Toluene Inhalant Addiction and Cardiac Functions in Young Adults: A Comparison of Electrocardiographic and Echocardiographic Parameters.

Background: Volatile substance (thinner) addiction can cause serious cardiac events, such as malignant ventricular arrhythmias, acute coronary syndromes, sudden death syndrome, and dilated cardiomyopathy, as reported in many case studies. We aimed to find echocardiographic and electrocardiographic parameters that could foresee these adverse outcomes in clinical settings.

Methods: We enrolled 32 healthy young adult patients with at least 1 year of thinner addiction and no cardiac symptoms.

Exploring Variations in Etiology and Clinical Presentations of Kounis Syndrome Across Pediatric and Adult Populations: A Comprehensive Review.

Kounis syndrome (KS), recognized as a rare yet significant form of acute coronary syndrome precipitated by allergy-mediated mechanisms, poses diagnostic challenges due to its varied clinical presentations and under-recognition. Despite its relevance across diverse populations, comprehensive insights into age-specific characteristics and management remain limited. The analysis of 420 studies yielded a total of 466 case reports of Kounis syndrome, categorized into pediatric (n = 31) and adult (n = 435) populations.

Mean Platelet Volume and Its Association With In-Hospital Outcomes in Patients With Acute ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

Background Mean platelet volume (MPV), reflecting platelet size and activation, has been associated with cardiovascular disease (CVD) risk and mortality. Yet, its prognostic significance in acute coronary syndrome (ACS) patients undergoing primary percutaneous coronary intervention (PCI) remains uncertain. This study investigates whether elevated MPV levels upon admission in ST-segment elevation myocardial infarction (STEMI) patients predict adverse in-hospital outcomes after primary PCI.

The Impact of the Neutrophil-to-Lymphocyte Ratio on In-Hospital Outcomes in Patients With Acute ST-Segment Elevation Myocardial Infarction.

Introduction The neutrophil-to-lymphocyte ratio (NLR) is a significant predictor of cardiovascular diseases, influencing their progression and prognosis. The exact role of the NLR in acute ST-segment elevation myocardial infarction (STEMI) is unclear. We investigated the possible association between peak NLR values within the first three days after STEMI onset and in-hospital outcomes in patients undergoing primary percutaneous coronary intervention (PCI).

White Blood Cell/Mean Platelet Volume Ratio as a Predictor of Long-Term Outcomes but Not Coronary Artery Disease Severity in Non-ST Elevation Myocardial Infarction Patients.

Background White blood cell count (WBC) and mean platelet volume (MPV) have been shown to be hematologic parameters of prognostic significance in acute coronary syndrome. We sought to determine the relationship between the WBC/MPV ratio (WMR), coronary artery disease (CAD) complexity, and long-term clinical outcomes in patients with non-ST elevation myocardial infarction (NSTEMI). Hypothesis WMR has a relationship with the complexity of CAD and long-term clinical outcomes in NSTEMI patients.

P wave peak time; a novel electrocardiographic parameter in the assessment of coronary no-reflow.

Objectives: Coronary no-reflow (NR) following primary percutaneous coronary intervention (pPCI) is associated with worsened prognosis in patients with ST segment elevation myocardial infarction (STEMI). Despite rapid developments in cardiovascular area; there are limited data regarding prediction of NR before pPCI. P wave duration and dispersion (PWD, PW respectively) have been studied in STEMI patients and found to be associated with reperfusion success; however none of them has been found to predict NR before PCI.

CHADS-VASc score includes similar risk factors for coronary artery disease. We hypothesized that admission CHADS-VASc score might be predictive of adverse clinical outcomes for patients with ST-segment elevation myocardial infarction (STEMI) who were undergoing primary percutaneous coronary intervention. A total of 647 patients with STEMI enrolled in this study.

The Impact of Admission Serum Creatinine Derived Estimated Glomerular Filtration Rate on Major Adverse Cardiac Events in ST-Segment Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention.

Background: The impact of Cockroft-Gault (C-G) derived estimated glomerular filtration rate (eGFR) on mortality and major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) was assessed.

Methods: A total of 884 patients were classified into four categories according to admission creatine derived eGFR: < 60, 60 - < 90, 90 - < 120, and ≥ 120 mL/min/1.73 m(2).

Admission serum potassium level is associated with in-hospital and long-term mortality in ST-elevation myocardial infarction.

ST-segment elevation of right precordial lead (V4 R) is associated with multivessel disease and increased in-hospital mortality in acute anterior myocardial infarction patients.

Background: ST segment elevation of chest lead V4 R is associated with worse prognosis in acute inferior ST-elevation myocardial infarction (STEMI). This study tried to determine the relationship between ST elevation in the right precordial lead V4 R and acute anterior STEMI.

Methods: We retrospectively analyzed 677 consecutive elderly patients (mean age 72.

Successful thrombolytic treatment of a bio-prosthetic mitral valve thrombosis in a pregnant woman.

Even though it is a rare complication, the pro-coagulant condition of pregnancy may predispose to thrombosis of a bio-prosthetic mitral valve (BPMV). We report the successful reduced-dose, slow infusion of tissue plasminogen activator (t-PA) to a BPMV thrombosis in a pregnant woman. When the patient was seen in the emergency clinic she was dyspnoeic and tachycardic and evaluated as NYHA class III-IV.

Electromechanical delay detected by tissue Doppler echocardiography is associated with the frequency of attacks in patients with lone atrial fibrillation.

Background: Our main purpose in this study is to compare atrial (inter-atrial, intra-left atrial, intra-right atrial) electromechanical delays of patients with lone atrial fibrillation (LAF) with healthy individuals and examine the relationship of annual LAF attack frequency.

Methods: 32 entirely healthy individuals and 32 patients who have presented with tachycardia and complying with LAF criteria have been included in the study. The time passing from the beginning of the P wave on electrocardiography to the A' wave on tissue Doppler trace was accepted as the atrial conduction time (PA').
