Cardiovascular outcomes of complex bifurcation lesions following double kissing crush or nano-crush techniques: The multicenter EVOLUTE-CRUSH V study.

BACKGROUND: Double kissing crush (DKC) and nano-crush (NC) techniques are frequently used, but the comparison for both techniques is still lacking. The goal of this multicenter study was to retrospectively assess the midterm clinical results of DKC and NC stenting in patients with complex bifurcation lesions (CBLs). METHODS: A total of 324 consecutive patients [male: 245 (75.6%), mean age: 60.73 ± 10.21 years] who underwent bifurcation percutaneous coronary intervention between January 2019 and May 2023 were included. The primary endpoint defined as the major cardiovascular events (MACE) included cardiac death, target vessel myocardial infarction (TVMI), or clinically driven target lesion revascularization (TLR). Inverse probability weighting (IPW) was performed to reduce treatment selection bias. This is the first report comparing the clinical outcomes of DKC and NC stenting in patients with CBL. RESULTS: The initial revascularization strategy was DKC in 216 (66.7%) cases and NC in 108 (33.3%) patients. SYNTAX scores [25.5 ± 6.73 vs. 23.32 ± 6.22, p = 0.005] were notably higher in the NC group than the DKC group. The procedure time (76.98 ± 25.1 vs. 57.5 ± 22.99 min, p = 0.001) was notably higher in the DKC group. The incidence of MACE (18.5 vs. 9.7%, p = 0.025), clinically driven TLR (14.8 vs. 6%, p = 0.009), and TVMI (10.2 vs. 4.2%, p = 0.048) were notably higher in the NC group than in the DKC group. The midterm MACE rate in the overall population notably differed between the NC group and the DKC group (adjusted HR (IPW): 2.712, [95% CI: 1.407-5.228], p = 0.003). CONCLUSION: In patients with CBLs, applying the DKC technique for bifurcation treatment had better ischemia-driven outcomes than the NC technique.

Assessment of electrocardiographic criteria for the diagnosis of left ventricular hypertrophy in the octogenarian population.

BACKGROUND: Although there are several electrocardiographic (ECG) diagnostic criteria for identifying left ventricular hypertrophy (LVH), the sensitivity of these criteria remains low. Recently, the Peguero-Lo Presti criterion provides a higher sensitivity than the current criteria. We aimed to test this ECG criterion prospectively, in the octogenarian population. METHODS: We prospectively enrolled outpatients over 80 years of age who were referred to our echocardiography laboratory. The Peguero-Lo Presti criterion was assessed along with other established ECG criteria. Left ventricular mass was calculated by echocardiography. Performance of ECG indices in diagnosing LVH were evaluated. RESULTS: Overall, 119 patients were included in the study. The sensitivity and specificity of the Peguero-Lo Presti criterion were 62.5% and 87.3%, respectively. In addition, the highest sensitivity belonged to the Peguero-Lo Presti criterion, and the highest AUC value was also seen in this criterion (AUC: 0.787, 95% CI, 0.698-0.876, P < .001). CONCLUSION: The Peguero-Lo Presti criteria showed the highest sensitivity for LVH detection, and it outperformed the other validated criteria in this octogenarian population. The Peguero-Lo Presti criteria seemed to be more effective for diagnosing LVH in this setting.

Treatment of Simultaneous Thromboembolism of the Right and Left Coronary Arteries with Thrombus Aspiration in a Patient with a Prosthetic Mitral Valve.

Prosthetic heart valve thrombosis is a rare, difficult-to-treat condition that increases morbidity and mortality by leading to systemic embolism. Clinically, it presents mainly in the form of stroke, though an embolism be observed in many systems. Acute coronary syndrome, which is rarely observed in patients with a prosthetic heart valve, mostly occurs as non-ST segment elevation myocardial infarction (MI). There is no specific recommendation for the treatment of this condition. Revascularization success rates have been shown to be variable in cases wherein thrombolytic therapy, balloon angioplasty, stent implantation, and a combination of all of these techniques are used. Herein are presented details of the successful revascularization of a patient with ST segment elevation MI presenting with simultaneous right and left coronary system embolism, and without embolism in any other system. In cases of acute coronary syndrome in patients with a prosthetic heart valve with no known coronary artery disease, starting the procedure with thrombus aspiration may prevent unnecessary stent and balloon angioplasty procedures being required, by accelerating the revascularization process.

