RESUMO
Aim: Transfemoral Trans-catheter Aortic Valve Replacement (TF-TAVR) is a safe and effective therapy compared with surgical aortic valve replacement (SAVR) in patients across all risk profiles using balloon-expandable valves (BEV) and self-expanding valves (SEV). Our aim was to compare safety and efficacy of BEV vs. SEV in high-risk patients undergoing TF-TAVR. Methods and results: We searched PubMed, EMBASE, Clinicaltrials.gov, Scopus, and Web of sciences for studies on patients with severe aortic stenosis undergoing TAVR. Primary outcome was 30-day all-cause mortality. Secondary outcomes defined by Valve Academic Research Consortium 2 (VARC-2) criteria were also examined. Six studies with 2,935 patients (1,439 to BEV and 1,496 to SEV) were included. BEV was associated with lower risk of all-cause mortality (2.2% vs. 4.5%; RR: 0.51; 95% CI: 0.31-0.82; p < 0.006) and cardiovascular mortality [(2.5% vs. 4.3%; RR: 0.54; 95% CI: 0.32-0.90; p = 0.01) at 30 days compared with SEV. Implantation of more than one valve per procedure (0.78% vs. 5.11%; RR: 0.15; 95% CI: 0.07-0.31; p < 0.00001), and moderate/severe AR/PVL (2.5% vs. 9.01%; RR: 0.3; 95% CI: 0.17-0.48); p < 0.00001) were also lower in the BEV arm. Conclusion: BEV TAVR is associated with reduced all-cause mortality (High level of GRADE evidence), cardiovascular mortality (very low level) at 30 days compared with SEV TAVR in high surgical risk patients. Data are necessary to determine if the difference in outcomes persists in longer-term and if the same effects are seen in lower-risk patients.

The new generation Watchman FLX device (Boston Scientific) was implanted in this technically and anatomically challenging LAA patient using multimodality fusion imaging. (Level of Difficulty: Advanced.).
RESUMO
BACKGROUND: Coronary intervention is routinely deferred in intermediate lesions with fractional flow reserve (FFR) ≥ 0.80. Patients with borderline FFR (0.80-0.85) who were initially deferred, have been shown to have higher risk of future interventions; however, the data is limited, and the long term prognosis in these patients remains unknown. We assessed the utility of adjunctive imaging modalities to determine the need for intervention in lesions with borderline FFR. METHODS: We retrospectively evaluated consecutive patients who underwent coronary angiography at Einstein Medical Center from January 2013 to April 2016. All patients with borderline FFR (0.80-0.85) were included. Patients were divided into Defer or Perform intervention groups based on additional available or procured clinical data. The Perform group was further stratified into intervention With or Without adjunctive imaging guidance (including intravascular ultrasound, optical coherence tomography, echocardiography, and exercise or pharmacologic stress test). Follow-up data was collected for all patients, which included future target lesion revascularization (TLR) and major adverse cardiac events (MACE; all-cause and cardiovascular mortality and acute coronary syndromes). RESULTS: A total of 196 patients were eligible. Median (IQR) FFR in Perform and Defer groups was 0.81 (0.8-0.83) and 0.84 (0.82-0.85) respectively. Median (IQR) follow up was 21 (13-29) and 25 (15-36) months respectively. Overall MACE rate in Perform group (n = 101) was 20.8% (n = 21) and Defer group (n = 95) was 15.8% (n = 15). The stratified MACE rate in Perform group With imaging guidance (n = 57) was 17.5% (n = 10) and Without imaging guidance (n = 44) was 25% (n = 11). Overall, the FFR only guided management (n = 196) led to MACE rate of 18.4% (n = 36); whereas, FFR With imaging guidance (n = 136) led to MACE rate of 16.2% (n = 22). The p values were non-significant in each of the above group comparisons due to relatively low numbers with trends as noted. CONCLUSIONS: Our study suggests that intervention of coronary lesions with borderline FFR under imaging guidance, although not significant, trends towards improved cardiovascular outcomes compared with intervention in this group without adjunctive imaging. These findings are merely speculative without achieving statistical significance in a small subset and need to be further validated in a large scale prospective study.

