Abstract
BACKGROUND Percutaneous coronary intervention (PCI) is the reperfusion strategy typically used in patients with ST-segment elevation myocardial infarction (STEMI) who present with prolonged ischemic symptoms (>12 hours after onset). However, there is no consensus on an optimal time window for PCI. We examined a real-world cohort, assessing time from symptom onset to balloon inflation in relation to long-term nonfatal recurrent myocardial infarction (MI) or all-cause mortality. MATERIALS AND METHODS A total of 825 consecutive patients presenting with ischemic symptoms of STEMI >12 hours after symptom onset and undergoing subsequent primary PCI were grouped by time-to-treatment status (≤7 days or >7 days post-MI). Primary endpoints were nonfatal recurrent MI and all-cause mortality. RESULTS Cumulative rates of recurrent nonfatal MI at 2 years were 4.1% and 3.3% in patients with symptom-onset-to-balloon inflation times of ≤7 days and >7 days, respectively (P = 0.049); and corresponding mortality rates were 3.4% and 4.7% (P = 0.238). In Cox multivariate analyses, syndrome-onset-to-balloon-inflation time was not independently predictive of recurrent MI (P = 0.052) or mortality (P = 0.651) at 2 years, once adjusted for certain clinical and angiographic variables known to influence patient outcomes. The 2-year rate of recurrent MI was highest in patients with multivessel coronary artery diseases undergoing primary PCI ≤7 days after symptom onset to balloon inflation (P = 0.005). CONCLUSIONS In patients presenting with ischemic signs or symptoms of STEMI >12 hours after initial symptom onset and treated by PCI, symptom-onset-to-balloon-inflation times ≤7 days showed no relation to nonfatal recurrent MI, unless in the presence of multivessel coronary artery diseases.

Combined therapy with shock wave and autologous bone marrow-derived mesenchymal stem cells alleviates left ventricular dysfunction and remodeling through inhibiting inflammatory stimuli, oxidative stress & enhancing angiogenesis in a swine myocardial infarction model. Int J Cardiol 2015; 193:69-83. [PMID: 26025755 DOI: 10.1016/j.ijcard.2015.03.044] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2014] [Revised: 01/06/2015] [Accepted: 03/03/2015] [Indexed: 11/28/2022]
Abstract
BACKGROUND We hypothesized that combined therapy with shock wave (SW) and autologous bone marrow-derived mesenchymal stem cells (BMDMSCs) is superior to either therapy alone for alleviating left ventricular (LV) dysfunction. METHODS AND RESULTS Male mini-pigs (n=30) equally divided into group 1 (sham control), group 2 [acute myocardial infarction (AMI) by left coronary artery ligation], group 3 (AMI-SW), group 4 (AMI-BMDMSC), and group 5 (AMI-SW-BMDMSC) were sacrificed by day 60 and the hearts were collected for studies. Baseline LV injection fraction [LVEF (%)] and LV chamber size did not differ among the five groups (p>0.5). By day 60, LVEF was highest in group 1 and lowest in group 2, significantly higher in group 5 than that in groups 3 and 4, and significantly higher in group 4 than that in group 3 (p<0.001). Cellular and protein levels of VEGF, CXCR4, and SDF-1α were significantly increased progressively from groups 1 to 5 (all p<0.05). Small vessel number and protein expressions of CD31 and eNOS were highest in groups 1 and 5, lowest in group 2, and significantly higher in group 4 than those in group 3 (p<0.001). Protein (MMP-9, TNF-1α and NF-κB) and cellular (CD14+, CD40+) levels of inflammatory biomarkers, protein expressions of oxidative stress (oxidized protein, NOX-1, NOX-2), apoptosis (Bax, caspase-3, PARP), infarct size, and LV dimensions showed a pattern opposite to that of LVEF among all groups (all p<0.001). CONCLUSIONS Combined SW-BMDMSC therapy is superior to either therapy alone for improving LVEF, reducing infarct size, and inhibiting LV remodeling.

