RESUMO

BACKGROUND: Optimal first-trimester anticoagulation is still challenging in pregnant women with mechanical heart valves (MHVs) requiring high-dose warfarin. This multicenter prospective study aims to determine the optimal anticoagulation regimens for pregnant patients with MHVs. METHODS: All women were allocated to one of three treatment options during first trimester including lone low-molecular-weight heparin (LMWH), combination of LMWH + 2.5 mg warfarin, and LMWH+4 mg warfarin. Primary maternal outcome included a combination of death, thromboembolism, severe bleeding, and need for treatment of mechanical valve thrombosis (MVT). Any fetal loss was determined as primary fetal outcome. RESULTS: The study included 78 pregnancies in 65 women with MHVs. Primary maternal outcome rate was 44%, 12.5%, 3.5%, respectively. The rates of primary maternal outcome (44 vs 3.5%, P < .001), obstructive MVT (16 vs 0%, P = .04), MVT requiring treatment (28 vs 0%, P = .003), and cerebral embolism (24 vs 3.4%, P = .041) were found to be significantly higher in lone LMWH group compared to LMWH + 4 mg warfarin group. Moreover, the rates of primary maternal outcome (12.5 vs 44%, P = .015) and treatment for MHV thrombus (4.2 vs 28%, P = .049) were significantly lower in LMWH + 2.5 mg warfarin group compared to lone LMWH group. The incidences of fetal loss were 8 (32%) in the lone LMWH group, 8 (33.3%) in LMWH + 2.5 mg warfarin group, and 11 (37.9%) in LMWH + 4 mg warfarin group (P = .890 for 3-group).Warfarin related-embryopathy was not observed in any case. CONCLUSIONS: The combined anticoagulation strategy of LMWH plus low-dose warfarin during the first trimester of pregnancy may result in less maternal complications with comparable fetal outcomes in patients with MHVs. CONDENSED ABSTRACT: Low-molecular-weight heparin (LMWH) is thought to be safer for the fetus, however it is suspected to be less protective for the mother. To solve this dilemma, the authors suggested a novel anticoagulation strategy in pregnant women with prosthetic valves. Seventy-eight pregnancies of 65 women (median age 32 [27-35] years) were included in the study. A combination of LMWH and a reduced dose warfarin were associated with low rates of thrombus-related complications in pregnant patients with mechanical heart valves.

RESUMO

INTRODUCTION AND OBJECTIVE: Despite major advances in reperfusion therapies, morbidity and mortality rates associated with cardiovascular disorders remain high, particularly in patients with ST-segment elevation myocardial infarction (STEMI). Therefore, identifying prognostic variables that can be used to predict morbidity and mortality in STEMI patients is critical for better disease management. The HALP (hemoglobin, albumin, lymphocyte, and platelet) score, a novel index indicating nutritional status and systemic inflammation, provides information about prognosis. In this context, this study was carried out to investigate the relationship between HALP score assessed at admission and in-hospital mortality in STEMI patients. MATERIAL AND METHODS: The population of this retrospective study consisted of 1307 consecutive patients diagnosed with STEMI and who underwent primary percutaneous coronary intervention (pPCI). The 1090 patients included in the study sample were divided into two groups based on the median HALP score value of 3.59. In-hospital and all-cause mortality rates during the follow-up were obtained from the registry. RESULTS: In-hospital mortality rate was significantly higher in patients with a HALP score of less than 3.59 compared to those with a HALP score of more than 3.59 (7.5% and 0.7%, respectively; P < 0.001). Univariate and multivariate Cox proportional hazard analyses revealed that the HALP score is independently associated with in-hospital mortality. The optimal HALP score cutoff value of <3.72 predicted in-hospital mortality with 95.56% sensitivity and 49.19% specificity. CONCLUSION: This study's findings indicate that HALP score may be a significant independent predictor of in-hospital mortality in patients with STEMI treated with pPCI.

