) were enrolled in the study, who were due undergo ASD closure. Holter monitoring was performed before procedure and at 1, 6 and 12 months of follow-up. During the procedure transient supraventricular arrhythmia occurred in 8 patients (3.4%), and bradycardia in 3 (1.3%). In 3 patients (1.3%) an episode of atrial fibrillation occurred in the first hour after the procedure. In 8 patients (3.4%) transient first-degree atrioventricular block was noted. A significant increase in number of supraventricular extrasystoles (SVES)/24 h was noted 1 month after the procedure (P<0.001). On multiple forward stepwise regression analysis, device size and fluoroscopy time had an influence on increase in number of SVES seen 1 month after the procedure (P<0.001). CONCLUSIONS: Transcatheter closure of ASD is associated with a transient increase in supraventricular premature beats and a small risk of conduction abnormalities and paroxysmal atrial fibrillation in early follow-up. Transcatheter closure of ASD does not reduce arrhythmia that appears prior to ASD closure. Larger device size and longer procedure time are associated with increased risk of supraventricular arrhythmia on early follow-up.

ABSTRACT

BACKGROUND: The study aimed to assess the level of plasma Endothelin-1 (ET-1) in patients before and after transcatheter closure of atrial septal defect (ASD) and to evaluate the usefulness of measuring ET-1 levels for the diagnosis and selection of candidates for ASD closure. METHODS: 80 patients (55 F, 25 M), mean age 42,2 ± 11,5 years were enrolled for an attempt at ASD closure. A group of 19 healthy volunteers, (12 F, 7 M) mean age 39.2 ± 9.15 served as controls. All ASD patients underwent: clinical and echocardiographic study and cardiopulmonary exercise test. ET-1 levels were measured before and after closure. Whole blood was collected from femoral artery and vein and from pulmonary artery during cardiac catheterization. RESULTS: ET-1 levels at peripheral artery and vein in ASD patients were significantly higher than in the volunteers (p < 0.0001). The ASD subjects with highest ET-1 level presented the larger area of right ventricle and right atrium and higher pulmonary artery systolic pressure(p < 0.05). The ASD subjects with lower ET-1 level demonstrated longer time of exercise and higher peak oxygen consumption (p < 0.05). There was a decrease of ET-1 at peripheral artery (5.128 ± 8.8 vs. 2.22 ± 6.2; p < 0.001) and at peripheral vein (4.401 ± 3.33 vs. 2.05 ± 1.35; p < 0.001) within 48 hours after ASD closure, as compared to the baseline data. After 6 and 12 months farther drop in ET-1 level was observed. CONCLUSIONS: 1. The level of ET-1 in ASD patients is elevated in compare to healthy subject.2. The significant reduction of ET-1 level is observed after percutaneous closure of ASD.3. Elevated level of ET-1 in patients with ASD is associated with right heart enlargement.4. Measurements of ET-1 may be a supplemental diagnostic tool and may be helpful in establishing indications for defect closure.

ABSTRACT

OBJECTIVE: Closure of an atrial septal defect in elderly patients is controversial. The aim of the study was to evaluate the outcomes of transcatheter closure of secundum atrial septal defects (ASDs) in elderly patients. PATIENTS AND METHODS: From a total of 488 patients with ASDs who underwent transcatheter closure, 75 patients aged over 60 years (45 female, 30 male) with a mean age of 65.3±15.7 (60-75) years were analyzed. All patients had an isolated secundum ASD with a mean pulmonary blood flow:systemic blood flow of 2.84±1.9 (1.5-3.9). Symptom-limited treadmill exercise tests with respiratory gas-exchange analysis and transthoracic color Doppler echocardiographic study, as well as quality of life measured using the Short Form (36) Health Survey (SF-36) were repeated in all patients before the procedure and after 12 months of follow-up. RESULTS: The atrial septal device was successfully implanted in all patients (procedure time 37.7±4.5 [13-59] minutes, fluoroscopy time 11.2±9.9 [6-40] minutes). There were no major complications. The defect echo diameter was 17.7±15.8 (12-30) mm. The mean balloon-stretched diameter of ASDs was 22.4±7.9 (14-34) mm. The diameter of the implanted devices ranged from 16 to 34 mm. Significant improvement of exercise capacity was noted at 6 and 12 months after the procedure. Exercise time within 6 months of ASD closure was longer (P<0.001) compared to baseline values, and also oxygen consumption increased (P<0.001). Seven quality-of-life parameters (except mental health) improved at 12-month follow-up compared to baseline data. The mean SF-36 scale increased significantly in 66 (88%) patients, with a mean of 46.2±19.1 (5-69). As early as 1 month after the procedure, a significant decrease of the right ventricular dimension and the right atrium dimension was observed (P<0.001). The right ventricular dimension decreased in 67 patients (89.3%). CONCLUSION: Closure of ASDs in elderly patients caused significant clinical and hemodynamic improvement after percutaneous treatment, which was maintained during long-term follow-up, justifying this procedure in old age.

