Abstract

Background: Currently available risk stratification models for acute pulmonary embolism (PE) include hemodynamic status, cardiac biomarkers, right ventricle (RV) dysfunction on imaging, and clinical scores. Focusing on the length--tension relationship of the ventricle might have a superior predictive capability over RV dysfunction in terms of mortality and classification of patients with acute PE. In this study, our hypothesis suggests that the tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary artery pressure (sPAP) ratio has superior predictive capability for in-hospital mortality in patients with acute PE compared to TAPSE or sPAP as distinct measures. Methods: This single-center study comprised retrospectively evaluated 703 patients referred to our tertiary cardiovascular center with acute PE. We divided patients into quartiles based on the TAPSE/sPAP ratio. Different models were developed to quantify the predictive relationship between in-hospital death and echocardiographic measurements. A base model was created with variables including risk status and RV/LV ratio >1. Then, to evaluate the predictive contribution of each measurement; TAPSE/sPAP, TAPSE, and sPAP were sequentially added to the base model. After that, the performance of each model was evaluated. Results: Predictive and discriminative power was the highest in model containing TAPSE/ sPAP. There was still a significant inverse association between TAPSE/sPAP and the risk of in-hospital death even after adjusting for risk status and RV/LV ratio >1. Receiver operating characteristic curve analysis for TAPSE/sPAP revealed the best cut-off value as 0.34. Conclusion: The outcomes of our study reveal that the ratio of TAPSE/sPAP serves as a more potent predictor of mortality than either of the 2 measurements taken separately. The interpretation and utilization of the TAPSE/sPAP cut-off value in acute PE can assist in identifying patients at risk of deterioration and guide the consideration of more intensive treatment options across all risk groups.

Abstract

Background: In this study, we aimed to investigate the clinical follow-up results of endoscopic thoracic sympathectomy (ETS) in the treatment of vasospastic angina (VSA) resistant to maximal medical therapy. Methods: A total of 80 patients with VSA who presented to our hospital between 2010 and 2022 were included in our study. Among them, 6 patients who did not respond to medical therapy underwent ETS. In-hospital and long-term clinical outcomes of patients who underwent ETS were recorded. Results: The median age of the patients with VSA was 57 [48-66] years, and 70% of the group were males. In the ETS group, compared to the non-ETS group, higher numbers of hospital admissions and coronary angiographies were observed before ETS (median 6 [5-6] versus 2 [1-3], P < .001; median 5 [3-6] versus 2 [1-3], P = .004, respectively). Additionally, while 2 patients (33.3%) in the ETS group had implantable cardioverter defibrillator (ICD), only 2 patients (2.7%) in the non-ETS group had ICD (P = .027). Out of the 6 patients who underwent ETS, 2 were females, with a median age of 56 [45-63] years. Four patients underwent successful bilateral ETS, while 2 patients underwent unilateral ETS. During the follow-up period after ETS, only 3 patients experienced sporadic attacks (once in 28 months, twice in 41 months, and once in 9 years, respectively), while no attacks were observed in 3 patients during their median follow-up of 7 years. Conclusion: It appears that ETS is effective in preventing VSA attacks without any major complications. [ABSTRACT FROM AUTHOR]

Abstract

The Naples score is a new prognostic score developed according to inflammatory and nutritional status and frequently evaluated in cancer patients. The present study aimed to evaluate using the Naples prognostic score (NPS) to predict the development of decreased left ventricular ejection fraction (LVEF) after acute ST-segment elevation myocardial infarction (STEMI). The study has a multicenter and retrospective design and included 2280 patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) between 2017 and 2022. All participants were divided into 2 groups according to their NPS. The relationship between these 2 groups and LVEF was evaluated. The low-Naples risk group (Group-1) included 799 patients, and the high-Naples risk group (Group-2) had 1481 patients. Hospital mortality, shock, and no-reflow rates were found to be higher in Group 2 compared with Group 1 (P <.001, P =.032, P =.004). The NPS was significantly inversely associated with discharge LVEF (B coefficient: −1.51, 95% CI-2.26; −.76, P =.001). NPS, a simple and easily calculated risk score, may help identify high-risk STEMI patients. To the best of our knowledge, the present study is the first to demonstrate the relationship between low LVEF and NPS in patients with STEMI. [ABSTRACT FROM AUTHOR]