RESUMO

BACKGROUND: Silent cerebral infarction (SCI) is a neuronal injury without a clinically apparent stroke or transient ischaemic attack. Left atrial cardiomyopathy is closely associated with SCI. P wave changes in the electrocardiogram (ECG) provide significant information about the development of atrial cardiomyopathy. This study evaluated the role of P wave parameters and indices and a novel ECG parameter in predicting SCI, future cerebrovascular events, and atrial fibrillation/flutter. MATERIALS AND METHODS: A total of 272 patients were retrospectively screened and divided into two groups according to SCI. Cerebrovascular events and atrial fibrillation/flutter were defined as the study's outcomes. P wave parameters, indices, and a novel ECG parameter called the P wave ratio (PWR) were calculated from ECGs, and the relationship between SCI and outcomes was investigated. RESULTS: The maximum P wave duration (PWD), P wave dispersion (PWdisp), PWD measured from the D2 lead (PWDD2), P wave peak time measured from the D2 lead (PWPTD2), PWPT measured from the V1 lead (PWPTV1), and P wave terminal force (PWTFV1) were significantly longer in the SCI group. Both partial and advanced inter atrial block (IAB) were significantly high in the SCI group. The novel parameter P wave ratio (PWR) was significantly longer in the SCI group (0.55 ± 0.08 vs. 0.46 ± 0.09; p < 0.001). In multivariate regression analysis, PWdisp (OR: 1.101, p < 0.001), PWPTD2 (OR: 1.095, p = 0.017), and PWR (OR: 1.231, p < 0.001) were found to be independent predictors of SCI. Cox regression analysis revealed that the PWR (HR 1.077; 95% CI 1.029-1.128; p = 0.001) was associated with cerebrovascular events and atrial fibrillation/flutter. CONCLUSION: In our study, we observed that PWR could be a valuable parameter for predicting SCI and future cerebrovascular events.

RESUMO

The purpose of this investigation was to investigate whether there was an association between the Naples prognostic score and the development of acute kidney injury (AKI) in ST-elevation myocardial infarction (STEMI) patients following primary percutaneous coronary intervention (pPCI). The study comprised 2901 consecutive STEMI patients who had pPCI. For each patient, the Naples prognostic score was determined. To evaluate the predictive performance of the Naples score (which included either continuous and categorical variables), we developed a Nested model and a nested model combined with the Naples score. The Naples prognostic score was the most significant predictor of AKI occurrence after admission creatinine, age, and contrast volume. The continuous Naples prognostic score model provided the best prediction performance and discriminative ability. The C-index of the Nested and full models with continuous Naples prognostic score were significantly higher than that of the Nested model. The decision curve analysis found that the overall model had a higher full range of probability of clinical net benefit than the baseline model, with a 10% AKI likelihood. The present study found that the Naples prognostic score may be useful to predict the risk of AKI in STEMI patients undergoing pPCI.

RESUMO

BACKGROUND: Intermittent malfunction is a rare but potentially serious complication of prosthetic heart valve replacement. This study aimed to describe the clinical features and etiologic causes of patients with intermittent mechanical prosthetic heart valve dysfunction. METHODS: Between 2010 and 2021, 16 patients who were evaluated in the echocardiography laboratory of Kosuyolu Training and Research Hospital with the diagnosis of intermittent malfunction of prosthetic valves were included in the study. RESULTS: The evaluated patients consisted of 12 bi-leaflet mitral valve replacements and 2 mono-leaflet mitral valve replacements. The underlying causes of intermittent malfunction were classified as follows: residual chord (n=4), obstructive thrombus (n=2), non-obstructive thrombus (n=2), vegetation (n=2), pannus and obstructive thrombus coexistence (n=1), and solely pannus (n=1). One of the patients with mono-leaflet mitral valve replacements had pannus and obstructive thrombus. In the other patient with mono-leaflet mitral valve replacement, a stuck valve was observed in 1 of 12 beats secondary to arrhythmia. There were also 2 patients with aortic valve replacements. One patient had moderate aortic regurgitation due to prominent calcification and the other had moderate obstruction due to pannus. In the patient with pannus, a stuck leaflet was observed in 1 of 6 beats and moderate aortic regurgitation arose in 1 of 2 beats in the patient with calcification. CONCLUSIONS: The intermittent stuck valve may have catastrophic outcomes. When making a treatment decision in these patients, assessing the degree of regurgitation or stenosis is essential. In particular, the frequency of entrapment should be taken into consideration when deciding the optimal therapy for intermittent prosthetic heart valve dysfunction.

