Background: The prevalence of heart failure (HF) is increasing rapidly with high readmission rates, mainly due to fluid retention. Ultrafiltration (UF) is a mechanical method for removing fluids. Introduced only recently in Israel, the skill and experience required for outpatient congested HF patients are scarce.

Objectives: To evaluate the feasibility and safety of UF therapy in congested HF patients in outpatient clinics under a strict protocol of monitoring and therapy that we developed.

Methods: Between April and September 2013 we applied UF in our outpatient clinic to seven chronically congested HF patients with NYHA III-IV who did not respond adequately to diuretics. We administered a total of 38 courses.

Results: On average, 1982 ml fluid per course was removed without significant adverse events and with patients' subjective feeling of improvement. Only two courses were interrupted prematurely due to mechanical problems but were completed without harm to the patients.

Conclusions: Under appropriate professional medical supervision, UF therapy in an outpatient setting is a safe and effective procedure and serves as an additional tool for managing congested HF patients who do not respond adequately to diuretics.

Background: Rapid reperfusion of an infarct-related artery is crucial for the successful treatment of ST elevation myocardial infarction. Every effort should be made to shorten door-to-balloon time.

Objectives: To investigate whether bypassing the emergency room (ER) has a positive influence on door-to-balloon time in patients presenting with ST elevation myocardial infarction (STEMI) and whether the reduction in door-to-balloon time improves patients’ clinical outcome.

Methods: We analyzed data of 776 patients with STEMI[1] from the 2004 and the 2006 Acute Coronary Syndrome Israeli Survey (ACSIS) registry. The ACSIS[2] is a biennial survey on acute myocardial infarction performed in all 25 intensive cardiac care units in Israel during a 2-month period. Twenty-five percent of patients (193 of 776) arrived directly to the intensive cardiac care unit (ICCU) and 75% (583 of 776) were assessed first in the ER[3]. We compared door-to-balloon time, ejection fraction, 30 days MACE (major adverse cardiac and cerebrovascular events) and 30 days mortality in the two study groups.

Results: There was significantly shorter door-to-balloon time in the direct ICCU group as compared with the ER group (45 vs. 79 minutes, P < 0.002). Patients in the direct ICCU group were more likely to have door-to-balloon time of less than 90 minutes in accordance with ACC/AHA guidelines (88.7% vs. 59.2%, P < 0.0001). Moreover, patients in the direct ICCU group were less likely to have left ventricular ejection fraction < 30% (5.4% vs. 12.2%, P = 0.045) and less likely to have symptoms of overt congestive heart failure. Lastly, 30 days MACE[4] was significantly lower in the direct ICCU group (22 vs. 30%, P < 0.004).

Conclusions: There is significant reduction of the door-to-balloon time in the direct ICCU admission strategy. This reduction translates into improvement in clinical outcome of patients. It is reasonable to apply the direct ICCU strategy to patients with STEMI.

Background: Renal artery stenosis is one of the most frequent causes of secondary hypertension. Appropriate methods for screening, diagnosis and therapy are currently under debate.

Objectives: To evaluate and recommend methods for screening and diagnosing renal artery stenosis, and to assess the clinical outcomes of renal artery stenting.

Methods: A total of 450 patients undergoing non-emergent coronary angiography fulfilled the selection criteria for selective renal arteriography; those with severe (luminal narrowing ≥ 70%) renal artery stenosis underwent percutaneous transluminal renal angioplasty with renal artery stenting.

Results: Of 166 patients (36.9%) with renal artery stenosis, 41 (9.1%) had severe stenosis that required renal artery stenting, and 83% had ostial renal stenosis. The primary success rate was 100% and there were no complications. During the follow-up period, two patients required a second PTRA[1]. After stent deployment, significant reductions were observed in systolic and diastolic pressures (P < 0.001 and P = 0.01, respectively) and in the number of antihypertensive drugs used by the patients (P < 0.001). These reductions were sustained during follow-up. Hypertension was cured (systolic blood pressure < 130 mmHg) in 9 (21.4%) and improved in 27 (64.3%) patients. Plasma creatinine did not change significantly.

Conclusions: Selective renal angiography is an effective diagnostic tool for identifying symptomatic cases of renal artery stenosis in patients undergoing coronary angiography. Our finding of a high success rate and low complication rate supports the use of primary renal artery stenting in symptomatic patients with renal artery stenosis.

Background The temporal behavior of the coronary microcirculation in acute myocardial infarction may affect outcome. Diastolic deceleration time and early systolic flow reversal derived from coronary artery blood flow velocity patterns reflect microcirculatory function.

Objectives To assess left anterior descending coronary artery flow velocity patterns using Doppler transthoracic echocardiography after primary percutaneous coronary intervention, in patients with anterior AMI[1].

Methods Patterns of flow velocity patterns of the LAD[2] were obtained using transthoracic echocardiography-Doppler in 31 consecutive patients who presented with anterior AMI. Measurements were done at 6 hours, 36–48 hours, and 5 days after successful PPCI[3]. Measurements of DDT[4] and pressure half times (Pt½), as well as observation for ESFR[5] were performed.

Results In the first 2 days following PPCI, the average DDT, 600 ± 340 msec, were shorter than on day 5, 807 ± 332 msec (P < 0.012). FVP[6] in the first 2 days were dynamic and bidirectional: from short DDT (< 600 msec) to long DDT (> 600 msec) and vice versa. On day 5 most DDTs became longer. Pt½ at 6 hours was not different than at day 2 (174 ± 96 vs. 193 ± 99 msec, P = NS) and became longer on day 5 (235 ± 98 msec, p = 0.012). Bidirectional patterns were also observed in the ESFR in 6 patients (19%) at baseline, in 4 (13%) at 36 hours, and in 2 (6.5%) on day 5 after PPCI.