Abstract
Objectives Percutaneous coronary intervention( PCI) for ST-elevation myocardial infarction (STEMI) has been widely accepted for patient who come within 12 hours, but for those who come to the hospital late (12 hours to 28 days) the long-term data and possible predictors are limited regarding ‘hard’ endpoints in ‘real world’. Methods The registry data of all 5523 consecutive patients admitted due to an incident STEMI (12 hours to 28 days) in our center were analyzed. Patients were divided into 3 age groups (age<65; age = 65–74; age ≥75) and two therapeutic groups including conservative and PCI group. The primary endpoints included 30-day mortality and 1-year mortality. Results The clinical characteristics include female gender; history of diabetes mellitus, previous myocardial infarction, cerebral vascular disease, chronic renal failure, atrial fibrillation, hypertension, anemia, gastric bleeding; presentation of ventricular tachycardia/ventricular fibrillation, pneumonia, heart failure, multiple organ failure and cardiogenic shock. The ratio of all the above factors increased with the age getting older (all p<0.05), while that of the PCI decreased significantly with ageing (53.9%, 36.3% and 21.7%). Except hypertension, all the other factors were less seen in the PCI group than in the conservative group (p<0.01). Pooled estimates, based on type of therapy and age groups, PCI resulted in significantly lower 30-day and 1-year mortality. Cox analysis showed the positive predictors for 30 days and 1 year mortality were heart failure, cerebral vascular disease, chronic renal failure, ventricular tachycardia/ventricular fibrillation, age, female, gastric intestinal bleeding, cardiogenic shock, multiple organ failure, while PCI was a negative predictor. ROCs analysis showed AUCs were always higher for PCI group. Conclusions The elderly have more comorbidities and higher rates of mortality, mandating thorough evaluation before acceptance for PCI. PCI between 12 hours to 28 days in all ages of patients including the elderly with STEMI is significantly more effective than conservative therapy.

Abstract
OBJECTIVE To find the optimal time (early: < or =3 days; late: >3 days) for revascularization in ST elevation myocardial infarction (STEMI) patients in the subacute phase. METHODS Ninety-nine STEMI patients who were admitted to Gazi University Faculty of Medicine between 2000 and 2004 were enrolled into this study. Patients were divided into 2 groups according to time from the beginning of symptoms to the percutaneous coronary intervention. Coronary angiograms before and after the revascularization were evaluated using the quantitative coronary angiogram technique. RESULTS 45 early (group I) and 54 late (group II) revascularized patients were evaluated. There were no significant differences between the 2 groups regarding demographic properties, thrombus score, success of the procedure, quantitative angiographic parameters, and clinical results of the procedure. CONCLUSIONS Waiting for the development of stable phase in STEMI to apply PCI has no obvious benefit for angiographic and clinical results.

Abstract
Second-degree heart block or complete heart block (CHB) is a relatively frequent complication of acute inferior wall myocardial infarction (AIWMI). This study investigated whether the PercuSurge device can prevent procedure-related CHB or can shorten CHB recovery time in patients with AIWMI undergoing primary percutaneous coronary intervention (PCI). Between May 2002 and April 2005, a PercuSurge device was utilized in 113 patients (study population, group 1) with AIWMI due to obstruction of the right coronary artery (RCA) with a reference lumen diameter (RLD) > or = 3.5 mm. The control subjects (group 2) consisted of 119 patients who experienced AIWMI due to RCA obstruction with a RLD > or = 3.5 mm from May 2000 to April 2002. The combined incidence of new onset of CHB following the interventional procedure was significantly higher in group 2 than in group 1. Additionally, recovery time from CHB to first-degree heart block or normal sinus rhythm was remarkably longer in group 2 than in group 1. Furthermore, the duration of hospitalization in group 2 was significantly longer than in group 1. Multiple stepwise analyses demonstrated that the PercuSurge device was the only independent predictor of preventing new onset of CHB during the procedure. Additionally, this mechanical device along with final TIMI-3 flow and final myocardial blush grade > or = 2 was independently associated with reducing recovery time from CHB. In conclusion, the PercuSurge device can prevent procedure-related CHB and shorten the recovery time for CHB in patients with AIWMI undergoing primary PCI.