Persistent smoking rate after coronary revascularization and factors related to smoking cessation in Turkey.

Background: Although smoking is an established risk factor for coronary artery disease, smoking cessation efforts, as part of a lifestyle change, have been disappointing so far. Therefore, assessing current smoking trends and identifying patients who are at risk of smoking continuation is of paramount importance. In this study, our aim was to assess current smoking rates after coronary revascularization as of 2017, and to define factors that potentially affect smoking cessation. Methods: Overall, 350 patients who had undergone coronary revascularization, either by percutaneous coronary intervention or bypass surgery were included in this cross-sectional, observational study. Patients were queried for various sociodemographic characteristics and smoking habits. Disease related data were obtained from the hospital archives. Results: The overall smoking rate was 57% after coronary revascularization. Age, bypass surgery and the occurrence of in-hospital adverse events were found to be independent predictors of smoking cessation in multivariate analysis. Conclusions: Despite efforts, smoking rates after coronary intervention remain substantially high. Therefore, a multidisciplinary approach to smoking cessation that incorporates cardiac rehabilitation programs and medications should be implemented in clinical practice.

Usefulness of Serum Omentin-1 Levels for the Prediction of Adverse Cardiac Events in Patients with Hypertrophic Cardiomyopathy.

OBJECTIVE: To investigate the association between serum omentin-1 levels and adverse cardiac events in patients with hypertrophic cardiomyopathy (HCM). SUBJECTS AND METHODS: This prospective, observational study included 87 patients with HCM and 50 age- and sex-matched control subjects. Serum omentin-1 and brain natriuretic peptide (BNP) levels were measured in all subjects, using enzyme-linked immunosorbent assay and electrochemiluminescence, respectively. Patients with HCM were divided into 2 groups according to their omentin levels, i.e., low: ≤291 ng/mL (n = 48) and high: > 291 ng/mL (n = 39). Cardiac mortality, hospitalization due to heart failure, and implantable cardioverter-defibrillator (ICD) implantation were considered adverse cardiac events. Statistical analysis included uni- and multivariant logistic regression, receiver-operating characteristic (ROC) analysis, and the Kaplan-Meier method. RESULTS: Serum omentin-1 levels were significantly lower in the obstructive (253.9 ± 41.3 ng/mL) and nonobstructive (301.9 ± 39.8 ng/mL) HCM groups than in the control group (767.1 ± 56.4 ng/mL), p < 0.001, respectively. The BNP levels were higher in the obstructive and nonobstructive HCM groups than in the control group (269.5 ± 220, 241.0 ± 227, and 24.0 ± 18.9 pg/mL, respectively, p < 0.001). The Kaplan-Meier analysis indicated that patients with low omentin-1 levels showed a significantly higher (48.2%) 2-year cumulative incidence of overall adverse cardiac events than those with high omentin-1 levels (16.2%) (log-rank test, p = 0.001). In the multivariate logistic regression analysis, omentin-1, interventricular septum (IVS) thickness, and male gender were independent predictors of adverse cardiac events in the follow-up. CONCLUSION: Omentin-1 levels were lower in patients with HCM than in the control group, and this was associated with worse cardiac outcomes.

The Value of CHA2DS2VASC Score in Predicting All-Cause Mortality in Patients with ST-Segment Elevation Myocardial Infarction Who Have Undergone Primary Percutaneous Coronary Intervention.

BACKGROUND: Acute coronary syndrome is the most common cause of cardiac morbidity and death. Various scoring systems have been developed in order to identify patients who are at risk for adverse outcome and may benefit from more aggressive and effective therapies. OBJECTIVES: This study was designed to evaluate the CHA2DS2VASC score as a predictor of mortality inpatients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (p-PCI). METHODS: We evaluated 300 patients diagnosed with ST-elevation myocardial infarction who underwent p-PCI and calculated their CHA2DS2VASC scores. According to their CHA2DS2VASC scores, patients were divided into three groups. Group 1: 0-1 points (n = 101), Group 2: 2-3 points (n = 129), and Group 3: 4-9 points (n = 70). The mean, median and minimum duration of follow-up were 21.7 ± 9.4, 21, and 12 months, respectively. All-cause mortality was defined as the primary endpoint of the study. RESULTS: All-cause mortality was 4% in Group 1, 8.5% in Group 2 and 27.1% in Group 3 respectively. Kaplan-Meier analysis showed that Group 3 (CHA2DS2VASC ≥ 4) had a significantly higher incidence of death [p (log-rank) < 0.001]. In ROC analysis, AUC values for in hospital, 12-month and long-term mortality were 0.88 (0.77-0.99 95% CI), 0.82 (0.73-0.92 95% CI) and 0.79 (0.69-0.88 95% CI), respectively. CONCLUSIONS: CHA2DS2VASC score can be used for predicting both in-hospital, 12-month and long-term mortality in patients with STEMI who have undergone p-PCI.

