Background. Wellens syndrome (WS) has been described as a clinical and electrocardiographic (ECG) complex that identifies a subset of patients with unstable angina (UA) at an impending risk of myocardial infarction (MI) and death in studies published almost 4 decades ago, before the wide use of cardiac biomarkers such as troponins. The mid and long term outcomes of patients with Wellens syndrome have never been compared with a contemporary cohort of patients with non-ST elevation acute coronary syndromes (NSTEACS). Objectives. The primary endpoints of our study were the rate of cardiovascular rehospitalizations, the rate of ischaemic reccurences, the rate of subsequent or reccurent revascularization and the rate of mortality at six months from the index event. Materials and methods. We performed a prospective analysis of 64 consecutive patients with WS who underwent coronary angiography and we compared them with an age and sex matched cohort of patients with NSTEACS who underwent coronary angiography. The study took place at Bagsadar-Arseni Emergency Clinical Hospital and included a total of 127 patients recruited within 2 years (from January 2018 until December 2019), who were followed for a period of 6 months. Results. Within 6 months of follow-up, patients in the control group had a significantly higher rate of cardiovascular rehospitalizations (41.9% vs. 21.9%, p = 0.016), although the rate of ischaemic recurrences was similar between the 2 groups. Other interventional end-points, such as subsequent interventional revascularization, repeat interventional revascularization and repeat target vessel revascularization (TVR) were comparable between the 2 groups at 6 months follow-up. There was no significantly difference with respect to global mortality (6.3% in WS group vs. 7.9% in the control group, p = 0.74). Discussions. To our knowledge, this is the first prospective study with mid term follow up that compared a consecutive cohort of patients with WS who underwent coronary angiography with an age and sex matched cohort of patients with NSTEACS. Patients with WS had similar event rates with respect to ischaemic recurrences, subsequent or repeat interventional revascularization and repeat target vessel revascularization (TVR) and mortality rate at 6 months, although significantly more patients in WS group were considered at low risk. Conclusions. Wellens sign is frequently overlooked in the emergency department and risk assessment based on risk scores is frequently misleading. Prompt recognition of subtle ECG ischaemic changes, such as WS, in patients with chest pain is crucial, as it reflects a large area of myocardium at risk and identifies a subgroup of patients who can benefit from early invasive management.

(1) Background: Knowledge about predictors for the long-time patency of recanalized chronic total coronary occlusions (CTOs) is limited. Evidence from invasive follow-up in the absence of acute coronary syndrome (routine surveillance coronary angiography) is scarce. (2) Methods: In a monocentric-retrospective analysis, we obtained baseline as well as periprocedural data of patients undergoing routine invasive follow-up. We defined target vessel failure (TVF) as a combined primary endpoint, consisting of re-occlusion, restenosis, and target vessel revascularization (TVR). (3) Results: We included 93 consecutive patients (15.1% female) from October 2013 to May 2018. After a follow-up period of 206 ± 129 days (median 185 (IQR 127–237)), re-occlusion had occurred in 7.5%, restenosis in 11.8%, and TVR in 5.4%; the cumulative incidence of TVF was 15.1%. Reduced TIMI-flow immediately after recanalization (OR for TVR: 11.0 (95% CI: 2.7–45.5), p = 0.001) as well as female gender (OR for TVR: 11.0 (95% CI: 2.1–58.5), p = 0.005) were found to be predictive for pathological angiographic findings at follow-up. Furthermore, higher blood values of high-sensitive troponin after successful revascularization were associated with all endpoints. Interestingly, neither the J-CTO score nor the presence of symptoms at the follow-up visit could be correlated to adverse angiographic results. (4) Conclusions: In this medium-sized cohort of patients with surveillance coronary angiography, we were able to identify reduced TIMI flow and female gender as the strongest predictors for future TVF.

Introduction: Drug-eluting Stent(DESs) have demonstrated improved patency and freedom from target lesion revascularization compared with Bare-Metal stents or Percutaneous Transluminal Angioplasty(PTA); however, the effect on clinical outcome parameters, such as limb salvage and wound healing, remains unidentified. We present a direct comparison of clinical outcomes in patients who underwent DES vs PTA. Methods: We collected data of patients who underwent infra-popliteal arterial interventions at our institution. Clinical end points analyzed were all cause mortality, target vessel revascularization, primary vessel patency, and target limb major and minor amputations. Differences between two groups were analyzed by chi square for categorical variables and t test for continuous variables. Statistical significance was considered for P values less than .05 in a 2-sided test. Results: Total of 83 cases, n=42 in DES group and n=41 in PTA group were analyzed. Mean age was 71.6 years (range 49-95). Out of the total 83 patients in the study 45 had a history of diabetes (54%) and 51 (61%) were current /past smokers. Average follow up period of 14 months for both the groups. Primary vessel patency was defined as absence of ≥50% restenosis on follow up. During the follow up period vessel patency in DES group [69% (n=29/42)] was significantly higher as compared to 36% (15/41) in PTA group (P=0.04, odds ratio 3.867, 95% Confidence interval: 1.5 - 9.6). Target vessel revascularization in DES group was 24% (10/42) as compared to 32% (13/28) in PTA group (P=0.47, odds ratio 0.67, 95% confidence interval: 0.26 - 1.77). Target limb amputation was 10% (4/42) in DES group as compared to 24% (10/41) in PTA group (P = 0.085), odds ratio 0.33, 95% confidence interval: 0.09 - 1.14). All cause mortality in both the groups were at 10%, 4/42 in DES group and 4/41 in PTA group (P=1, odds ratio 0.97, 95% confidence interval: 0.23 - 4.19). Conclusion: To conclude primary vessel patency was superior in DES group as compared to PTA group. Target limb amputation rates were higher in PTA group but not statistically significant. Target vessel revascularization and all cause mortality were similar in both the groups. Thus primary treatment with DES should be considered in patients with infra-popliteal PAD.

