Do Sodium-Glucose Cotransporter 2 Inhibitors Decrease the Risk of Contrast-Associated Acute Kidney Injury in Patients with Type II Diabetes Mellitus?

BACKGROUND: The risk of contrast-associated acute kidney injury is relatively higher in patients with diabetes mellitus compared to non-diabetics. Recent trials have revealed the renoprotective effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors. We aimed to investigate the possible preventive effect of SGLT2 inhibitors against contrast-associated acute kidney injury in the diabetic population who underwent coronary angiography with a diagnosis of stable angina or acute coronary syndrome. METHODS: This was a cross-sectional and single-center study. We enrolled 345 patients with type II diabetes mellitus who were divided into 2 groups: using an SGLT2 inhibitor (group 1; n = 133) in addition to other antidiabetic medication and not using an SGLT2 inhibitor (group 2; n = 212). Both groups were compared in terms of contrast-associated acute kidney injury incidence. We also compared groups for the duration of hospitalization. RESULTS: Baseline characteristics (age, sex, risk factors and medications) and laboratory findings were similar between the 2 groups. The means of administered contrast volume were also similar (160.42 (± 70.31) mL vs. 158.72 (± 81.24) mL, P = 0.83) between groups 1 and 2, respectively. We found that contrast-associated acute kidney injury incidence was significantly higher in group 2 compared to group 1 (n = 56 (26.4%) vs. n = 12 (9.0%), P < 0.001). The duration of hospitalization was significantly longer in group 2 (3.25 (± 2.03) days) than in group 1 (2.54 (± 1.39) days) (P = 0.001). CONCLUSION: We found that contrast-associated acute kidney injury was significantly lower, and the duration of hospitalization was significantly shorter in diabetic patients using SGLT2 inhibitors compared to non-users.

Uma Causa Rara e Tratamento da Fibrilação Ventricular: Toxicidade do 5-Fluorouracil / A Rare Cause and Management of Ventricular Fibrillation: 5-Fluorouracil Toxicity

Resumo Um homem de 65 anos com histórico de carcinoma de língua procurou o pronto-socorro com contrações insensíveis estando em casa. Ele estava em terapia com 5-fluorouracil (5-FU) na época. O paciente foi desfibrilado e intubado porque a fibrilação ventricular (FV) se desenvolveu durante o monitoramento no pronto-socorro. A ecocardiografia mostrou que a fração de ejeção do ventrículo esquerdo (FEVE) era de 70% e a espessura do septo interventricular era de 15 mm. A angiografia coronária não revelou qualquer estenose crítica. A ressonância magnética cardíaca (RMC) não mostrou anormalidade de perfusão, fibrose ou cicatriz sugestiva de envolvimento cardíaco. Foi sugerido que a arritmia do paciente estava relacionada principalmente à cardiotoxicidade induzida pelo 5-FU. O fato de as causas secundárias terem sido proeminentes em nosso caso, de nenhuma patologia cardíaca óbvia que pudesse causar arritmia ter sido encontrada no exame detalhado e de a arritmia não ter recorrido durante a internação hospitalar, que durou até 15 dias, nos levou a acreditar que esse paciente poderia receber alta sem um cardioversor-desfibrilador implantável. Nosso caso foi apresentado para contribuir com a literatura.

Could Acute Myeloid Leukemia Have Presented Even Worse? "Uncommon Cause of Concurrently Multivessel Thrombosis". / A Leucemia Mieloide Aguda Poderia ter se Apresentado Ainda Pior? "Causa Incomum de Trombose Multiarterial Concomitante".

Acute promyelocytic leukemia (APL) is a subgroup of acute myeloid leukemia (AML). Although it is known that hemorrhagic complications are common, thrombotic complications are not as rare as thought. However, myocardial infarction and ischemic stroke incidence are very rare during AML. Here, we present the astonishing case of APL diagnosed with pancytopenia in its presentation with acute myocardial infarction and ischemic stroke.

A leucemia promielocítica aguda (LPA) é um subgrupo da leucemia mieloide aguda (LMA). Embora se saiba que as complicações hemorrágicas são comuns, as complicações trombóticas não são tão raras quanto se pensa. No entanto, infarto do miocárdio e incidência de acidente vascular cerebral isquêmico são muito raros durante a LMA. Aqui, apresentamos o caso surpreendente de LPA diagnosticada com pancitopenia em sua apresentação com infarto agudo do miocárdio e acidente vascular cerebral isquêmico.

Comparison of long-term outcome of patients with ST-segment elevation myocardial infarction between pre-COVID-19 and COVID-19 era.