RESUMO

BACKGROUND: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery. OBJECTIVES: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT. METHODS: A total of 158 obstructive PVT patients (women: 103 [65.2%]; median age 49 years [IQR: 39-60 years]) were enrolled in this multicenter observational prospective study. TT was performed using slow (6 hours) and/or ultraslow (25 hours) infusion of low-dose tissue plasminogen activator (t-PA) (25 mg) mostly in repeated sessions. The primary endpoint of the study was 3-month mortality following TT or surgery. RESULTS: The initial management strategy was TT in 83 (52.5%) patients and surgery in 75 (47.5%) cases. The success rate of TT was 90.4% with a median t-PA dose of 59 mg (IQR: 37.5-100 mg). The incidences of outcomes in surgery and TT groups were as follows: minor complications (29 [38.7%] and 7 [8.4%], respectively), major complications (31 [41.3%] and 5 [6%], respectively), and the 3-month mortality rate (14 [18.7%] and 2 [2.4%], respectively). CONCLUSIONS: Low-dose and slow/ultraslow infusion of t-PA were associated with low complications and mortality and high success rates and should be considered as a viable treatment in patients with obstructive PVT.

RESUMO

It was previously observed that two dimensional (2D) Doppler derived and real-time three-dimensional (RT-3D) directly measured valve areas were smaller than reported manufacturer sizes. It may be helpful to obtain the ranges of inner diameters (IDs) and the geometric orifice area (GOA) during evaluation of prosthetic mitral valves. In this study, we aimed to provide reference dimensional parameters of bileflet mitral mechanical prosthetic valves. Patients with recent mitral valve replacement were examined by 2D and RT-3D transesophageal echocardiography (TEE) in the early postoperative period when the presence of pannus overgrowth was unlikely. Measurements of 2D IDs, 3D hinge to hinge (HHD) and edge to edge diameters (EED) and 3D GOA were obtained and compared with reported manufacturer sizes and areas. This study enrolled 126 patients with mitral prosthetic valves (38 ATS, 42 Carbomedics, 46 St. Jude Medical, all bileaflet). The measured 2D and 3D IDs and GOA were significantly smaller than reported manufacturer sizes in the majority of the valve sizes. This RT-3D TEE-guided study provides ranges of reference values for directly measured IDs and GOA of the three most commonly used mechanical mitral prosthetic valve types for the first time in a relatively large series.

RESUMO

OBJECTIVE: Prosthetic valve thrombosis (PVT) is a serious complication among patients with prosthetic heart valves. Thrombolytic therapy (TT) is now widely used as first-line treatment for PVT. Endothelial dysfunction has previously been reported in patients with PVT. The aim of this study was to investigate the changes in endothelial function soon after TT in PVT patients. METHODS: The study group included 85 patients with PVT [female: 53 (62.3%); age: 48.7±13.9 years] who were evaluated prospectively before and shortly after TT. All of the patients were evaluated using transthoracic and transesophageal echocardiography. TT was administered in all cases with a low-dose, ultra-slow infusion regimen. Endothelial function was evaluated using a noninvasive measurement of flow-mediated dilatation (FMD) of the brachial artery during reactive hyperemia. RESULTS: The study population included 38 (44.7%) obstructive and 47 (55.3%) non-obstructive PVT patients. The obstructive PVT patients had lower baseline FMD values than the non-obstructive PVT group (5.31±0.76% vs. 5.87±0.84%; p=0.003). TT was successful in 79 patients (92.9%). FMD was significantly increased in the successfully thrombolyzed patients after TT (5.65±0.86% vs. 7.13±1.26%; p<0.001). There was no significant difference in the FMD values after TT in patients who were unresponsive to TT (5.07±0.61% vs. 5.38±0.95%; p=0.371). There was a significant increase in FMD values after TT in patients with obstructive PVT (5.31±0.76% vs. 8.22±1.15%; p<0.001). However, this difference was not statistically significant for patients with non-obstructive PVT (5.87±0.84% vs. 6.11±0.95%; p=0.276). CONCLUSION: This study demonstrated that successful TT may contribute to improvement of impaired endothelial function in patients with obstructive PVT.