BACKGROUND: Refractory hypertension (RfHTN), a phenotype of antihypertensive treatment failure, is defined as uncontrolled automated office blood pressure (AOBP) ≥130/80 mm Hg and awake ambulatory blood pressure (ABP) ≥130/80 mm Hg on ≥5 antihypertensive medications, including chlorthalidone and a mineralocorticoid receptor antagonist. Previous studies suggest that RfHTN is attributable to heightened sympathetic tone. The current study tested whether reserpine, a potent sympatholytic agent, lowers blood pressure (BP) in patients with RfHTN. METHODS: Twenty-one out of 45 consecutive patients with suspected RfHTN were determined to be fully adherent with their antihypertensive regimen. Seven patients agreed to participate in the current clinical trial with reserpine and 6 patients completed the study. Other sympatholytic medications, such as clonidine or guanfacine, were tapered and discontinued before starting reserpine. Reserpine 0.1 mg daily was administered in an open-label fashion for 4 weeks. All patients were evaluated by AOBP and 24-hour ABP at baseline and after 4 weeks of treatment. RESULTS: Reserpine lowered mean systolic and diastolic AOBP by 29.3 ± 22.2 and 22.0 ± 15.8 mm Hg, respectively. Mean 24-hour systolic and diastolic ABPs were reduced by 21.8 ± 13.4 and 15.3 ± 9.6 mm Hg, mean awake systolic and diastolic ABPs by 23.8 ± 11.8 and 17.8 ± 9.2 mm Hg, and mean asleep systolic and diastolic ABPs by 21.5 ± 11.4 and 13.7 ± 6.4 mm Hg, respectively. CONCLUSIONS: Reserpine, a potent sympatholytic agent, lowers BP in patients whose BP remained uncontrolled on maximal antihypertensive therapy, lending support to the hypothesis that excess sympathetic output contributes importantly to the development of RfHTN.

Masked uncontrolled hypertension (MUCH) is defined as controlled automated office blood pressure (BP; AOBP <135/85 mm Hg) in-clinic in patients receiving antihypertensive medication(s) but uncontrolled BP out-of-clinic by 24-hour ambulatory BP monitoring (ABPM; awake ≥135/85 mm Hg). We hypothesized that MUCH patients have greater out-of-clinic sympathetic activity compared with true controlled hypertensives. Patients being treated for hypertension were prospectively recruited after 3 or more consecutive clinic visits. All patients were evaluated by in-clinic automated office BP, plasma catecholamines, and spot-urine/plasma metanephrines. In addition, out-of-clinic 24-hour ABPM, 24-hour urinary for catecholamines and metanephrines was done. Out of 237 patients recruited, 169 patients had controlled in-clinic BP of which 156 patients had completed ABPM. Seventy-four were true controlled hypertensives, that is controlled by clinic automated office BP and by out-of-clinic ABPM. The remaining 82 were controlled by clinic automated office BP, but uncontrolled during out-of-clinic ABPM, indicative of MUCH. After exclusion of 4 patients because of inadequate or lack of 24-hour urinary collections, 72 true controlled hypertensive and 80 MUCH patients were analyzed. MUCH patients had significantly higher out-of-clinic BP variability and lower heart rate variability compared with true controlled hypertensives, as well as higher levels of out-of-clinic urinary catecholamines and metanephrines levels consistent with higher out-of-clinic sympathetic activity. In contrast, there was no difference in in-clinic plasma catecholamines and spot-urine/plasma levels of metanephrines between the 2 groups, consistent with similar levels of sympathetic activity while in clinic. MUCH patients have evidence of heightened out-of-clinic sympathetic activity compared with true controlled hypertensives, which may contribute to the development of MUCH.

The treatment of ST-segment elevation myocardial infarction (STEMI) has advanced dramatically over the past 30 years since the introduction of reperfusion therapies, such that mechanical reperfusion with primary percutaneous coronary intervention is now the standard of care. With STEMI, as with other forms of acute coronary syndrome, stent deployment in culprit lesions is the dominant form of reperfusion in the developed world and is supported by contemporary guidelines. However, the precise timing of stenting and the extent to which both culprit and non-culprit lesions should be treated continue to be active areas of study. In this review, we revisit key data that support the use of mechanical reperfusion therapy in STEMI patients and explore the optimal timing for and extent of stent implantation in this complex patient group. We also review data surrounding the deleterious effects of untreated residual myocardial ischemia, the importance of complete revascularization, and the recent data exploring culprit-only versus multivessel stenting in the STEMI setting.