Resistant spontaneous coronary artery spasm.

Coronary artery spasm should always be suspected in patients who have myocardial infarction with normal coronary arteries. This case report presents a 33-year-old woman with anterior myocardial infarction, whose coronary angiograph revealed normal left anterior descending artery and new onset complete occlusion of the circumflex artery at the time of the procedure. Nitroglycerin up to 800 mcg was administered without success. In such resistant cases, when all efforts fail, including prompt recognition and application of vasodilator drugs, retracting the catheter and waiting may play a role.

A rare cause of chest pain mimicking myocardial infarction.

We present a patient who underwent endoscopic retrograde cholangiopancreatography procedure for bile duct stone removal and sphincterotomy. Upon completion of the procedure, the patient experienced severe chest pain. Because myocardial infarction was the likely diagnosis, we immediately performed a coronary angiography, which identified severe coronary lesions without any total occlusion. Being skeptical of the possible cause, we searched for alternative causes and interestingly found pneumothorax, pneumomediastinum, and retro-intra-abdominal free air. This rare complication is particularly important for a cardiologist because they should be aware of such a complication, and correlation with the symptoms and coronary lesions should always be made.

The Impact of Combination of Aerobic and Resistive Exercise on Activities of Daily Living and Risk of Fall in Osteosarcopenic Patients.

Objectives: It is aimed to explain the impact of the combination of aerobic and resistive exercise on activities of daily living and the risk of falls in osteosarcopenic patients. Methods: Female and male patients over 70 years of age followed up from the osteoporosis outpatient clinic were screened. Appropriate patients were evaluated for sarcopenia gait speed, grip strength and skeletal muscle mass. Patients with sarcopenia who did not have the exclusion criteria were included in the 3-month aerobic and resistive exercise program. Changes in skeletal muscle mass measurements, physical performance and balance tests were evaluated at 1 month and 3 months. Results: Sarcopenia was screened in 91 patients with osteoporosis and osteopenia. Sarcopenia was detected in 27 patients and 23 completed the 3-month study. The mean age of the patients was 78.4±5.7 years and the number of female patients was 16 (69.6%). There was no significant change in skeletal muscle mass measurements and Katz Activities of Daily Living Scale performed at 1 and 3 months (p>0.05). Short Physical Performance Battery (SPPB), Timed Up and Go Test (TUGT) and Berg Balance Test (BBT) were found to improve significantly in the first month, and it continued to develop in the third month (p<0.05). Conclusion: Although the combination of aerobic and resistive exercise in osteosarcopenic patients did not lead to a significant increase in skeletal muscle mass, It has a significant effect on physical performance and balance. It can be foreseen that this will increase the independence of the person while reducing the risk of falling.

A Novel Score for an Old Enemy: Atherogenic Plasma Index Predicts In-Stent Restenosis among Stable Angina Pectoris Patients.

Objectives: Although the association of Atherogenic index of plasma (AIP) with coronary artery disease (CAD) and atherosclerosis is known, the relationship between AIP and in-stent restenosis (ISR) remains unclear. We aimed to investigate the relationship between AIP and ISR in patients with stable angina pectoris (SAP) treated with drug-eluting stent (DES). Methods: Patients with a history of DES implantation following stable angina were evaluated between January 2015 and November 2019 in this observational and retrospective study. 608 eligible patients were dichotomized into ISR+ (n=241) and ISR- (n=367). ISR was defined as the presence of 50% or greater stenosis. AIP was defined as log [TG/HDL-C]. Results: AIP levels were significantly higher in patients who developed ISR compared with those who did not (0.33 [0.15-0.52] vs 0.06 [-0.08-0.21] respectively, p<0.001). The AUC value of AIP levels for predicting ISR was 0.746 (p<0.001). Multivariate logistic regression analysis revealed that AIP, diabetes mellitus, higher LDL-C levels and lower LVEF values were independently associated with ISR. Conclusion: Multivariate analysis revealed that AIP was strongly independently associated with ISR. Using this novel inexpensive and easily calculable index may provide early recognition of ISR in patients with SAP who were treated with DES.