RESUMO

: We aimed to investigate how prosthetic valve thrombosis (PVT) affects brain natriuretic peptide (BNP) levels and how BNP changes following thrombolytic therapy. The study included 70 consecutive patients with left-sided mechanical PVT who received thrombolytic therapy. The patients were divided into two groups, namely obstructive thrombus (n = 42) and nonobstructive thrombus (NOT, n = 28). BNP levels of patients were assessed before and after thrombolytic therapy. BNP levels were higher in obstructive thrombus group than NOT group in whole study population, in patients with mitral PVT and in patients with aortic PVT [325.0 (189.5-496.0) vs. 84.0 (44.5-140.0), P < 0.001, 323.0 (193-449.0) vs. 59.0 (37.0-131.0), P < 0.001 and 321.0 (132.0-525.0) vs. 99.0 (60.5-173.0), P < 0.001]. BNP levels were positively correlated with transmitral and transaortic mean gradients, and negatively correlated with mitral valve area (r: 0.374, P = 0.013; r: 0.432, P = 0.035 and; r: -0.642, P < 0.001, respectively). BNP values above 165 pg/ml may predict the presence of obstructive thrombus with a sensitivity of 88.0%, and a specificity of 79.0% (AUC = 0.928, 95% confidence interval: 0.871-0.986, P < 0.001). Following thrombolytic therapy, BNP levels (pg/ml) significantly decreased from 325.0 (189.5-496.0) to 137.0 (101.7-224.5), P < 0.001, in all patients with obstructive thrombus, from 323.0 (193.0-449.0) to 129.0 (98.0-223.0), P < 0.001, in patients with only mitral obstructive thrombus and from 321.0 (132.0-525.0) to 181.0 (99.0-217.5), P < 0.001, in patients with only aortic obstructive thrombus. BNP levels are significantly higher in prosthetic valve patients with obstructive thrombus than in those with NOT and decrease in patients with obstructive thrombus after thrombolytic therapy. A cut off value of BNP of at least 165.0 pg/ml was found to discriminate obstructive thrombus from NOT.

RESUMO

Mechanical prosthetic heart valves (MPHVs) are highly thrombogenic, and a pregnancy-induced procoagulant status increases the risk of MPHV thrombosis. Despite numerous case reports, 2 major registries and meta-analyses/systematic reviews, optimal anticoagulation therapy during pregnancy remains controversial. The goal of this study was to evaluate different anticoagulation regimens in pregnant patients with MPHVs. The outcomes of anticoagulation regimens were assessed retrospectively in pregnant women (110 women; 155 pregnancies) with MPHVs. The study population was divided into 5 groups according to anticoagulation regimens used; high-dose warfarin (>5 mg/d) throughout pregnancy (group 1), low-dose warfarin (≤5 mg/d) throughout pregnancy (group 2), low molecular weight heparin (LMWH) throughout pregnancy (group 3), first trimester LMWH, 2nd and 3rd trimester warfarin (group 4), first 2 trimester LMWH, and 3rd trimester warfarin (group 5). Of 155 pregnancies, 55 (35%) resulted in fetal loss; whereas 41 (27%) cases with abortion (miscarriage and therapeutic) and 14 (9%) stillbirths occurred. The comparison of the groups showed that the whole abortion rates including therapeutic abortion were significantly higher in Group 1, and lower in groups 3 and 5 (p <0.001). However, miscarriage rates were similar between the groups. A total of 53 pregnancies (34%) suffered from prosthetic valves thrombosis (PVT) during pregnancy or in the postpartum period. Group 2 had significantly lower rates of PVT than the other groups (p <0.001). In conclusion, the current data suggests that there is no optimal therapy, and that all managements have advantages and disadvantages. Low-dose warfarin (≤5 mg/day) regimen with therapeutic international normalized ratio levels may provide effective maternal protection throughout pregnancy with acceptable fetal outcomes.

RESUMO

OBJECTIVE: Spontaneous echo contrast (SEC) is defined as dynamic, smoke-like echoes within the cardiac cavities with a characteristic swirling motion seen on echocardiography. Clinical studies have demonstrated that SEC is a risk factor for left atrial thrombus formation and an important indicator for potential systemic embolism. Platelet indices have been associated with the presence of SEC in patients with mitral stenosis. The aim of this study was to investigate the relationship between platelet indices and SEC in patients with prosthetic heart valves. METHODS: A total of 89 patients [female: 38 (42.4%); median age: 52 years (range: 36-67 years)] with SEC formation in the left atrium, and 257 control subjects [female: 123 (47.5%); median age: 56 years (range: 45-65 years)] without SEC formation were enrolled. All of the patients were evaluated by using transthoracic and transesophageal echocardiography. Laboratory tests including complete blood count and biochemical parameters were analyzed. RESULTS: Patients with SEC formation had more frequent atrial fibrillation, higher left atrial diameter (LAD) and lower left ventriular ejection fraction values. Platelet indices including platelet count, platelet distribution width, mean platelet volume, and plateletcrit did not differ between the groups. Increased LAD was detected as the only independent predictor of SEC development. CONCLUSION: Platelet indices were not found to be associated with the presence of SEC formation in the left atrium among patients with mitral prosthetic valves. Therefore, the use of platelet indices alongside known echocardiographic and clinical risk factors to predict SEC development in patients with a mitral prosthesis is debatable.