INTRODUCTION: The interwoven nitinol design of the Supera stent has been shown to have superior radial strength and fracture resistance resulting in higher patency rates at 6 and 12months. A detailed sub-analysis of SUPERB trial showed differences in patency based on stent conformation post deployment. We evaluated the patency of the stent within the SAKE study cohort based on stent deployment conformation. METHODS: We retrospectively evaluated the medical records of 63 patients (77 limbs) with Rutherford class 2-5 symptoms who received Supera stents in the femoro-popliteal artery from March 2010 through May 2011 as part of the SAKE study. These patients were followed for patency and the need for re-intervention over a mean follow up of 15months. Compression or Elongation was defined as follows based on previous sub-analyses: Moderate Compression (-40 to -21%); Minimal Compression (-20 to -11%); Nominal (-10 to 10%); Minimal Elongation (11 to 20%); Moderate Elongation (21 to 40%); and Severe Elongation (>40%). Significance was determined using Chi X2 test. RESULTS: The best patency rates (85.2% primary patency and 92.6% assisted primary patency) and lowest re-intervention rates (14.8%) were achieved with stent compression, followed by nominal deployment or minimal elongation, and worst outcomes (64.7% primary patency; 82.3% assisted primary patency; and 35.3% re-intervention) with stent elongation to moderate or severe degree. CONCLUSIONS: Patency rates and re-intervention rates are variable based on deployment characteristics of the Supera stent. Best outcomes are achieved with compression of the stent during deployment.

Chronic total occlusions (CTO) are common in patients with symptomatic peripheral arterial disease. Endovascular CTO intervention remains a challenging endeavor for interventionalists, but is being increasingly considered as a plausible alternative to surgical revascularization, even for complex CTO lesions. We review common endovascular techniques using antegrade, retrograde and transcollateral approaches in femoropopliteal CTO intervention. In addition, we review the current literature on the utility, efficacy, and safety of novel crossing and re-entry devices in femoropopliteal CTO interventions.

Coronary chronic total occlusion (CTO) intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI) attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i.e., using fractional flow reserve). In this review we present the current literature describing the utility and efficacy of these adjunctive modalities in CTO intervention.

Systolic blood pressure (SBP) is an important predictor of cardiovascular disease (CVD) outcomes. Lowering SBP has been shown to reduce CVD morbidity and mortality, but the optimal SBP target continues to be a topic of intense debate. The Systolic Blood Pressure Intervention Trial (SPRINT) reported a significantly lower risk for CVD outcomes and all-cause mortality by targeting SBP <120 mmHg compared with <140 mmHg in a population of hypertensive persons at high CV risk. In this review, we discuss the strengths, limitations, and generalizability of SPRINT findings to other hypertensive populations that were excluded from the trial, including those with diabetes or prior stroke, <50 years old, and at lower CVD risk. We will focus on the implications of SPRINT findings for appropriate BP targets in high-risk groups of hypertensive persons, including the elderly and those with chronic kidney disease (CKD). We will also address the cost-effectiveness of intensive BP treatment as implemented in SPRINT and the implications of SPRINT for health care policy and future BP guidelines.

We evaluated the prevalence of major and minor electrocardiographic (ECG) abnormalities based on blood pressure (BP) control and hypertension (HTN) treatment resistance. We analyzed data from the Reasons for Geographic and Racial Differences in Stroke study of 20,932 participants who were divided into presence of major (n = 3782), only minor (n = 8944), or no (n = 8206) ECG abnormalities. The cohort was stratified into normotension (n = 3373), pre-HTN (n = 4142), controlled HTN (n = 8619), uncontrolled HTN (n = 3544), controlled apparent treatment-resistant HTN (aTRH, n = 400), and uncontrolled aTRH (n = 854) groups, and the prevalence ratios (PRs) of major and minor ECG abnormalities were assessed separately for each BP group. The full multivariable adjustment included demographics, risk factors, and HTN duration. Compared with normotension, the PRs of major ECG abnormalities for pre-HTN, controlled HTN, uncontrolled HTN, controlled aTRH, and uncontrolled aTRH groups were 1.01 (0.90-1.14), 1.30 (1.16-1.45), 1.37 (1.23-1.54), 1.42 (1.22-1.64), and 1.44 (1.26-1.65), respectively (P < .001), whereas the PRs of minor ECG abnormalities among each of the above BP groups were similar. Detection of major ECG abnormalities among hypertensive persons with poor control and treatment resistance may help improve their cardiovascular risk stratification and early intervention.

