Background Microvascular dysfunction might be a major determinant of clinical deterioration and outcome in patients with hypertrophic cardiomyopathy (HCM). However, long‐term prognostic value of transthoracic Doppler echocardiography (TDE) coronary flow velocity reserve (CFVR) on clinical outcome is uncertain in HCM patients. Therefore, the aim of our study was to assess long‐term prognostic value of CFVR on clinical outcome in HCM population. Methods and Results We prospectively included 150 HCM patients (82 women; mean age 48±15 years). Patients’ clinical characteristics, echocardiographic and CFVR findings (both for left anterior descending [LAD] and posterior descending artery [PD]), were assessed in all patients. The primary outcome was a composite of: HCM related death, heart failure requiring hospitalization, sustained ventricular tachycardia and ischemic stroke. Patients were stratified into 2 subgroups depending on CFVR LAD value: Group 1 (CFVR LAD>2, [n=87]) and Group 2 (CFVR LAD≤2, [n=63]). During a median follow‐up of 88 months, 41/150 (27.3%) patients had adverse cardiac events. In Group 1, there were 8/87 (9.2%), whereas in Group 2 there were 33/63 (52.4%, P <0.001 vs. Group 1) adverse cardiac events. By Kaplan‐Meier analysis, patients with preserved CFVR LAD had significantly higher cumulative event‐free survival rate compared to patients with impaired CFVR LAD (96.4% and 90.9% versus 66.9% and 40.0%, at 5 and 8 years, respectively: log‐rank 37.2, P <0.001). Multivariable analysis identified only CFVR LAD≤2 as an independent predictor for adverse cardiac outcome (HR 6.54; 95% CI 2.83–16.30, P <0.001), while CFVR PD was not significantly associated with outcome. Conclusions In patients with HCM, impaired CFVR LAD (≤2) is a strong, independent predictor of adverse cardiac outcome. When the aim of testing is HCM risk stratification and CFVR LAD data are available, the evaluation of CFVR PD is redundant.

Abstract Aims A comparative analysis and evaluate the effectiveness and prognostic value of optical coherence tomography (OCT) and fractional flow reserve (FFR) guiding measurement in patients with stenosis of the terminal part of the left main coronary artery (LMCA). Methods 222 patients were selected in the study. Inclusion criteria: true bifurcation stenosis of the LMCA according to quantitative coronary angiography (QCA) and classification by A. Medina. Criteria for determining the hemodynamic significance of stenosis: according OCT - minimal lumen area (MLA) in the terminal part of LMCA &lt;6 mm2; according FFR guiding – &lt;0.8 (in LCx or LAD or both). Patients, who have not been diagnosed hemodynamically significant stenosis, were further subjected to the dynamic observation. All received optimal medical therapy. The study continued to participate patients whose compliance to receive drugs was not lower than 80%. Primary endpoints: frequency of MACE (death, myocardial infarction, revascularizations). The follow-up were 12, 24, 36 months. Results The OCT was performed in 110 patients and FFR guiding measurement – in 112 patients. According to the OCT, were hemodynamically significant stenoses are determined in 36 (32.7%) patients and after FFR-guiding measurement – in 32 (28.6%) of patients (χ2=2.184 p&gt;0.05). Patients without hemodynamically significant stenoses distributed into 2 groups: group 1 (n=74) – according to the OCT and group 2 (n=80) – according to the FFR. The long-term results were monitored in all patients. The frequency of myocardial infarction in group 1 were 1.4% and in group 2 – 7.5% (p&lt;0.05).The frequency of revascularization in group 