BACKGROUND Stable coronary artery disease is caused by a variable combination of organic coronary stenosis and functional coronary abnormalities, such as coronary artery spasm. Thus, we examined the clinical importance of comorbid significant coronary stenosis and coronary spasm. METHODS AND RESULTS We enrolled 236 consecutive patients with suspected angina who underwent acetylcholine provocation testing for coronary spasm and fractional flow reserve (FFR) measurement. Among them, 175 patients were diagnosed as having vasospastic angina (VSA), whereas the remaining 61 had no VSA (non‐VSA group). The patients with VSA were further divided into the following 3 groups based on angiography and FFR: no organic stenosis (≤50% luminal stenosis; VSA‐alone group, n=110), insignificant stenosis of FFR>0.80 (high‐FFR group, n=36), and significant stenosis of FFR≤0.80 (low‐FFR group, n=29). The incidence of major adverse cardiovascular events, including cardiovascular death, nonfatal myocardial infarction, urgent percutaneous coronary intervention, and hospitalization attributed to unstable angina was evaluated. All patients with VSA received calcium channel blockers, and 28 patients (95%) in the low‐FFR group underwent a planned percutaneous coronary intervention. During a median follow‐up period of 656 days, although the incidence of major adverse cardiovascular events was low and comparable among non‐VSA, VSA‐alone, and high‐FFR groups, the low‐FFR group had an extremely poor prognosis (non‐VSA group, 1.6%; VSA‐alone group, 3.6%; high‐FFR group, 5.6%; low‐FFR group, 27.6%) ( P <0.001). Importantly, all 8 patients with major adverse cardiovascular events in the low‐FFR group were appropriately treated with percutaneous coronary intervention and calcium channel blockers. CONCLUSIONS These results indicate that patients with VSA with significant coronary stenosis represent a high‐risk population despite current guideline‐recommended therapies, suggesting the importance of routine coronary functional testing in this population.

Calcified Coronary Lesions

Despite advances in technology, percutaneous coronary intervention (PCI) of severely calcified coronary lesions remains challenging. Rotational atherectomy is one of the current therapeutic options to manage calcified lesions, but has a limited role in facilitating the dilation or stenting of lesions that cannot be crossed or expanded with other PCI techniques due to unfavourable clinical outcome in long-term follow-up. However the results of orbital atherectomy presented in the ORBIT I and ORBIT II trials were encouraging. In addition to these encouraging data, necessity for sufficient lesion preparation before implantation of bioresorbable scaffolds lead to resurgence in the use of atherectomy. This article summarises currently available publications on orbital atherectomy (Cardiovascular Systems Inc.) and compares them with rotational atherectomy.

Objectives The deleterious effects of psychological problems on coronary heart disease (CHD) are not satisfactorily explained. We explored influential factors associated with mortality in psycho-cardiological disease in a Chinese sample. Methods Of 7460 cardiac patients, we selected 132 patients with CHD and mental illness. Follow-up was conducted via telephone. We analyzed clinical characteristics, clinical outcomes, and survival. Results The clinical detection rate of psycho-cardiological disease in the overall patient population was 1.8%. Of these, 113 patients completed follow-up; 18 died owing to cardiovascular diseases during follow-up. Kaplan–Meier analysis showed dysphagia, limb function, self-care ability, percutaneous coronary intervention, low-density lipoprotein, total cholesterol, pro-brain natriuretic peptide and high-sensitivity (hs) troponin T had significant associations with cumulative survival. Cox regression analysis showed total cholesterol (hazard ratio [HR]: 2.765, 95% confidence interval [CI]: 1.001–7.641), hs troponin T (HR: 4.668, 95% CI: 1.293–16.854), and percutaneous coronary intervention (HR: 3.619, 95% CI: 1.383–9.474) were independently associated with cumulative survival. Conclusions The clinical detection rate of psycho-cardiological disease was far lower than expected. Normal total cholesterol and hs troponin T were associated with reduced cardiovascular disease mortality over 2 years. Percutaneous coronary intervention is a prognostic risk factor in patients with psycho-cardiological disease.

