Serum total bilirubin level is associated with contrast induced nephropathy after primary percutaneous coronary intervention.

Contrast Induced Nephropathy (CIN) is a major complication of angiographic procedures. Primary percutaneous coronary intervention (pPCI) is the preferred treatment for ST-segment elevation myocardial infarction (STEMI) but is associated with a risk of CIN. Oxidative stress and free radical damage play a role in the pathogenesis of CIN. Bilirubin has anti-inflammatory and antioxidant activity and has been shown to have a protective effect on endothelial cells. The present study aimed to assess the association between serum bilirubin level and development of CIN after pPCI. Sequential STEMI patients (n = 595) who underwent pPCI between January 2021 and December 2022 were enrolled. Among the participants, 116 (19.5%) developed CIN. Serum total bilirubin level was significantly lower in the CIN group (P = .001). In multivariate logistic regression analysis, serum bilirubin level was found as an independent predictor of CIN. Age, gender, contrast volume, and white blood cell count were other independent predictors of CIN. A higher serum bilirubin level is associated with a lower risk of CIN in the present study. In STEMI patients undergoing pPCI, serum bilirubin level may be helpful to predict the risk of CIN and may help ensure early initiation of preventive treatment and careful follow-up.

Possible Clinical Benefits of Cardio-Ankle Vascular Index Measurement in Urological Diseases.

Many factors are considered to affect vascular physiology. It is known that one of the reasons for many diseases is a pathology at the microvascular level. Therefore, the relationship between endothelial dysfunction and many diseases is currently being investigated. The clinical evaluations of arterial stiffness have made it possible to perform necessary risk assessment regarding cardiovascular diseases. In this way, protective measures can be taken against microvascular pathologies in many organs. In this paper, we present a review of studies investigating the relationship between urological conditions and the cardio-ankle vascular index (CAVI), a marker of arterial stiffness. As with erectile dysfunction, some studies have shown that conditions such as lower urinary tract symptoms, overactive bladder, and chronic kidney disease are also associated with an elevated CAVI. The association of erectile dysfunction and chronic kidney disease with vascular pathologies has been clearly demonstrated. In addition, lower urinary tract symptoms may be the first sign of silent vascular dysfunction. Assessing arterial stiffness with CAVI can help prevent future cardiovascular events in these patients.

The predictive value of MAPH score for determining thrombus burden in patients with non-ST segment elevation myocardial infarction.

BACKGROUND: A high thrombus burden has been connected with poor clinical events in patients with non-ST segment elevation myocardial infarction (NSTEMI). In patients with STEMI, a high MAPH score has been associated with a large thrombus burden. However, the predictive value of the MAPH score in determining the thrombus burden in patients with NSTEMI is unclear. The present report aimed to evaluate the prognostic role of the MAPH score in the estimating coronary thrombus burden in NSTEMI patients. The study patients were split into two groups according to their thrombus grade. The low shear rate (LSR) and high shear rate (HSR) were estimated by haematocrit levels and serum total protein levels. The MAPH score was calculated by adding mean platelet volume (MPV) levels and age, in addition to total protein and haematocrit. RESULTS: The patients with a high thrombus burden (HTB) had a higher LSR, higher HSR and higher MAPH score compared to patients with low thrombus burden. MAPH score was found to be an independent predictors of HTB in Model 1 (OR: 1.124, 95% CI: 1.011-1.536; p = 0.039) and Model 2 (OR: 1.236; 95% CI: 1.002-1.525; p = 0.047). The cut-off value of the MAPH score for predicting HTB was 2 based on the Youden index. CONCLUSIONS: The MAPH score, which calculated by adding MPV levels and age, in addition to total protein and haematocrit, is a novel, easily accessible score. The MAPH score at both LSR and HSR was an independent predictor of HTB.

Prevalence of cardiac involvement in home-based recovered coronavirus disease 2019 (COVID-19) patients: a retrospective observational study.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has a risk of cardiac arrhythmia, acute coronary syndrome, heart failure and myocarditis, and the prognosis of COVID-19 has been associated with cardiovascular symptoms. However, there has not been enough information about cardiovascular involvement in patients who had recovered home-based mild symptoms of COVID-19 infection. Therefore, this study evaluates the prevalence of cardiac involvement and associated factors in home-based recovered COVID-19 patients. SUBJECT AND METHODS: A total of 64 participants who applied to cardiology outpatient clinics with cardiac symptoms after recovering from COVID infection were recorded between April and December 2020. The patients were divided into two according to cardiovascular involvement in the cardiovascular magnetic resonance (CMR) imaging results. RESULTS: No significant difference between the two groups regarding age and co-morbidities. Patients with cardiac involvement had higher C-reactive protein compared to without cardiac involvement patients. A total of 46 patients who recently recovered from COVID-19 had abnormal CMR findings such as myocardial late gadolinium enhancement or pericardial enhancement. In addition, the left ventricular ejection fraction and stroke volume were significantly lower in the cardiac involvement patients. CONCLUSION: We demonstrate cardiac involvement in 46 patients (71%) with recent COVID-19, independent of pre-existing conditions. This indicates that there may be widespread cardiac involvement without high troponin values or severe clinical symptoms.