Abstract

It was investigated that whether or not hypertensive patients with controlled blood pressure (BP) and blunted nighttime BP fall show attenuated heart rate (HR) recovery after exercise. All subjects underwent a maximal exercise testing according to Bruce protocol. The heart rate recovery (HRR) was defined as the difference in HR between the end of the exercise and 1 minute after exercise. 24-h ambulatory BP monitoring determined the circadian BP pattern. Patients with dipper BP status had lower average nighttime systolic-diastolic BP values; and higher values of percentage of systolic-diastolic BP reduction compared to non-dippers. Dippers had also higher HRR values than nondippers (34.36±14.55/min-32.48±8.60/min, p=0.025). There were no correlation between HRR and average nighttime systolic-diastolic BP and percentage of systolic-diastolic BP reduction. To sum up there is statistically significant but not clinically so important association between non-dipper phenomenon and a slowed HRR. This may demonstrate the importance of BP control rather than correcting the nondipper condition., Kan basıncı (KB) kontrollü olan ve gece ölçülen kan basıncında yeterli düşme olmayan (non-dipper) hipertansiflerin egzersiz testi sonrası kalp hızı toparlanmasında gecikme gösterip göstermediği incelendi. Tüm hastalara Bruce protokolüne göre maksimal efor testi uygulandı. Kalp hızı toparlanması (KHT), efor testi bittiğindeki kalp hızı ile bir dakika sonraki kalp hızı arasındaki fark olarak tanımlandı. Sirkadiyen KB, 24 saatlik ambultuvar KB monitörizasyonu ile tespit edildi. Dipper KB profili olan hastaların “non-dipper” olanlara göre gece ortalama sistolik ve diyastolik KB daha düşük, sistolik ve diyastolik KB gece gündüz farkı yüzdesi ise daha yüksekti. Dipper olanların KHT değerleri “non-dipper” bireylerden daha yüksekti (34.36±14.55/dak-32.48±8.60/dak, p=0.025). Ortalama gece sistolik-diyastolik KB değerleri ve KB gece gündüz farkı yüzdesi ile KHT arasında korelasyon yoktu. Sonuç olarak “Non-dipper” durum ile KHT gecikmesi arasında istatistiksel olarak anlamlı ancak klinik açıdan çok da önemli olmayan bir ilişki vardır. Bu bulgular “non-dipper” durumun düzeltilmesinden çok KB kontrolünün önemini gösterebilir.

Abstract

Amaç: Çok sayıda aterosklerotik risk faktörünü bir arada barındıran metabolik sendrom (MS), oksidatif stresin ve kardiyovasküler mortalitenin arttığı bir hastalıktır. Karaciğerde sentezlenen ve plazmada yüksek dansiteli lipoprotein kolesterol (HDL-K) üzerinde taşınan paraoksonaz 1 (PON1) enzimi, düşük dansiteli lipoprotein kolesterolün (LDL-K) oksidasyonunu engelleyerek ateroskleroza karşı koruyucu etki göstermektedir. Bu çalışmanın amacı; koroner arter hastalığı (KAH) olan ve olmayan metabolik sendromlu hastalarda paraoksonaz 1 enzim aktivitelerini karşılaştırmak, ayrıca KAH olan MS olgularında Gensini skoru ile değerlendirilen KAH yaygınlığı ile PON1 aktivitesi arasındaki ilişkiyi incelemektir.Gereç ve Yöntem: Çalışmaya Uludağ Üniversitesi Tıp Fakültesi Kardiyoloji Anabilim Dalı Hemodinami Laboratuvarında koroner anjiyografileri yapılan toplam 80 hasta alındı. Hastalar 3 gruba ayrıldı. `Adult Treatment Panel III' (ATP III) 2001 kriterlerine göre MS tanısı konan ve koroner anjiyografide sol ön inen, sirkumfleks, sağ koroner arter ya da bunların ana dallarında, lümeni ?%50 daraltan aterosklerotik lezyon olan 30 hasta grup 1'i (MS+ KAH+) oluşturdu. MS olup koroner arterlerinde darlık saptanmayan 30 hasta grup 2 (MS+ KAH-), MS kriterlerini karşılamayan ve koroner arterlerinde darlık olmayan 20 hasta grup 3 (kontrol grubu, MS- KAH-) olarak sınıflandırıldı. Gruplar PON1 aktiviteleri açısından karşılaştırıldı. MS ve KAH olan olgularda (grup 1), KAH yaygınlığı ve ciddiyeti Gensini skoru kullanılarak belirlendi ve bu grupta KAH yaygınlığı ile PON1 aktivitesi arasındaki ilişki değerlendirildi.Bulgular: PON1 enzim aktivitesi MS+ KAH- olan grupta, kontrol grubundan daha düşüktü (p=0,004). MS+ KAH+ olan grupta hem kontrol grubundan (p