Abstract Background Associations between D-dimer and outcomes of patients with acute coronary syndromes (ACS) remain controversial. This study aimed to investigate the prognostic value of D-dimer in ACS patients treated by percutaneous coronary intervention (PCI). Methods In this observational study, 3972 consecutive patients with ACS treated by PCI were retrospectively recruited. The X-tile program was used to determine the optimal D-dimer thresholds for risk stratifications. Cox regression with multiple adjustments was used for outcome analysis. Restricted cubic spline (RCS) analysis was performed to assess the dose-response association between D-dimer and outcomes. The C-index was calculated to evaluate the additional prognostic value of D-dimer when added to clinical risk factors and commonly used clinical risk scores, with internal validations using bootstrapping methods. The primary outcome was all-cause death. Results During a median follow-up of 720 days, 225 deaths occurred. Based on the thresholds generated by X-tile, ACS-PCI patients with median (420–1150 ng/mL, hazard ratio [HR]: 1.58, 95 % confidence interval [CI]: 1.14–2.20, P = 0.007) and high (≥ 1150 ng/mL, HR: 1.98, 95 % CI: 1.36–2.89, P < 0.001) levels of D-dimer showed substantially higher risk of death compared to those with low D-dimer (< 420 ng/mL). RCS analysis depicted a constant relation between D-dimer and various outcomes. The addition of D-dimer levels significantly improved risk predictions for all-cause death when combined with the fully adjusted models (C-index: 0.853 vs. 0.845, P difference = 0.021), the GRACE score (C-index: 0.826 vs. 0.814, P difference = 0.027), and the TIMI score (C-index: 0.804 vs. 0.776, P difference < 0.001). The predicted mortality at the median follow-up (two years) was 1.7 %, 5.2 %, and 10.9 % for patients with low, median, and high D-dimer, respectively, which was well matched with the observed mortality (low D-dimer group: 1.2 %, median D-dimer group: 5.2 %, and high D-dimer group: 12.6 %). Conclusions For ACS patients treated by PCI, D-dimer level was an independent predictor for adverse outcomes, and provided additional prognostic value when combined with clinical risk factors and risk scores. Risk stratifications based on D-dimer was plausible to differentiate ACS-PCI patients with higher risk of death.

Background: The treatment of LMCAD has shifted from coronary artery bypass grafting (CABG) to Percutaneous coronary intervention (PCI). However, data on long-term outcomes of PCI for LMCA disease, especially in patients with acute coronary syndrome (ACS) remains limited and conicting. This study aims to nd the association of the immediate and 4-year mortality in ACS patients with LMCA disease treated by PCI based on ejection fractions at admission. Methods: A retrospective analytical study was conducted. Patients were divided at admission into those with reduced left ventricular ejection fraction and those with preserved ejection fraction. Results: Forty (58.8%) of the patients presented with preserved EF. The mean age of the patients was 71.6±7.1 years. The mean LVEF of the preserved group was 61.6±4.3% and signicantly higher than that of the reduced group. Age and cardiovascular risk factor prole was similar between the two groups. Patients with reduced ejection fraction had signicantly higher levels of serum creatinine and signicantly lower levels of Hb and HDL. Mean hospital stay was signicantly longer for patients with preserved EF. In-hospital deaths were also similar between the two groups. The reduced EF group had a signicantly higher allcause mortality in the 4-year follow-up period. The mean years of follow-up for all participants was 4.2±1.3 years. Conclusion: It was seen that in patients presenting with ACS and undergoing PCI due to LMCAD, LVEF at admission, singly and in in multivariate regression is an important predictor of in hospital and 4-year mortality

Background: The ostial left anterior descending coronary artery (LAD) lesion is an important target for coronary revascularization because its location subtends a large territory of myocardium. Ostial lesions have a reputation of being fibrotic, calcified, and relatively rigid. Greater degraees of rigidity and recoil resulted in lower acute gain and higher rates of target lesion revascularization (TLR) following percutaneous coronary intervention (PCI). In addition, procedural complications such as dissections, vessel closure and myocardial infarction were more frequent. Aim of the study was to evaluate a simple but innovative technique to deal with significant LAD ostial lesion.Methods: This prospective study was conducted between January 2010 and February 2013. Patients with significant angiographic de novo ostial LAD artery stenoses were identified and screened for study eligibility. An ostial stenosis was defined as an angiographic narrowing of e” 70% located within 3 mm of the vessel origin. Study included all consecutive patients with ostial lesions who underwent elective PCI and stent deployment. The study population consisted of 36 patients.Results: Among 36 patients 27 (75%) were male. mean age was 55.75 ± 8.07 years. 21 (58.3%) had diabetes, 15 (41.7%) hypertension, 21 (58.3%) hypercholesterolemia, 24 (66.66%) were smoker and 18 (50%) had F/H of CAD. Among them 6 (16.7%) had STEMI, 9 (25%) had NSTEMI, 12 (33.3%) had UA and 9 (25%) CSA. CAG showed 15 (41.7%) SVD, 15 (41.7%) DVD and 6 (16.7%) were TVD. LAD ostial stenosis were 83.16 ± 10.14%. Considering procedural characteristics, DES were 33 (91.7%) and BMS were 3 (8.3%). DES polymers were Evarolimus 15 (41.7%), Zotarolimus 12 (33.3%) and Biolimus 6 (16.7%). Mean stent length were 21.75 ± 8.07 mm. Mean stent diameter were 2.83 ± 0.28 mm. Minimum follow up time was 9 months and maximum follow up time was 44 months. There were no MACE but Angina (CCS II) were 2 (5.55%) and LVF (NYHA II) were 1(2.77%).Conclusion: Precise placement of LAD ostial stent is always challenging. Several technique applied but results not always satisfactory. Our strategies were precise location of stent implantation at ostium by adopting special technique of simultaneous balloon placement from distal LM to proximal LCX preventing unwanted stent movement during its placement and also properly guiding us for precise stent placement at the ostium. Parked balloon from distal LM to LCX will also be helpful for quick measure for any plaque shifting into LCX.Cardiovasc. j. 2016; 9(1): 49-54