RESUMO

OBJECTIVE: Normal reference values for the cardiac chambers are widely based on cohorts from European or American populations. In this study, we aimed to obtain normal echocardiographic measurements of healthy Turkish volunteers to reveal the age, gender, and geographical region dependent differences between Turkish populations and other populations. METHODS: Among 31 collaborating institutions from all regions of Turkey, 1154 healthy volunteers were enrolled in this study. Predefined protocols were used for all participants during echocardiographic examination. Blood biochemical parameters were also obtained for all patients on admission. The American Society of Echocardiography and European Association of Cardiovascular Imaging recommendations were used to assess the echocardiographic cardiac chamber quantification. RESULTS: The study included 1154 volunteers (men: 609; women: 545), with a mean age of 33.5±11 years. Compared to men, women had a smaller body surface area, lower blood pressure and heart rate, lower hemoglobin, total cholesterol, lower low-density lipoprotein (LDL) levels, and higher high density lipoprotein (HDL) levels. Cardiac chambers were also smaller in women and their size varied with age. When we compared the regions in Turkey, the lowest values of left cardiac chamber indices were seen in the Marmara region and the highest values were observed in the Mediterranean region. Regarding the right cardiac indices, the Mediterranean region reported the lowest values, while the Black Sea region and the Eastern Anatolia region reported the highest values. CONCLUSION: This is the first study that evaluates the normal echocardiographic reference values for a healthy Turkish population. These results may provide important reference values that could be useful in routine clinical practice as well as in further clinical trials. (.

RESUMO

The past 65 years have witnessed remarkable progress in the development of safe, hemodynamically favorable mechanical heart valves. Today, there are a large number and variety of prostheses in use and many prostheses have been used for a while and then discontinued. When patients lack reliable information about their heart valve prostheses, identification of valve model becomes difficult even for specialized physicians in this area. A combination of cinefluoroscopy and echocardiography makes it possible to provide accurate and detailed information regarding identification of prosthetic valve models. Fluoroscopic examination is a useful technique to evaluate patients following mechanical heart valve replacement. However, transthoracic echocardiography and transesophageal echocardiography have almost replaced cinefluoroscopy in the evaluation of prosthetic heart valves. Especially, real-time three-dimensional transesophageal echocardiography provides distinctive images of prosthetic heart valves, particularly for those in the mitral position. A large body of literature has been published to familiarize physicians with the radiological appearance of numerous mechanical prostheses. However, there is a lack of data regarding the identification of prosthetic valve models based on echocardiographic appearance. In this review, we aimed to describe distinctive echocardiographic and cinefluoroscopic markers for identifying the type and brand of several commonly used mechanical prosthetic heart valves.

RESUMO

BACKGROUND: The relationship between severity of coronary artery disease and inflammatory parameters has been previously demonstrated. However, there is a lack of data regarding the role of C-reactive protein-to-albumin ratio (CAR) in slow coronary flow (SCF) in patients with stable angina pectoris (SAP). In this study, we aimed to investigate the relationship between CAR and presence of SCF in patients with SAP. PATIENTS AND METHODS: This study enrolled 217 patients undergoing coronary angiography for SAP. SCF was detected in 81 (37.3%) patients, and the control group included 136 patients. All clinical, demographical, and laboratory parameters were entered into a dataset and compared between SCF group and the controls. RESULTS: The mean age of the patients was 66.1 ± 12.1 years (male: 57.1%). C-reactive protein and CAR were significantly higher in patients with SCF compared with controls (P = 0.004 and < 0.001, respectively). Logistic regression analysis demonstrated that high CAR level was an independent determinant of SCF (odds ratio: 1.023; 95% confidence interval: 1.013-1.034; P < 0.001). CONCLUSION: Higher CAR level may be a valuable predictor of SCF in patients with SAP who undergo coronary angiography. Inflammation may play an important role in the pathogenesis of SCF.

