Background: Neutrophil-to-lymphocyte ratio (NLR) is a simple and cost-effective marker of inflammation. This marker has been shown to predict cardiac arrhythmias, progression of valvular heart disease, congestive heart failure decompensation, acute kidney injury, and mortality in cardiovascular patients. The pathologic process of aortic stenosis includes chronic inflammation of the valve and therefore biomarkers of inflammation might offer additive prognostic value.

Objectives: To evaluate NLR and its association with long term mortality in transcatheter aortic valve implantation (TAVI) patients.

Methods: We evaluated data of 1152 consecutive patient from the Tel Aviv Medical Center TAVI registry who underwent TAVI. Data included baseline clinical, demographic, and echocardiographic findings; procedural complications; and post-procedure mortality. Patients were compared by using the median NLR value (4.1) and evaluated for long-term mortality.

Results: Patients with NLR above the median had higher mortality rates (26.4% vs. 16.3%, P < 0.001) at 3 years post-procedure. A multivariable analysis found NLR to be an independent risk factor for mortality (hazard ratio = 1.47, 95% confidence interval 1.09–1.99, P = 0.013). In addition, high NLR was linked to complicationsduring and after the procedure.

Conclusion: NLR is an independent prognostic marker among TAVI patients. This marker may represent an increased inflammatory response and should be added to previous known prognostic factors.

Background: Acute pulmonary embolism (PE) is considered to be one of the most common cardiovascular diseases with considerable mortality. Conflicting data imply possible role for echocardiography in assessing this disease.

Objectives: To determine which of the echo parameters best predicts short-term and long-term mortality in patients with PE.

Methods: We prospectively enrolled 235 patients who underwent computed tomography of pulmonary arteries (CTPA) and transthoracic Echocardiography (TTE) within < 24 hours. TTE included a prospectively designed detailed evaluation of the right heart including right ventricular (RV) myocardial performance index (RIMP), RV end diastolic and end systolic area, RV fractional area change, acceleration time (AT) of pulmonary flow and visual estimation. Interpretation and performance of TTE were blinded to the CTPA results.

Results: Although multiple TTE parameters were associated with PE, all had low discriminative capacity (AUC < 0.7). Parameters associated with 30-day mortality in univariate analysis were acceleration time (AT) < 81 msec (P = 0.04), stroke volume < 44 cc (P = 0.005), and RIMP > 0.42 (P = 0.05). The only RV independent echo parameter associated with poor long-term prognosis (adjusted for significant clinical, and routine echo associates of mortality) was RIMP (hazard ratio 3.0, P = 0.04). The only independent RV echo parameters associated with mortality in PE patients were RIMP (P = 0.05) and AT (P = 0.05). Addition of RIMP to nested models eliminated the significance of all other parameters assessing RV function.

Conclusions: Doppler-based parameters like pulmonary flow AT, RIMP, and stroke volume, have additive value in addition to visual RV estimation to assess prognosis in patients with PE.

Background: Patients with right bundle branch block (RBBB) prior to transcatheter aortic valve implantation (TAVI) are at high risk for immediate post-procedural heart block and long-term mortality when discharged without a pacemaker.

Objectives: To test whether prophylactic permanent pacemaker implantation (PPI) is beneficial.

Methods: Of 795 consecutive patients who underwent TAVI, 90 patients had baseline RBBB. We compared characteristics and outcomes of the prophylactic PPI with post-TAVI PPI. Need for pacing was defined as  greater than 1% ventricular pacing.

Results: Forty patients with RBBB received a prophylactic PPI (group 1), and in 50 the decision was based on standard post-procedural indications (group 2). There were no significant differences in clinical baseline characteristics. One patient developed a tamponade after a PPI post-TAVI. A trend toward shorter hospitalization duration in group 1 patients was observed (P = 0.06). On long-term follow-up of 848 ± 56 days, no differences were found in overall survival (P = 0.77), the composite event-free survival of both mortality and hospitalizations (P = 0.66), or mortality and syncope (P = 0.65). On multivariate analysis, independent predictors of the need for pacing included baseline PR interval increase of 10ms (odds ratio [OR] 1.21 per 10 ms increment 95% confidence interval [95%CI] 1.02–1.44, P = 0.028), and the use of new generation valves (OR 3.92, 95%CI 1.23–12.46, P = 0.023).