The association of atrial fibrillation (AF) with the severity and control of hypertension (HTN) remains unclear. We analyzed data from the national biracial cohort of REasons for Geographic And Racial Differences in Stroke study. The AF prevalence ratios were estimated and full multivariable adjustment included demographics, risk factors, medication adherence, HTN duration, and antihypertensive medication classes. Of the 30,018 study participants (8.6% with AF), 4386 had normotension (4.3% with AF), 5916 had prehypertension (4.3 with AF%), 12,294 had controlled HTN (11.2% with AF), 5587 had uncontrolled HTN (8.1% with AF), 547 had controlled apparent treatment-resistant hypertension (aTRH) (19.2% with AF), and 1288 had uncontrolled aTRH (15.5% with AF). Compared with normotension, the AF prevalence ratios for prehypertension, controlled HTN, uncontrolled HTN, controlled aTRH, and uncontrolled aTRH groups in fully adjusted model were 1.01 (95% confidence interval: 0.84, 1.21), 1.42 (1.18, 1.71), 1.37 (1.14, 1.65), 1.17 (0.86, 1.58), and 1.42 (1.10, 1.84), respectively (P < .001). The prevalence of AF was similar among persons with HTN regardless of blood pressure level and antihypertensive treatment resistance.

The prevalence of pseudoresistant hypertension (HTN) due to inaccurate BP measurement remains unknown. Triage BP measurements and measurements obtained at the same clinic visit by trained physicians were compared in consecutive adult patients referred for uncontrolled resistant HTN (RHTN). Triage BP measurements were taken by the clinic staff during normal intake procedures. BP measurements were obtained by trained physicians using the BpTRU (VSM Med Tech Ltd. Coquitlam, Canada) device. The prevalence of uncontrolled RHTN and differences in BP measurements were compared. Of 130 patients with uncontrolled RHTN, 33.1% (n = 43) were falsely identified as having uncontrolled RHTN based on triage BP measurements. The median (inter-quartile range) of differences in systolic BP between pseudoresistant and true resistant groups were 23 (17-33) mm Hg and 13 (6-21) mm Hg, respectively (P = .0001). The median (inter-quartile range) of differences in diastolic BP between the two groups were 12 (7-18) mm Hg and 8 (4-11) mm Hg, respectively (P = .001). Triage BP technique overestimated the prevalence of uncontrolled RHTN in approximately 33% of the patients emphasizing the importance of obtaining accurate BP measurements.