RESUMO

INTRODUCTION: Stent restenosis remains a clinical challenge for patients with ischemic heart disease, since it is associated with repeated coronary interventions as well as higher hospitalization rates and medical costs. Inflammation plays a significant role. Although an association between stent restenosis, increased C-reactive protein (CRP) and decreased albumin levels has been previously reported, no studies have investigated the ability of the CRP/albumin ratio to predict stent restenosis. METHODS: This retrospective study included 448 patients who had previously undergone primary percutaneous coronary intervention and who were referred for subsequent reintervention due to recurrence of anginal symptoms. The study population was divided into two groups based on whether the patient had developed stent restenosis. They were then stratified into three groups according to their CRP/albumin ratio. RESULTS: Out of 448 patients, stent restenosis was observed in 24.5% (n=110), as determined by coronary angiography. Patients with stent restenosis had a higher CRP/albumin ratio, greater platelet distribution width (PDW), higher CRP levels, and lower levels of both high-density lipoprotein (HDL) cholesterol and serum albumin. The CRP/albumin ratio (OR: 2.289, 95% CI: 1.056-4.959; p=0.036), stent diameter, PDW and HDL cholesterol levels were found to be independent predictors of stent restenosis. A ROC curve comparison demonstrated that the CRP/albumin ratio was a better predictor of restenosis than either albumin and CRP individually, but it was not better than PDW and HDL cholesterol. CONCLUSION: As a novel inflammation-based risk score, the CRP/albumin ratio may be an easily accessible marker for assessment of stent restenosis risk.

RESUMO

INTRODUCTION: Cardiac myxomas are the most common primary intracardiac tumors. Although myxomas are histologically benign, they are potentially dangerous due to potential risk of systemic and cerebral embolism. In this study, we aimed to investigate the potential predictors of embolism in patients with left atrial myxoma. METHODS: This single-center retrospective study enrolled 93 patients (mean age: 52.9 ± 15.3 years, female: 70 [75.3%]) with left atrial myxomas between 2014 and 2018. The patients were classified into two groups (embolic vs nonembolic) to investigate possible predictors of embolism. Demographic, laboratory, and echocardiographic parameters were recorded into a dataset and compared between patients with and without embolism. RESULTS: The study population was composed of 13 (14%) patients in embolic (11 cerebrovascular and 2 peripheral) and 80 (86%) patients in nonembolic group. Demographic and laboratory parameters were similar between the groups. Tumor sizes were significantly higher in the embolic group than in the nonembolic group (5.59 ± 1.08 vs 4.29 ± 0.61; P = 0.001). By multivariate analysis, increased tumor size, increased left atrial diameter, and the presence of atrial fibrillation and irregular tumor surface were identified as independent predictors of embolism. In ROC curve analyses, tumor size above 4.6 cm predicted embolism with a sensitivity of 77% and a specificity of 73% (AUC: 0.858; 95% CI: 0.752-0.964; P < 0.001). CONCLUSION: The presence of atrial fibrillation, irregular tumor surface, increased tumor size, and increased left atrial diameter is associated with increased risk of embolism in patients with left atrial myxoma. Early surgery should be scheduled for such patients due to increased potential for embolism.

RESUMO

BACKGROUND: The aim of this study was to evaluate the usefulness of the Syntax Score II (SSII) in predicting in-hospital and long-term mortality in octogenarians who presented with ST-segment elevation myocardial infarction (STEMI) and were treated with primary percutaneous coronary intervention (pPCI) in addition to compare SS II with other risk-scoring systems. METHODS: We retrospectively enrolled 312 consecutive STEMI patients in the eighth decade of life or older who underwent pPCI. The octogenarians were divided into two groups according to their median SSII (low SSII ≤ 43.6 and high SSII > 43.6), and these groups were compared in terms of mortality. The performance of the SSII in predicting patients' outcomes was further compared with that of other well-known risk-scoring systems. RESULTS: In the study, the SSII was an independent predictor of long-term mortality (OR: 1.036 95% CI: 1.005-1.068; p = 0.024). Both in-hospital (20.8% vs. 1.2%; p < 0.001) and long-term mortality (45.0% vs. 11%; p < 0.001) were higher among the patients with a high SSII compared to those with a low SSII. An ROC curve comparison showed that SSII was a better predictor (AUC: 0.807; 95% CI: 0.750-0.863) of long-term mortality than SS, PAMI, TIMI, and GRACE risk scores but not CADILLAC. CONCLUSIONS: Based on the study findings, octogenarians with a high SSII had worse in-hospital and long-term survival. The SSII, which includes several clinical and anatomical parameters, may be a better predictor of mortality than other risk-scoring systems in octogenarians.