1 were 5.4% and in group 2 – 15% (p&lt;0.05). The total frequency of major cardiac events were 6.75% in group I and 22.5% in group II (χ2=6.435; p&lt;0.001). The survival without major cardiac events (Kaplan-Maier analysis) were significantly differ between the groups, of 93.25% in group 1 and 77.5% – in group 2 (χ2=7.162 p&lt;0.001). Conclusions The effectiveness of the OCT imaging and the FFR-guiding measurement in determining the hemodynamic significance of the bifurcation stenosis of the LMCA, not different. However, in the long term period, patients with insignificant stenosis identified by the FFR, have a worse prognosis and are distinguished by a major cardiac events, compared with the OCT, which does not allow us to recommend the FFR method as the main one for determining the hemodynamic significance of LMCA.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Since mitral regurgitation (MR) is a very common finding in patients with hypertrophic cardiomyopathy (HCM), the evaluation of the mitral valve anatomy and the degree of MR is of utmost importance in this population. However, data regarding the prognostic value of different degrees of MR in HCM remains scarce. Purpose The aim of this study was to determine whether the presence of a higher degree of MR affects: 1) long term prognosis; 2) clinical and echocardiographic presentation of HCM patients. Material and Methods We included prospectively 102 patients, diagnosed with primary asymmetric HCM. The degree of MR was determined echocardiographicaly according to current recommendations of the American Association of Echocardiography. According to the MR severity, patients were divided into 2 groups: Group 1 (n = 52) with no/trace or mild MR and Group 2 with moderate or moderate to severe MR. All patients had clinical and echocardiographic examination, 24-hour Holter ECG and NT pro BNP analysis performed. The primary outcome was a composite of: 1) HCM related death or sudden death; 2) hospitalization due to acute heart failure; 3) sustained ventricular tachycardia; 4) ischemic stroke. Results Patients with higher MR degree had more frequent chest pain (p = 0.039), syncope (p = 0.041) and NYHA II functional class (p &lt; 0.001). Group 2 patients had mostly obstructive form of HCM (p &lt; 0.001) with more frequent presence of previous atrial fibrillation (AF) (p = 0.032), as well as the new onset of AF (p = 0.014) compared to patients in Group 1. Patients with higher MR degree had significantly more SAM (p &lt; 0.001) resulting in a more frequent eccentric MR jet (p &lt; 0.001), along with calcified mitral annulus (p = 0.007), enlarged left atrial volume index (p &lt; 0.001), and elevated right ventricular pressure (p = 0.001). As a result of higher MR grade, Group 2 had higher E/e" values (p &lt; 0.001), elevated LV filling pressure (lateral E/e’ &gt;10), as well as higher levels of NT pro BNP (p = 0.001). By Kaplan-Meier analysis we demonstrated that the event free survival rate during follow up of median 75 (IQR 48-103) months was significantly higher in Group 1 compared to the Group 2 (79% vs. 46%, p &lt; 0.001), Figure 1. After adjustment for relevant confounders, moderate/moderate to severe MR remained as an independent predictor of adverse outcome (hazard ratio 2.58, 95% CI: 1.08-6.13, p &lt; 0.001). Conclusion Presence of moderate, or moderate to severe MR was associated with poor long-term outcome of HCM patients. These results indicate the importance of an adequate MR assessment and detailed evaluation of the mitral valve anatomy in the prediction of complications and adequate treatment of patients with HCM.