Pulse pressure (PP), estimated from the peripheral blood pressure measurements, has been linked with adverse cardiovascular events. But, the association of PP and coronary artery disease is not well studied. There is a lack of data on the association of invasively measured aortic PP and cardiovascular risk factors and severity of coronary atherosclerosis. We determined the predictive factors of aortic PP during cardiac catheterization. Electronic medical records from 2010 to 2013 were retrospectively reviewed. A total of 368 patients were eligible. The data on demographics, cardiovascular risk factors, coronary lesion characteristics, and medication use was collected. On multivariable regression analysis, aging (ß = 0.34, p = 0.001, 95% confidence interval [CI] 0.14-0.53) and prior aspirin use (ß = 5.09, p = 0.015, 95% CI 0.99-9.18) were associated with higher aortic PP. Increasing estimated glomerular filtration rate (ß = - 0.52, p = 0.040, 95% CI -0.90 to -0.23) was associated with lower aortic PP. Severity and complexity of coronary lesions, SYNTAX score, and number of obstructed vessels were not associated with aortic PP. Aging, prior aspirin use, and declining renal function were associated with an increase in aortic PP. Aortic PP may not predict the severity and complexity of coronary atherosclerosis. Therefore, the risk of adverse cardiovascular events associated with an elevated aortic PP may not be mediated by the severity of coronary atherosclerosis.
RESUMO
The peak troponin level has been associated with cardiovascular (CV) mortality and adverse CV events. The association of peak troponin with CV risk factors and severity and complexity of coronary artery disease remains unknown. We assessed the predictors of peak troponin in patients with acute coronary syndrome (ACS). This study aims to determine the predictors of peak troponin in ACS. Cardiac catheterization (CC) reports and electronic medical records from 2010 to 2013 were retrospectively reviewed. A total of 219 patients were eligible for the study. All major CV risk factors, comorbidities, laboratory data, CC indications, and coronary lesion characteristics were included. Univariate and multivariate regression analyses were done. On multivariate linear regression analysis, ST-elevation myocardial infarction (p = 0.001, ß = 65.16) and increasing synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) score (p = 0.002, ß = 1.15) were associated with higher peak troponin. The Pearson correlation between SYNTAX score and peak troponin was r = 0.257, p = 0.001. History of daily aspirin use was associated with lower peak troponin (p = 0.002, ß = -24.32). Prior statin use (p = 0.321, ß = -8.98) and the presence of CV risk factors were not associated with peak troponin. Coronary artery disease severity and complexity, urgency of CC, and prior aspirin use are associated with peak troponin levels in ACS. Our findings may help predict patient population with ACS who would be at a greater risk for short- and long-term CV morbidity and mortality due to elevated peak troponin.
RESUMO
AIM: We assessed the association of aortic valve sclerosis (AVS) with atherosclerotic risk factors and severity and complexity of coronary artery disease (CAD). METHODS: In this retrospective study, a total of 482 eligible patients were divided into 2 groups: AVS present and AVS absent. All major cardiovascular risk factors and coronary lesion characteristics were included. RESULTS: Age was the only independent predictor of AVS. AVS was not independently associated with the number of obstructive vessels, degree of lesion obstruction and SYNTAX score. CONCLUSION: AVS is probably a benign marker of age-related degenerative changes in the heart independent of the severity and complexity of CAD.

REasons for Geographic and Racial Differences in Stroke (REGARDS) is a longitudinal study supported by the National Institutes of Health to determine the disparities in stroke-related mortality across USA. REGARDS has published a body of work designed to understand the disparities in prevalence, awareness, treatment, and control of coronary heart disease (CHD) and its risk factors in a biracial national cohort. REGARDS has focused on racial and geographical disparities in the quality and access to health care, the influence of lack of medical insurance, and has attempted to contrast current guidelines in lipid lowering for secondary prevention in a nationwide cohort. It has described CHD risk from nontraditional risk factors such as chronic kidney disease, atrial fibrillation, and inflammation (i.e., high-sensitivity C-reactive protein) and has also assessed the role of depression, psychosocial, environmental, and lifestyle factors in CHD risk with emphasis on risk factor modification and ideal lifestyle factors. REGARDS has examined the utility of various methodologies, e.g., the process of medical record adjudication, proxy-based cause of death, and use of claim-based algorithms to determine CHD risk. Some valuable insight into less well-studied concepts such as the reliability of current troponin assays to identify "microsize infarcts," caregiving stress, and CHD, heart failure, and cognitive decline have also emerged. In this review, we discuss some of the most important findings from REGARDS in the context of the existing literature in an effort to identify gaps and directions for further research.

The association of cardiovascular risk factors and complexity and severity of coronary artery disease with contrast volume (CV) remains unknown. We assessed the predictive factors of CV use during elective and emergent cardiac catheterization (CC). Electronic medical records from 2010 to 2013 were retrospectively reviewed. A total of 708 patients were eligible. On multivariable regression analysis, the presence of obstructed coronary arteries was associated with CV (P = .01, ß = -14.17), with greater CV used in patients with single or double vessel disease compared to those with triple vessel disease. The presence of lesions with >70% stenosis in major epicardial arteries (P = .019, ß = 24.39) and ST-segment elevation myocardial infarction (P = .001, ß = 36.14) was associated with increased CV use. Elevated B-type natriuretic peptide (P = .036, ß = -17.23) and increase in Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score (P = .024, ß = -29.06) were associated with decreased CV use. These aforementioned associations were attenuated after adjusting for percutaneous coronary intervention. Our findings may help predict patient populations who could be exposed to increased CV during CC, thereby possibly increasing their risk of contrast-induced nephropathy.