Evaluation of Cognitive Functions in Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention: A Prospective Pilot Study.

PURPOSE: It is not clear whether cognitive functions are impaired in young patients with acute coronary syndrome (ACS). This study aims to detect whether or not there is cognitive impairment and cerebral changes in young patients with ACS undergoing percutaneous coronary intervention (PCI). PATIENTS AND METHODS: All 50 patients with ACS who were treated with primary PCI were eligible for this prospective study. All participants had normal cognitive function before ACS. Brain magnetic resonance imaging (MRI) was performed to quantify changes in brain white and gray matter. Cognitive functions (CFs) were evaluated by seven cognitive tests. Patients were categorized by MRI findings and test scores were compared from the first day to after the first month. RESULTS: We determined 25 patients with impaired CFs on the first day. After the first month, we identified 18 patients with transient impaired CFs. No structural difference was observed between impaired CF and normal CF. While 25 patients had a score of 1 according to Fazekas, 10 patients had a score of 1 according to MTLA. While the mean Stroop test completion time and Stroop test error rate scores were significantly higher on the first day than after the first month in the Fazekas+ group (p = 0.003, p < 0.001, respectively), other cognitive test scores-except clock drawing test, digital span forwards, and backwards-were significantly lower on the first day compared to after the first month in the Fazekas+ group (p < 0.05). CONCLUSIONS: Patients with ACS have transient impairment in cognitive functions. Acute coronary syndrome is not associated with structural changes in the brain.

Iliac artery perforation and treatment during lumbar disc surgery by simple balloon tamponade.

INTRODUCTION: Although vascular injury during lumbar disc surgery is quite rare, it may be life threatening if not recognized and treated immediately. CASE: We report the case of a woman who had a left common iliac artery laceration during spinal surgery and was treated by endovascular therapy. In the past, open surgery was the only way to repair a vascular injury, but thanks to the advance of new endovascular techniques and devices, endovascular therapy has become a strong alternative. CONCLUSION: This case differs from those published in the literature as we used a single balloon inflation and subtotal occlusion without the need for a covered stent.

Percutaneous antegrade transarterial treatment of traumatic radial arteriovenous fistula.

Traumatic arteriovenous fistulas (AVF) are almost exclusively the result of penetrating trauma and there is usually a history of hemorrhage. Typically, the patient demonstrates a thrill and bruit over the site of injury. We report a woman who presented with longstanding pain and swelling of the right hand due to radial AVF that possibly occurred following an injury to the right hand that happened 10 years prior to the date of admission. Since surgery was considered high risk due to multiple fistulas and previous surgery, percutaneous coil embolization was performed via the ipsilateral antegrade radial approach.

Effects of Atrioventricular Blocks in Acute Coronary Syndrome: Long-Term Follow-Up.

Objectives: Arrhythmias are the common, potentially lethal, and treatable complication of acute coronary syndrome (ACS). Arrhythmic findings of ischemic cardiac events are well-known, but long-term results have not been scrutinized. In the study, we aimed to analyze the long-term findings of the atrioventricular block (AVB) in ACS patients. Methods: This is a single-center and retrospective study of patients admitted with ACS and AVB. The primary endpoint has combined the outcome of major adverse cardiovascular events and mortality. Results: Seventy-six (89.4%) patients had 3rd-degree AVB. Fifty (58.8%) patients are needed for temporary ventricular pacing and 4 (4.7%) for a permanent pacemaker. Although no cardiac death occurred during the 5-year follow-up period, the in-hospital mortality ratio was 30.6%. Patients with older age and lower systolic blood pressure (SBP) levels had higher mortality rates (respectively, odds ratio [OR] 1.088, [p=0.003], OR 0.912, [p<0.001]). Even in ST-segment elevation myocardial infarction and complete AVB subgroup analyses, mortality rates were associated with SBP and age (respectively, OR: 0.917, [p<0.001], OR: 1.107 [p=0.002]), (respectively, OR: 0.917 [p<0.001], OR: 1.087 [p=0.004]). Conclusion: The study results are associated with a better long-term overall prognosis in patients with ACS with AVB, but lower SBP and older in-hospital follow-up are associated with poor prognosis.