AIMS: To compare major cardiovascular and cerebrovascular events (MACCE) rates between patients in the pre-COVID-19 era and COVID-19 era, and to assess the impact of the presence of COVID-19 (+) on long-term MACCE in ST-segment elevation myocardial infarction (STEMI) in Turkey. METHODS: Using the TURSER study (TURKISH ST-segment elevation myocardial infarction registry) data, the current study included 1748 STEMI patients from 15 centres in Turkey. Patients were stratified into COVID-19 era (March 11st-May 15st, 2020; n = 723) or pre-COVID-19 era (March 11st-May 15st, 2019; n = 1025) cohorts. Long-term MACCE rates were compared between groups. In addition, the effect of COVID-19 positivity on long-term outcomes was evaluated. The primary outcome was the occurrence of MACCE at long-term follow-up, and the secondary outcome was hospitalization with heart failure. RESULTS: The MACCE and hospitalization with heart failure rates between pre-COVID-19 era and COVID-19 era were 23% versus 22% (p = .841), and 12% versus 8% (p = .002), respectively. In the COVID-19 era, the rates of MACCE and hospitalization with heart failure COVID-19-positive versus COVID-19-negative patients were 40% versus 20%, (p < .001), and 43% versus 11% (p < .001), respectively. CONCLUSION: There was no difference between the pre-COVID-19 era and the COVID-19 era in terms of MACCE  in STEMI patients in Turkey. In the COVID-19 era, STEMI patients positive for COVID-19 had a higher rate of MACCE and heart failure hospitalization at the long-term follow-up.

Impact of COVID-19 outbreak on patients with ST-segment elevation myocardial infarction (STEMI) in Turkey: results from TURSER study (TURKISH St-segment elevation myocardial infarction registry).

OBJECTIVE: We aimed to investigate both the impact of COVID-19 pandemic on ST-segment elevation myocardial infarction (STEMI) admission, and demographic, angiographic, procedural characteristics, and in-hospital clinical outcomes of patients with COVID-19 positive STEMI in Turkey. METHODS: This was a multi-center and cross-sectional observational study. The study population included 1788 STEMI patients from 15 centers in Turkey. The patients were divided into two groups: COVID-19 era (March 11st-May 15st, 2020; n = 733) or pre- COVID-19 era group (March 11st-May 15st, 2019; n = 1055). Also, the patients in COVID-19 era were grouped as COVID-19 positive (n = 65) or negative (n = 668). RESULTS: There was a 30.5% drop in STEMI admission during COVID-19 era in comparison to pre-COVID-19 era. The patients admitted to the medical centers during COVID-19 era had a longer symptom-to-first medical contact time [120 (75-240) vs. 100 (60-180) minutes, p < 0.001]. COVID-19 positive STEMI patients had higher thrombus grade and lower left ventricular ejection fraction compared to COVID-19 negative patients. COVID-19 positive patients had higher mortality (28% vs. 6%, p < 0.001) and cardiogenic shock (20% vs. 7%, p < 0.001) rates compared with those without COVID-19. Matching based on propensity scores showed higher mortality and high thrombus grade in STEMI patients who were infected by SARS-COV-2 (each p < 0.05). CONCLUSIONS: We detected significantly lower STEMI hospitalization rates and significant delay in duration of symptom onset to first medical contact in the context of Turkey during the COVID-19 outbreak. Moreover, high thrombus grade and mortality were more common in COVID-19 positive STEMI patients.

The prognostic value of P-wave dispersion and left atrial functions assessed with three-dimensional echocardiography in patients with cirrhosis.

BACKGROUND: Cirrhotic cardiomyopathy (CCM) is a well-known entity. The aim of this study was to compare left atrial three-dimensional (3D) volume and P-wave dispersion (PWd) in patients with cirrhosis and a healthy population. The secondary purpose was to assess the left phasic volumes and reservoir functions with 3D echocardiography for the prediction of an increased risk of poor outcomes in patients with cirrhosis. METHODS: The study included 50 patients with cirrhosis and 43 healthy control subjects without atrial fibrillation. All patients were assessed with two-dimensional (2D), 3D, and tissue Doppler transthoracic echocardiography. The PWd was calculated using a 12-lead surface electrocardiogram (ECG). Cirrhotic patients were followed up for 2.5 years for the evaluation of poor outcomes and the development of atrial fibrillation. RESULTS: Patients with cirrhosis were observed to have significantly higher left atrial phasic volumes such as minimal left atrial volume (3D-LAVmin, P = 0.004) and indexed LAVmin (3D-LAVImin, P = 0.0001), and significantly decreased left atrial reservoir functions such as left atrial emptying volume (3D-LAEV, P = 0,001), left atrial ejection fraction (3D-LAEF, P = 0,001) on 3D echocardiography. PWd was determined to be significantly longer in the cirrhotic group compared with the control group (P = 0.003). In the 2.5-year follow-up period, poor outcomes occurred in 34 patients (22 patients died, six patients had liver transplantation, six patients developed atrial fibrillation/AHRE episodes). In Cox regression analysis, the MELD score (HR, 1.16 (1.06-1.26), P = 0.001) and 3D-LAVImin (HR, 0.95 (0.86-1.00), P = 0.040) were significantly associated with all-cause mortality. Cirrhotic patients with LAVImin of >15 ml/m2 were seen to have poor survival (long rank P = 0.033). CONCLUSION: The results of this study showed that patients with cirrhosis had higher left atrial volume, longer PWd and worse diastolic functions compared with the control group. Higher disease severity scores were associated with left atrial function and volume. In addition, left atrial volume measured with 3DE was a strong predictor of future adverse events, and minimal left atrial volumes had a higher prognostic value than any other left atrial function indices.