Abstract
BACKGROUND The link between increased circulating level of endothelin (ET)-1 and adverse clinical outcomes after acute myocardial infarction (AMI) has been established. Current studies demonstrate that reperfusion therapy by either thrombolysis or primary percutaneous coronary intervention (PCI) can salvage myocardium, improving survival of AMI patients. However, whether reperfusion therapy by primary PCI can prevent the adverse effect of ET-1 on clinical outcomes in patients after AMI remains unclear. Therefore, this study examined the predictive value of circulating ET-1 levels on 30-day outcomes in ST-segment elevated AMI treated with primary PCI. METHODS AND RESULTS We conducted a prospective cohort study of 186 consecutive patients with ST-segment elevated AMI of onset < 12 h who underwent primary PCI. Blood samples for plasma concentration of ET-1 were collected in the catheterization laboratory following vascular puncture. Patients were classified into a high group (group 1, ET-1 level >or= 0.632 pg/mL, n = 93) and a low group (group 2, ET-1 level < 0.632 pg/mL, n = 93) according to the median value of ET-1 after AMI. Univariate analysis demonstrated that the 30-day composite major adverse clinical outcomes (MACO) [advanced Killip score >or= 3], severe congestive heart failure (CHF) [New York Heart Association functional class 4], and 30-day mortality were strongly associated with high ET-1 level (>or= 0.632 pg/mL; p < 0.0001), unsuccessful reperfusion (final Thrombolysis in Myocardial Infarction flow <or= 2; p < 0.0001), low left ventricular ejection fraction (< 50%; p = 0.0002), multivessel disease (p = 0.005), and female gender (p = 0.007). Multiple stepwise logistic regression analysis demonstrated that only high ET-1 level (p < 0.0001) and unsuccessful reperfusion (p < 0.0001) were independent predictors of 30-day MACO. Additionally, high ET-1 level (p = 0.0021) along with unsuccessful reperfusion (p = 0.008) and severe CHF (p < 0.0001) were significant independent predictors of increased 30-day mortality. CONCLUSIONS A high circulating level of ET-1 is a strong independent predictor of 30-day MACO after ST-segment elevated AMI treated with primary PCI.

Abstract
BACKGROUND This study tested the hypothesis that serum concentrations of high-sensitivity C-reactive protein (hs-CRP) and soluble CD40 ligand (sCD40L) significantly reflect serial changes in patients with unstable angina, and thus the serum concentrations of these inflammatory biomarkers may be good candidates for predicting late restenosis after coronary stenting. METHODS AND RESULTS The circulating concentrations of sCD40L and hs-CRP were prospectively measured (both pre-procedure, and on days 21, 90, and 180 after the procedure) in 77 consecutive patients with unstable angina undergoing coronary stenting. These inflammatory mediators were also evaluated in 30 healthy volunteers. The serum concentrations of sCD40L and hs-CRP were significantly higher pre-procedure in study patients than in normal control subjects (all p values < 0.0001). These inflammatory markers then declined to a substantially lower concentration by day 21 (all p values < 0.05). Circulating concentrations of hs-CRP in each patient then differed little from each other afterwards. However, the sCD40L concentration was once again raised significantly on days 90 and 180 as compared to day 21 (both p values < 0.05). This study found no significant link between raised circulating concentrations of sCD40L and hs-CRP and late restenosis. CONCLUSIONS Circulating concentrations of sCD40L and hs-CRP were significantly increased in unstable angina patients pre-procedure and declined substantially thereafter. However, the circulating concentrations of these 2 inflammatory mediators were not useful in predicting late restenosis following coronary stenting.

Abstract
Inflammation plays an important pathogenic role in the initiation and progression of atherosclerotic plaque lesions. C-reactive protein (CRP), which directly participates in plaque inflammation, induces vascular cell adhesion molecule-1 (VCAM-1) expression in endothelial cells. However, the levels and values of high-sensitivity (hs)-CRP, white blood cell (WBC) count, and VCAM-1 in both stable and unstable angina pectoris (AP) have not been fully investigated. This study examines the levels and values of these inflammatory markers in patients with stable or unstable AP. From March 2003 to December 2003, a prospective cohort study was conducted in 128 consecutive patients, including unstable AP patients (class I: n = 59; combined class II and III: n = 16) and stable AP patients (n = 53) undergoing elective coronary stenting. Blood samples for hs-CRP, WBC count, and VCAM-1 were obtained in the catheterization laboratory before coronary angiography. The circulating levels of hs-CRP and VCAM-1 were also evaluated in 40 healthy volunteers. The circulating levels of these three inflammatory markers were substantially higher in patients than in healthy volunteers (all P values < 0.0001). Additionally, circulating levels of hs-CRP and the WBC count were significantly higher in patients with unstable AP than in patients with stable AP (all P value < 0.0001). However, only those patients with class II and III unstable AP had significantly higher circulating levels of VCAM-1 than patients with stable AP (P < 0.0001). On the other hand, the circulating levels of VCAM-1 did not differ between patients with class I unstable AP and patients with stable AP (P = 0.782). Multiple stepwise logistic regression analysis showed that only hs-CRP level was independently associated with unstable AP (P = 0.0002). In conclusion, circulating levels of hs-CRP, WBC count, and VCAM-1 were significantly increased in patients with AP. The circulating level of hs-CRP was strongly associated with the clinical setting of unstable AP.