Abstract Background Inflammatory status pre-percutaneous coronary intervention (PCI) and post-PCI has been reported not only associated with poor prognosis, but also to impair renal function. Statins reduce cardiovascular events by lowering lipids and have anti-inflammatory impacts, but residual inflammatory risk (RIR) exists. It remains unclear that the synergistic effect of RIR and chronic kidney disease (CKD) on long-term clinical outcome in stable coronary artery disease (CAD) patients undergoing PCI in statin era. Aim The aim of this study was to investigate the long-term combined impact of RIR evaluating hs-CRP at follow-up and CKD among stable CAD patients undergoing PCI in statin era. Methods This is a single-center, observational, retrospective cohort study assessing consecutive 2,984 stable CAD patients who underwent first PCI from 2000 to 2016. We analyzed 2,087 patients for whom hs-CRP at follow-up (6–9 months later) was available. High residual inflammatory risk was defined as hs-CRP &gt;0.6 mg/L according to the median value at follow up. Patients were assigned to four groups as Group1 (high RIR and CKD), Group2 (low RIR and CKD), Group3 (high RIR and non-CKD) or Group4 (low RIR and non-CKD). We evaluated all-cause death and major adverse cardiac events (MACE), defined as a composite of cardiovascular (CV) death, non-fatal myocardial infarction (MI) and non-fatal stroke. Results Of patients (83% men; mean age 67 years), there were 299 (14.3%) patients in group 1, 201 (9.6%) patients in group 2, 754 (36.1%) patients in group 3, and 833 (39.9%) patients in group 4. The median follow-up period was 5.2 years (IQR, 1.9–9.9 years). In total, 189 (frequency, 16.1%) cases of all-cause death and 128 (11.2%) MACE were identified during follow-up, including 53 (4.6%) CV deaths, 27 (2.4%) MIs and 52 (4.8%) strokes. The rate of all-cause death and MACE in group 1 was significantly higher than other groups (p&lt;0.001, respectively). There was a stepwise increase in the incidence rates of all-cause death and MACE. After adjustment for important covariates, the presence of high RIR and/or CKD were independently associated with higher incidence of MACE and higher all-cause mortality. (shown on figure). Conclusion The presence of both high RIR and CKD conferred a synergistic adverse effect on the risk for long-term adverse cardiac events in patients undergoing PCI.

Abstract Objective The main objective of this article is to study the usefulness of coronary sinus filling time (CSFT) as a predictor of coronary microvascular obstruction (CMVO) and future cardiovascular (CV) events after percutaneous coronary intervention (PCI) for left anterior descending (LAD) in stable coronary artery disease patients. Materials and Methods We analyzed 50 patients with stable angina who underwent elective PCI for single LAD significant stenosis. After stent deployment, coronary sinus was visualized in left anterior oblique 40 degree cranial 30 degree views, CSFT, and corrected thrombolysis in myocardial infarction frame count (cTFC) calculated from frame count. Post-procedure electrocardiographic changes noted and cardiac biomarker creatine phosphokinase and creatine phosphokinase-myocardial band levels estimated, and follow-up was done for 6 months. Patients classified into two groups: Group 1 with major adverse cardiac events (MACE) and Group 2 (without MACE). CSFT and cTFC measurements were compared among the two groups. Results Out of 50 patients who were recruited in the study, Group 1 comprises 20 patients, and Group 2 comprises 30 patients. Among the Group 1, 40% were females, while in Group 2, they were 16%. Group 1 showed high CSFT values compared to Group 2, and such are post-procedure ST, T changes (90% in Group 1, 20% in Group 2), cardiac biomarkers elevation (80% in Group 1, 23.3% in Group 2). At 6 months follow-up ejection fraction was lower in Group 1 (31.8 ± 6.4%) compared with Group 2 (58.8 ± 5.8%) at p < 0.0001, and angina (85%) versus (20%). Mean CSFT was significantly more in Group 1 (5.77 ±0.75s) compared with Group 2 (4.61 ± 0.55s) at p < 0.0001. With respect to cTFC, no significant differences were seen between the two groups (p < 0.5628). Receiver operating characteristic curve analysis showed CSFT of > 5.2s was the best cutoff value to differentiate the two groups. Conclusion CSFT significantly prolonged in patients with adverse cardiac events, and it may be used as a simple and quantitative predictor of CMVO and future CV events after elective PCI.