ABSTRACT

INTRODUCTION: Closure of the atrial septal defect in patients with insignificant shunt is controversial. AIM: To evaluate the outcomes of transcatheter closure of atrial septal defect (ASD) in symptomatic patients with borderline shunt. MATERIAL AND METHODS: One hundred and sixty patients (120 female, 40 male) with a mean age of 30.1 ±16.2 (20-52) years with a small ASD who underwent transcatheter closure were analyzed. All patients had a small ASD with Qp: Qs ratio ≤ 1.5, mean 1.2 ±0.9 (1.1-1.5) in echo examination. Cardiopulmonary exercise tests, clinical study, transthoracic echocardiographic study as well as quality of life (QoL) (measured using the SF36 questionnaire (SF36q)) were repeated in all patients before and after the procedure. RESULTS: The devices were successfully implanted in all patients. After 12 months of ASD closure, all the patients showed a significant improvement of exercise capacity (oxygen consumption - 21.9 ±3.1 vs. 30.4 ±7.7, p > 0.001). The QoL improved in 7 parameters at 12-month follow-up. The mean SF36q scale increased significantly in 141 (88.1%) patients of mean 43.2 ±20.1 (7-69). A significant decrease of the right ventricular area (20.3 ±1.3 cm(2) vs. 18.3 ±1.2 cm(2), p < 0.001) and the right atrial area (15.2 ±1.9 cm(2) vs. 12.0 ±1.6 cm(2), p < 0.001) was observed at 12-month follow-up. CONCLUSIONS: Closure of ASD in the patients with insignificant shunt resulted in significant durable clinical and hemodynamic improvement after percutaneous treatment.

ABSTRACT

BACKGROUND: Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE).The goal of this study was to evaluate the feasibility of transcranial color Doppler (TCD) and its diagnostic sensitivity compared with TEE. METHODS: We investigated 420 patients admitted to our department with cryptogenic stroke, transient ischemic attacks or other neurological symptoms. All patients underwent TCD and TEE evaluation. TCD and TEE examinations were performed according to a standardized procedure: air-mixed saline was injected into the right antecubital vein three times, while the Doppler signal was recorded during the Valsalva maneuver. During TCD the passage of contrast into the right-middle cerebral artery was recorded 25 seconds following the Valsalva maneuver. RESULTS: We detected a right-to-left shunt in 220 patients (52.3%) and no-shunts in 159 patients (37.9%) with both TCD and TEE. In 20 (4.8%) patients TEE did not reveal contrast passage which was then detected by TCD. In 21 (5.0%) patients only TEE revealed a PFO. The feasibility of both methods was 100%. TCD had a sensitivity of 95% and a specificity of 92% in the diagnosis of PFO. CONCLUSIONS: TCD has a relatively good sensitivity and specificity. TCD and TEE are complementary diagnostic tests for PFO, but TCD should be recommended as the first choice for screening because of its simplicity, non-invasive character, low cost and high feasibility.

ABSTRACT

BACKGROUND: Echocardiography has emerged as the test of choice for the evaluation of cardiac diseases. AIM: To assess the prevalence of a spectrum of cardiac abnormalities detected by echocardiography in a representative sample of an urban adult population. METHODS: Transthoracic echocardiography was performed in a random sample of 511 men (47%) and women (53%) aged 48-76 years selected from population registers in Krakow. Body surface area (BSA) was used to adjust echocardiographic parameters for variations in body size. Disease history and cardiovascular risk factors were assessed in all patients. RESULTS: Men smoked more frequently than women and had higher blood pressure and triglycerides and lower high density lipoprotein cholesterol. The most common finding was increased left ventricular (LV) end-diastolic diameter (EDd) (37%), followed by mitral (32%), aortic (24%), or tricuspid (17%) regurgitations, LV posterior wall (24.1%) and interventricular septum (17.5%) thickening, increased indexed LVEDd (23%), increased left atrial diameter (LAd; 15.7%), reduced LV ejection fraction (LVEF; 15.3%), segmental wall motion abnormalities (13.9%), increased indexed LAd (8.8%), dilation of the ascending aorta (8%), enlargement of the right ventricle (RV) (2%) and elevation of RV systolic pressure (0.6%). When adjusted for main cardiovascular risk factors and the presence of coronary artery disease, male sex was associated with a higher prevalence of enlargement of LV (LVEDd/BSA): OR = 1.8 (1.1-2.9), dilation of ascending aorta (aortic diameter/BSA): OR = 2.7 (1.3-5.8), and LA (LA/BSA) = OR 2.7 (1.3-5.6), as well as a decrease of LVEF: OR = 3.6 (1.9-6.5). CONCLUSIONS: Approximately a quarter of urban adults aged 48 to 76 can be expected to have some abnormalities on echocardiographic examination. Some of these abnormalities such as aortic dilation, LA enlargement, LV enlargement and decreased LVEF are more frequently found in males than in females, even after adjustment for BSA, main cardiovascular disease risk factors, and the presence of coronary artery disease. The use of raw instead of indexed LAd and LVEDd over estimates the prevalence of LA and LV enlargement.