Microvascular Dysfunction in COVID-19 Patients with Acute Coronary Syndrome.

Objective: Coronavirus disease 2019 (COVID-19) is considered to deteriorate endothelial function through hyperinflammation. We aimed to investigate microvascular dysfunction using the angiographic parameters thrombolysis in myocardial infarction frame count (TFC) and myocardial blush grade (MBG), in COVID-19 patients with acute coronary syndrome (ACS). Methods: One hundred and sixty-five patients presented with ACS (62.4% ST elevated myocardial infarction) and underwent percutaneous coronary intervention between March 1 and June 30, 2020, were enrolled in the study. The polymerase chain reaction test was performed in case of suggestive symptoms or typical computerized tomography findings. Results: Twenty-six patients (15.7%) were tested positive for COVID-19. Significantly higher values were observed in TFC in patients with COVID-19 (p<0.001), whereas COVID-19 patients had significantly lower MBGs (Grade 0 and 1) (p<0.001). Peak troponin-I value was also higher in the COVID-19 group (27335 vs. 15959 ng/dL, p=0.006). Mortality risk was higher in COVID-19 patients (38.4% vs. 7.2%, p<0.001). TFC and ejection fraction may predict in-hospital mortality among COVID-19 patients with ACS according to logistic regression results. In correlation analysis, TFC correlated positively with C-reactive protein (r=0.340, p<0.001) and peak troponin-I value (r=0.369, p<0.001). Conclusion: COVID-19 is associated with slow coronary flow and microvascular impairment in ACS.

Effect of Sacubitril/Valsartan Combined with Dapagliflozin on Long-Term Cardiac Mortality in Heart Failure with Reduced Ejection Fraction.

The angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril/valsartan and sodium-glucose cotransporter-2 (SGLT-2) inhibitor dapagliflozin have been shown to reduce rehospitalization and cardiac mortality in patients with heart failure (HF) with reduced ejection fraction (HFrEF). We aimed to compare the long-term cardiac and all-cause mortality of ARNI and dapagliflozin combination therapy against ARNI monotherapy in patients with HFrEF. This retrospective study involved 244 patients with HF with New York Heart Association (NYHA) class II-IV symptoms and ejection fraction ≤40%. The patients were divided into 2 groups: ARNI monotherapy and ARNI+dapagliflozin. Median follow-up was 2.5 (.16-3.72) years. One hundred and seventy-five (71.7%) patients were male, and the mean age was 65.9 (SD, 10.2) years. Long-term cardiac mortality rates were significantly lower in the ARNI+dapagliflozin group (7.4%) than in the ARNI monotherapy group (19.5%) (P = .01). Dapagliflozin [Hazard Ratio (HR) [95% Confidence Interval (CI)] = .29 [.10-.77]; P = .014] and left ventricular ejection fraction (LVEF) [HR (95% CI) = .89 (.85-.93); P < .001] were found to be independent predictors of cardiac mortality. Our study showed a significant reduction in cardiac mortality with ARNI and dapagliflozin combination therapy compared with ARNI monotherapy.

Periprocedural, Short-Term, and Long-Term Outcomes of Alcohol Septal Ablation in Patients with Hypertrophic Obstructive Cardiomyopathy: A 20-Year Single-Center Experience.

BACKGROUND: Alcohol septal ablation is recommended for hypertrophic obstructive cardiomyopathy patients who had refractory symptoms despite optimal medical treatment. We compared the periprocedural, short-, and long-term clinical outcomes and mortality predictors in hypertrophic obstructive cardiomyopathy patients who underwent alcohol septal ablation. METHODS: Hypertrophic obstructive cardiomyopathy patients aged ≥18 years (63 females and 71 males) who underwent alcohol septal ablation were included. The primary endpoint was all-cause mortality. RESULTS: The mean patient age was 60.0 (standard deviation 13.7) years. The median follow-up time was 13 (7.6-18.5) years. During the procedure, 9, 2, and 1 patients developed ventricular fibrillation, remote site myocardial infarction, and pericardial tamponade, respectively, but none died. One patient died during hospitalization. During the long-term follow-up, 17, 5, 20, and 8 patients developed heart failure, myocardial infarction, chronic atrial fibrillation, and non-fatal stroke, respectively, and 24 died. There was no significant difference between the sexes (all P > .05). Age (hazard ratio=0.69, 95% CI=0.61‒0.78, P < .001), body mass index (hazard ratio=1.20, 95% CI=1.04-1.40, P=.01), age at diagnosis (hazard ratio=1.57, 95% CI=1.34-1.78, P < .001), and time from diagnosis to ablation (hazard ratio=1.57, 95% CI=1.35-1.84, P< .001) predicted all-cause mortality. In Kaplan‒Meier curves, long-term all-cause mortality was similar in men and women (P[log-rank]=.43). CONCLUSION: Alcohol septal ablation has similar short- and long-term outcomes for both sexes in hypertrophic obstructive cardiomyopathy patients. Risk factors for longterm mortality were age, body mass index, diagnosis age, and time delay to operation. Therefore, alcohol septal ablation timing is essential for better clinical outcomes. Our findings may contribute to the increased performance of alcohol septal ablation in hypertrophic obstructive cardiomyopathy patients in our country.