Background Preoperative N-terminal pro-BNP (NT-proBNP) is independently associated with adverse cardiac outcome but does not anticipate the dynamic consequences of anesthesia and surgery. The authors hypothesized that a single postoperative NT-proBNP level provides additional prognostic information for in-hospital and late cardiac events. Methods Two hundred eighteen patients scheduled to undergo vascular surgery were enrolled and followed up for 24-30 months. Logistic regression and Cox proportional hazards model were performed to evaluate predictors of in-hospital and long-term cardiac outcome. The optimal discriminatory level of preoperative and postoperative NT-proBNP was determined by receiver operating characteristic analysis. Results During a median follow-up of 826 days, 44 patients (20%) experienced 51 cardiac events. Perioperatively, median NT-proBNP increased from 215 to 557 pg/ml (interquartile range, 83/457 to 221/1178 pg/ml; P&lt;0.001). The optimum discriminate threshold for preoperative and postoperative NT-proBNP was 280 pg/ml (95% confidence interval, 123-400) and 860 pg/ml (95% confidence interval, 556-1,054), respectively. Adjusted for age, previous myocardial infarction, preoperative fibrinogen, creatinine, high-sensitivity C-reactive protein, type, duration, and surgical complications, only postoperative NT-proBNP remained significantly associated with in-hospital (adjusted hazard ratio, 19.8; 95% confidence interval, 3.4-115) and long-term cardiac outcome (adjusted hazard ratio, 4.88; 95% confidence interval, 2.43-9.81). Conclusion A single postoperative NT-proBNP determination provides important additional prognostic information to preoperative levels and may support therapeutic decisions to prevent subsequent structural myocardial damage.

Background The aim of this study performed in patients undergoing major orthopedic surgery was to assess the impact of changes in practice on both the incidence of postoperative myocardial ischemia (PMI) detected by serial measurements of troponin Ic and long-term cardiac outcome. Methods During a 3-yr period, troponin Ic was measured on the first 3 days after major orthopedic surgery in a multidisciplinary hospital. After 16 months of study, postoperative care was improved. Cardiac death, myocardial infarction, and cardiac failure were considered major adverse cardiac events and were recorded during the hospital stay and the first postoperative year. The incidences of PMI and major adverse cardiac events were used as result indicators for quality of care and compared before (P1) and after (P2) quality enhancement. Results Three hundred seventy-eight surgical procedures were included (P1, 123; P2, 255). Incidences of PMI and major adverse cardiac events were 8.9 versus 3.9% (P=0.04) and 8.1 versus 1.9% (P=0.004) for P1 and P2, respectively. Using a multivariate Cox regression analysis adjusted for baseline data, independent factors associated with the occurrence of a major adverse cardiac event were phase P1 (hazard ratio=4.5; 97.8% confidence interval [CI], 1.1-17.4) and PMI (Hazard ratio=6.4; 97.8% CI, 1.6-26.4). Conclusions Our postoperative care policy after major orthopedic surgery strongly correlated with both short-term cardiac outcome (i.e., PMI with troponin Ic release) and long-term cardiac outcome. Thus, in a given surgical population, variation of incidence of troponin Ic elevations could be used as a result indicator for postoperative care policy.

Computed tomographic coronary angiography (CTCA) has prognostic value for early major adverse cardiac events (MACEs) after liver transplantation. However, the association between CTCA and long-term MACEs in liver transplant (LT) recipients remains unknown. We evaluated the association between CTCA and long-term MACEs within 5 years after living donor liver transplantation (LDLT). A total of 628 LDLT recipients who underwent CTCA were analyzed between 2010 and 2012. MACEs were investigated within 5 years after LDLT. The factors associated with long-term MACEs in transplant recipients were evaluated. Only 48 (7.6%) patients developed MACEs. In the Fine and Gray competing risk regression, a coronary artery calcium score (CACS) of >400 combined with obstructive coronary artery disease (CAD) (subdistribution hazard ratio: 5.01, 95% confidence interval: 2.37–10.58, p < 0.001), age (1.05, 1.01–1.10, p = 0.018), diabetes mellitus (2.43, 1.37–4.29, p = 0.002), dyslipidemia (2.45, 1.23–4.70, p = 0.023), and creatinine (1.19, 1.08–1.30, p < 0.001) were independently associated with long-term MACEs. CACS (>400) combined with obstructive CAD may be associated with MACEs within 5 years after LDLT, suggesting the importance of preoperative noninvasive CTCA in LT recipients. The evaluation of coronary artery stenosis on CTCA combined with CACS may have a prognostic value for long-term MACEs in LT recipients.