ABSTRACT

BACKGROUND: Idiopathic pulmonary artery (PA) hypertension (IPAH) is associated with severe PA remodelling. Although the resulting increase in pulse wave velocity (PWV) might be of major pathophysiological relevance, little is known about PA-PWV in IPAH. The aim of this study was to characterize PA-PWV and its predictors in patients with IPAH. METHODS: We studied 26 consecutive patients with incident IPAH aged 55.0 (45.0-66.0) years (62% female) and 10 control subjects without pulmonary hypertension. PA-PWV was measured invasively; PA wall thickness and diameter were assessed using intravascular and transthoracic ultrasonography. RESULTS: PA-PWV was higher in IPAH than in control subjects (10.0 [7.5-14.0] m/s vs 3.5 [1.9-4.0] m/s; P < 0.001) as was also PA diameter and PA wall thickness. In IPAH patients, in univariate analysis PA-PWV was greater in men than in women and in patients with body mass index (BMI) < 25 kg/m(2) than with BMI ≥ 25 kg/m(2) and correlated positively with symptomatic disease duration, mean PA pressure, pulmonary vascular resistance, creatinine level, and negatively with low-density lipoprotein (LDL) cholesterol and triglyceride level but not with PA diameter or PA wall thickness. In multiple regression analysis mean PA pressure, LDL cholesterol level and BMI < 25 kg/m(2) were the main predictors of PA-PWV in IPAH patients (R(2) = 77%; P < 0.001). CONCLUSIONS: PA-PWV is increased in IPAH patients. High PA pressure, low LDL cholesterol level, and BMI < 25 kg/m(2) explain most of its variability in this group.

ABSTRACT

BACKGROUND: Effective management of acute myocardial infarction (AMI) is limited by patient delay in calling an ambulance. We aimed to assess knowledge related to a patient-dependant phase of AMI and its determinants in adults. METHODS: Questionnaire survey was conducted among a random sample of 942 men (48%) and women (52%) aged 63.50 ± 6.50 selected from population registers in Cracow (Poland). Questions from the Behavioral Risk Factor Surveillance System were used to assess knowledge of AMI symptoms. The respondents were further asked about the first thing they would do in response to AMI symptoms, the emergency phone number and whether a doctor advised them about AMI. RESULTS: All suggested AMI symptoms were recognized by 51 (5.4%) respondents. More persons would call an ambulance in response to AMI symptoms in another person than if they appear in themselves (87.4% vs. 74.4%, P = 0.02). Only 644 (68%) participants knew the emergency phone number and 104 (11%) were advised about AMI by their doctors. Such advice was associated with higher rates of knowledge of AMI symptoms and the emergency phone number but not with a declaration of the appropriate reaction to AMI symptoms. Participants after AMI did not represent better knowledge of a patient-dependant phase of AMI but paradoxically less frequently than other persons declared calling an ambulance in response to AMI symptoms. CONCLUSION: Improvement in knowledge and attitudes related to a patient-dependant phase of AMI is needed in adults even if they experienced AMI before. A routine advice from a doctor may contribute significantly to this improvement.

ABSTRACT

OBJECTIVE: The aim of study was to assess whether activation of blood coagulation and platelets is enhanced in aortic stenosis (AS) and if so, to determine factors that might modulate these processes. PATIENTS/METHODS: Seventy-five patients with AS (48 males, 27 females, aged 65+/-10 years) were enrolled in the study. A control group comprised 75 age- and sex-matched subjects. We determined markers of thrombin generation (thrombin-antithrombin complex [TAT], prothrombin fragment 1+2 [F1+2]), platelet activation (soluble CD40 ligand [sCD40L], beta-thromboglobulin [beta-TG], P-selectin) in peripheral blood plasma. The extent of atherosclerosis in the carotid and coronary arteries was assessed as a potential confounding factor. RESULTS: Mean concentrations of thrombin and platelet markers were higher approximately two-fold in the AS group than in controls (p<0.005 for all comparisons). Maximal gradient was positively associated with TAT (r=0.61, p<0.001), F1+2 (r=0.60, p<0.001), sCD40L (r=0.52, p<0.01) and beta-TG (r=0.70, p<0.001). Aortic valve area (AVA) negatively associated only with one platelet marker, beta-TG (r=-0.30, p<0.05). The presence of concomitant atherosclerotic plaque in the carotid (in 65% of patients) or coronary arteries (in 43% of patients) did not influence thrombin generation and platelet activation in patients with AS. CONCLUSIONS: AS predisposes to prothrombotic state. Maximal gradient as an index of turbulent flow associated with activation of coagulation and platelets. In contrast, the small aortic valve area was not closely related to these parameters.