Comparison of Sequential POT-Side-POT and Kissing Balloon Techniquesin Patientswith Coronary Bifurcation Lesions Treatedwith Single-Stent Strategy; Which One is Simple and Safe? Propensity Score Analysis.

BACKGROUND: It is unknown whether the novel POT-side-POT technique is more useful than the commonly preferred kissing balloon inflation in patients with non-complex coro- nary bifurcation lesions treated with a single-stent strategy. The aim of this study was to compare the efficacy of POT-side-POT and kissing balloon inflation techniques in one- stent strategy for non-complex coronary bifurcation lesions. METHODS: In this study, 283 patients were retrospectively analyzed (POT-side-POT group, n = 149; KBI group, n = 134). Primary endpoints of the study were defined as follows: in- hospital and 30-day mortality, contrast-induced acute kidney injury, stent thrombosis, side branch dissection, and need for side-branch stenting. Characteristics of patients at baseline were balanced by using propensity score inverse probability weighting. RESULTS: Procedure time (minute, 30.6 ± 8.5 vs. 34.3 ± 11.6; P = .003) and contrast volume (milliliter, 153.7 ± 42.4 vs. 171.1 ± 58.2; P = .004) were significantly lower in POT-side-POT group. Besides, side branch residual stenosis and number of patients with >50% side branch residual stenosis remained significantly higher in POT-side-POT group both in general and true bifurcation subgroup analysis (20.3 ± 19.8% vs. 16.5 ± 16.4%, P=.022; 11.9% vs. 5.7%, P = .013 and 24.1 ± 23.2% vs. 18.8 ± 18.7%, P = .033; 17.6% vs. 6.6%, P = .005; respectively). Combined clinical adverse outcomes were similar between groups. Side branch dissection (10.2% vs. 20.1%, P = .001) and need for side branch stenting (12.6% vs. 19%, P=.040) reached statistically significance in kissing balloon inflation group after adjustment. CONCLUSION: POT-side-POT may be a simple and safe technique with a shorter procedure time and lower incidence of adverse clinical events in non-complex coronary bifurcationlesions treated with single-stent strategy.

In-Hospital Bleeding in Elderly Patients With Acute Coronary Syndrome: Are Potent Antiplatelet Agents Safe?

Despite implementation of new interventional techniques and therapeutic advances, elderly patients with acute coronary syndrome (ACS) continue to be susceptible to in-hospital bleeding compared with younger ones. Thus, we investigated the incidence of in-hospital bleeding events and associated risk factors in elderly (≥ 75°years) ACS patients. We also wanted to define the bleeding sites, characteristics, and associated mortality. Bleeding Academic Research Consortium (BARC) classification type 2, 3, or 5 was used to define bleeding events. Overall, 539 patients were included in the study (mean age: 82.5 ± 4.8°years; 282 (52.3%) females). Of these patients, 69 (12.8%) developed in-hospital bleeding. Factors that were independently related with in-hospital bleeding were age (odds ratio (OR): 1.08; 95% confidence interval (CI): 1.011.14, P = .01), acute kidney injury (OR: 3.66; 95% CI: 2.016.69; P < .01), tirofiban (OR: 4.43; 95% CI: 1.7810.99; P < .01), and ticagrelor (OR: 1.93; 95% CI: 1.013.73; P = .04) administration. The urinary tract was the most frequent bleeding site, followed by femoral arteries. In conclusion, ticagrelor and tirofiban should be used with caution in elderly ACS patients.