Conclusions: In patients with baseline pre-TAVI RBBB, no outcome differences were found with prophylactic PPI. On multivariate analysis, predictors of the need for pacing included baseline long PR interval, and the use of newer generation valves.

Abstract

Background: In the era of primary percutaneous coronary intervention (PPCI), information on the incidence and prognostic significance of high degree atrioventricular block (AVB) in ST elevation myocardial infarction (STEMI) patients is limited.

Objectives: To assess the incidence, time of onset, predictors and prognostic significance of high degree AVB in a large cohort of consecutive STEMI patients undergoing PPCI.

Methods: We retrospectively studied 1244 consecutive STEMI patients undergoing PPCI. Patient records were reviewed for the presence of high degree AVB, its time of occurrence and relation to in-hospital complications, as well as long-term mortality over a 5 year period.

Results: High degree AVB was present in 33 patients (3.0%), in 25 (76%) of whom the conduction disorder occurred prior to PPCI. Twelve patients (36%) required temporary pacing, all prior to or during coronary intervention, and all AVB resolved spontaneously before hospital discharge. AVB was associated with a significantly higher 30 day (15 % vs. 2.0%, P = 0.001) and long-term mortality rate (30% vs. 6.0%, P < 0.001). Time of AVB had no effect on mortality. In a multivariate regression model, AVB emerged as an independent predictor for long-term mortality (hazard ratio 2.8, 95% confidence interval 1.20–6.44, P = 0.001).

Conclusions: High degree AVB remains a significant prognostic marker in STEMI patients in the PPCI era, albeit transient.

 Background: Transcatheter aortic valve implantation (TAVI) has recently become an alternative to surgical aortic valve replacement in selected patients with high operative risk.

Objectives: To investigate the 30 day clinical outcome of the first 300 consecutive patients treated with transfemoral TAVI at the Tel Aviv Medical Center.

Methods: The CoreValve was used in 250 patients and the Edwards-Sapien valve in 50 patients. The mean age of the patients was 83 ± 5.3 years (range 63–98 years) and the mean valve area 0.69 ± 0.18 cm2 (range 0.3–0.9 cm2); 62% were women.

Results: The procedural success rate was 100%, and 30 day follow-up was done in all the patients. The average Euro-score for the cohort was 26 ± 13 (range 1.5–67). Total in-hospital mortality and 30 day mortality were both 2.3% (7 patients). Sixty-seven patients (22%) underwent permanent pacemaker implantation after the TAVI procedure, mostly due to new onset of left bundle brunch block and prolonged PR interval or to high degree atrioventricular block. The rate of stroke was 1.7% (5 patients). Forty-one patients (13.7%) had vascular complications, of whom 9 (3%) were defined as major vascular complications (according to the VARC definition).

Conclusions: The 30 day clinical outcome in the first 300 consecutive TAVI patients in our center was favorable, with a mortality rate of 2.3% and low rates of stroke (1.7%) and major vascular complications (3%).

Background: Erectile dysfunction is associated with treatable cardiovascular risk factors; therefore, screening for erectile dysfunction and its cardiovascular risk factors is of clinical importance.

Objectives: To detect erectile dysfunction cases and assess their severity among military personnel.

Methods: The Sexual Health Inventory for Men questionnaire was handed out to military personnel aged 25–55 years during routine examinations.

Results: A total of 19,131 men, with a mean age of 34.0 ± 7.1 years, participated in routine physical examinations during the years 2001–2005. More than half of them (n=9956, 52%) completed the SHIM[1] questionnaire. No significant differences were found between those who completed the SHIM questionnaire and those who did not, in terms of mean age, mean body mass index, and prevalence of cardiovascular risk factors. One out of every four men (25.2%) suffered from erectile dysfunction, which was mild in 18.9%, mild to moderate in 4.4%, moderate in 1.1% , and severe in 0.7%. Even though treatable cardiovascular risk factors were quite prevalent in the study group (45.2% of them suffered from dyslipidemia, 25.6% smoked, 4.2% suffered from essential hypertension, and 1.6% from diabetes mellitus), erectile dysfunction was significantly associated with age and diabetes mellitus alone (P < 0.0001).

Conclusions: There is a high prevalence of erectile dysfunction and associated treatable cardiovascular risk factors in Israeli men aged 25–55, especially those with diabetes.