Abstract The study aimed to investigate the impact of angiographic and clinical outcomes of the drug-coated balloon (DCB)-only treatment for de novo coronary chronic total occlusion (CTO). One hundred one vessels with de novo CTO lesions dilated by balloon angioplasty with thrombolysis in myocardial infarction (TIMI) flow-grade 3 were assigned. Among them, we analyzed 93-vessel treated using DCB-only treatment. The primary endpoint was major adverse cardiac events (MACE), a composite of cardiac death, non-fatal myocardial infarction (MI), target vessel revascularization (TVR), and target vessel thrombosis. The secondary endpoint was late lumen loss (LLL) on follow-up coronary angiography. All 84-patient were followed up clinically, and 67-vessel underwent scheduled coronary angiography after 6-month. There were no procedural complications, and three vessels required bailout-stenting. MACE occurred in 14 patients, including 2 cardiac deaths, 3 non-fatal MIs, and 11 TVRs. There was no target vessel thrombosis. The mean LLL was 0.03 ± 0.53mm. Binary restenosis occurred in 10 and re-occlusion in 2 vessels. The results from a 2-year follow-up with DCB-only treatment are encouraging, with a low rate of hard endpoints and acceptable MACE rates. It may offer an alternative to the implantation of a drug-eluting stent if the CTO lesions have TIMI flow-grade 3 after pre-dilation.

Introduction: To evaluate the efficacy/safety profile of the Abluminus DES+ over 2-years follow-up in the "real-world" scenario in diabetics as compared to non-diabetics. Methods: In prospective, all-comers, open-label registry conducted at 31 sites, patients were analyzed for 1 & 2-year outcomes with the primary endpoint defined as 3P-MACE of CV death, target vessel related myocardial infarction (TV-MI), ischemia-driven target lesion revascularization (TLR)/target vessel revascularization (TVR) apart from Stent thrombosis (ST). Results: Of 2500 patients of PCI with 3286 Abluminus-DES+, 1641 (65.64%) were non-diabetics while859 (34.36%) were diabetics. The 3-P MACE for the cohort at 1 & 2 years were 2.9%, and 3.16%; TLR/TVR - 1.4% at both the intervals for 2493 patients at 2 yrs. follow-up. TV-MI & ST were 0.36% and0.56% at 1st and 2nd year respectively. The 3P-MACE was lower in non-diabetics at 1 & 2 years (2.3%vs 4.2%; 2.4% vs 4.7% respectively). For components of MACE, CV mortality (0.9 vs 1.9% at 1 yr ; 1.0vs 2.1% at 2 years) was significant (P < 0.05) while TLR (1.1 vs 1.9% at 1 yr. & 1.1 vs 2.1% at 2 yrs.) and TV-MI (0.9 vs 1.9% at 1 yr. & 1 vs 2.1% at 2 years) were similar for diabetics and non-diabetics so was ST (P > 0.05). Conclusion: Abluminus-DES+ showed excellent 2-year safety and efficacy with low 3-P MACE which was higher in diabetics driven by higher CV death but similar TLR, TV-MI and ST.

SummaryThe effect of preprocedural fibrinogen levels on in-stent restenosis is largely unknown. The –455 G/A polymorphism of the fibrinogen β-gene is associated with baseline plasma level or acute phase increase of fibrinogen. Therefore, we hypothesized that there is a relationship between this polymorphism and pre-procedural fibrinogen level and clinical restenosis at follow-up among patients with coronary stent placement. The GENetic DEterminants of Restenosis (GENDER) project is a multicenter follow-up study that enrolled 3,146 consecutive patients after successful percutaneous coronary intervention. A coronary stent was placed in 2,309 patients. Of these, 2,257 (97.7%) patients were successfully genotyped for the –455G/A polymorphism. Plasma fibrinogen levels were measured at baseline in a subpopulation of 623 stented patients with the von Clauss method and patients were grouped into tertiles according to fibrinogen levels. Primary endpoint was target vessel revascularization (TVR); secondary combined endpoint was defined as death presumably from cardiac causes, MI not attributable to another coronary artery than the target vessel, and TVR. No association was observed between the –455G/A polymorphism and TVR or combined endpoint (p=0.99, p=0.97, respectively). Multivariate regression analysis revealed that the risk of TVR and combined endpoint was not higher for patients in the highest tertile for fibrinogen versus the lowest tertile (RR=0.60, 95% CI: 0.26–1.37 for TVR, RR=0.64, 95% CI: 0.29–1.44 for combined endpoint). In conclusion, the presence of –455G/A polymorphism in the fibrinogen β-gene and preprocedural fibrinogen level is not associated with an increased risk of TVR or combined endpoint in a patient population with coronary stent placement. Therefore, these parameters are not worthwhile for stratifying patients at risk for restenosis prestenting.

Background: It is unclear whether the routine follow up (FU) coronary angiography (CAG) regardless of patient’s symptoms after successful percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) in patients (pts) with dyslipidemia is beneficial or not. Methods: The study population consisted of 554 consecutive dyslipidemia pts underwent PCI with unrestricted utilization of DESs from January 2004 to May 2011. Routine FU CAG was performed between 6 to 9 months following index PCI and was decided by individual physician’s discretion. Rests of the pts were clinically followed and ischemic driven events were captured. Clinical events including mortality, myocardial infarction and clinically driven PCI before 9 months were excluded in both groups. Cumulative clinical outcomes up to 3 years were compared between the Routine CAG group (n=329 pts) and the Clinical FU group (n= 225 pts). To adjust potential confounders, a propensity score matched (PSM) analysis was performed using the logistic regression model. Results: After PSM analysis, 2 propensity-matched groups (165 pairs, n = 330 pts, C-statistic=0.718) were generated and, the baseline characteristics of the two groups were balanced. At 3 years, the incidence of repeat revascularization and major adverse cardiac events (MACEs) was higher in the Routine CAG group than the control group (Table). Conclusions: Despite the expected beneficial effects, routine FU CAG following index PCI with DESs in dyslipidemia pts was associated with higher incidence of repeat PCI and MACE up to 3 years.

ObjectiveTo evaluate the risk of spine fracture in patients with mood disorder using a nationwide cohort.DesignA longitudinal follow-up study.SettingClaims data for the population ≥20 years of age were collected from 2002 to 2013 for the Korean National Health Insurance Service-National Sample Cohort.ParticipantsA total of 60 140 individuals with mood disorder were matched with 240 560 individuals (control group) for age, sex, income, region of residence and osteoporosis.InterventionsIn both the mood disorder and control groups, the history of spine fracture was evaluated. The International Classification of Diseases 10th Revision codes for mood disorder (F31–F39) and spine fracture (S220 and S320) were included.Primary and secondary outcome measuresThe univariable and multivariable HRs and 95% CIs of spine fracture for patients with mood disorder were analysed using a stratified Cox proportional hazards model. Subgroup analyses were conducted according to the history of osteoporosis, age and sex.ResultsApproximately 3.3% (2011/60 140) of patients in the mood disorder group and 2.8% (6795/240 560) of individuals in the control group had spine fracture (p<0.001). The mood disorder group demonstrated a higher adjusted HR for spine fracture than the control group (multivariable HR=1.10, 95% CI 1.04 to 1.15, p<0.001). The participants without osteoporosis showed a higher HR of mood disorder for spine fracture than the control participants (multivariable HR=1.25, 95% CI 1.14 to 1.37, p<0.001). According to age and sex, this result was consistent in subgroups of women aged 20–39 and 40–59 years and men aged ≥60 years.ConclusionThe risk of spine fracture was increased in patients with mood disorder. The potential risk of spine fracture needs to be evaluated when managing patients with mood disorder.

Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity. The aim of this investigation was to evaluate the effect of percutaneous chronic total occlusion (CTO) revascularization on the parameters of P wave duration and PWD on ECG in cases before and after procedure at 12th months. Methods: We analyzed 90 consecutive CTO cases who were on sinus rhythm and underwent percutaneous coronary intervention (PCI). P-wave maximum (P-max) and P-wave minimum (P-min), P-wave time, and PWD were determined before and twelve months after the CTO intervention. The study population was categorized into two groups as successful and unsuccessful CTO PCI groups. Results: The CTO PCI was successful in 71% of cases (n=64) and it was unsuccessful in 29% of cases (n=26). Both groups, except for age and hypertension, were similar in terms of demographic and clinical aspects. CRP levels were significantly elevated in the unsuccessful CTO PCI group. Pre-PCI ECG parameters showed no significant difference. Irrespective of the target vessel revascularization, we observed that PWD and P-max values were significantly lower in the 12th months follow-up. In all Rentrop classes, PWD values were significantly decreased at 12th months follow-up in comparison to the pre-CTO PCI values. Conclusion: This study has determined that PWD and P-max, which are both risk factors for atrial arrhythmias, are significantly reduced within 12th months after successful CTO PCI regardless of the target vessel.
