    (2020) FUNDÃO, Nelson Henrique Fantin; RIBEIRO, Henrique Barbosa; CAMPOS, Carlos de Magalhães; SELEME, Vinicius Bocchino; SOEIRO, Alexandre de Matos; VIEIRA, Marcelo Luiz Campos; MATHIAS JR, Wilson; HAJJAR, Ludhmilla Abraão; RIBEIRO, Expedito E.; KALIL FILHO, Roberto
    Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

    Sonothrombolysis Promotes Improvement in Left Ventricular Wall Motion and Perfusion Scores after Acute Myocardial Infarction
    (2022) TAVARES, Bruno G.; AGUIAR, Miguel Osman; TSUTSUI, Jeane; OLIVEIRA, Mucio; SOEIRO, Alexandre de Matos; NICOLAU, Jose; RIBEIRO, Henrique; POCHIANG, Hsu; SBANO, Joao; ROCHITTE, Carlos Eduardo; LOPES, Bernardo; RAMIREZ, Jose; KALIL FILHO, Roberto; MATHIAS, Wilson
    Background: It has recently been demonstrated that the application of high-energy ultrasound and microbubbles, in a technique known as sonothrombolysis, dissolves intravascular thrombi and increases the angiographic recanalization rate in patients with ST-segment-elevation myocardial infarction (STEMI). Objective: To evaluate the effects of sonothrombolysis on left ventricular wall motion and myocardial perfusion in patients with STEMI, using real-time myocardial perfusion echocardiography (RTMPE). Methods: One hundred patients with STEMI were randomized into the following 2 groups: therapy (50 patients treated with sonothrombolysis and primary coronary angioplasty) and control (50 patients treated with primary coronary angioplasty). The patients underwent RTMPE for analysis of left ventricular ejection fraction (LVEF), wall motion score index (WMSI), and number of segments with myocardial perfusion defects 72 hours after STEMI and at 6 months of follow-up. P < 0.05 was considered statistically significant. Results: Patients treated with sonothrombolysis had higher LVEF than the control group at 72 hours (50% +/- 10% versus 44% +/- 10%; p = 0.006), and this difference was maintained at 6 months of follow-up (53% +/- 10% versus 48% +/- 12%; p = 0.008). The WMSI was similar in the therapy and control groups at 72 hours (1.62 +/- 0.39 versus 1.75 +/- 0.40; p = 0.09), but it was lower in the therapy group at 6 months (1.46 +/- 0.36 versus 1.64 +/- 0.44; p = 0.02). The number of segments with perfusion defects on RTMPE was similar in therapy and control group at 72 hours (5.92 +/- 3.47 versus 6.94 +/- 3.39; p = 0.15), but it was lower in the therapy group at 6 months (4.64 +/- 3.31 versus 6.57 +/- 4.29; p = 0.01). Conclusion: Sonothrombolysis in patients with STEMI resulted in improved wall motion and ventricular perfusion scores over time.

    Diagnostic Ultrasound Impulses Improve Microvascular Flow in Patients With STEMI Receiving Intravenous Microbubbles
    (2016) MATHIAS JR., Wilson; TSUTSUI, Jeane M.; TAVARES, Bruno G.; XIE, Feng; AGUIAR, Miguel O. D.; GARCIA, Diego R.; OLIVEIRA JR., Mucio T.; SOEIRO, Alexandre; NICOLAU, Jose C.; LEMOS NETO, Pedro A.; ROCHITTE, Carlos E.; RAMIRES, Jose A. F.; KALIL FILHO, Roberto; PORTER, Thomas R.
    BACKGROUND Pre-clinical trials have demonstrated that, during intravenous microbubble infusion, high mechanical index (HMI) impulses from a diagnostic ultrasound (DUS) transducer might restore epicardial and microvascular flow in acute ST-segment elevation myocardial infarction (STEMI). OBJECTIVES The purpose of this study was to test the safety and efficacy of this adjunctive approach in humans. METHODS From May 2014 through September 2015, patients arriving with their first STEMI were randomized to either DUS intermittent HMI impulses (n = 20) just prior to emergent percutaneous coronary intervention (PCI) and for an additional 30 min post-PCI (HMI + PCI), or low mechanical index (LMI) imaging only (n = 10) for perfusion assessments before and after PCI (LMI + PCI). All studies were conducted during an intravenous perflutren lipid microsphere infusion. A control reference group (n = 70) arrived outside of the time window of ultrasound availability and received emergent PCI alone (PCI only). Initial epicardial recanalization rates prior to emergent PCI and improvements in microvascular flow were compared between ultrasound-treated groups. RESULTS Median door-to-dilation times were 82 +/- 26 min in the LMI + PCI group, 72 +/- 15 min in the HMI + PCI group, and 103 +/- 42 min in the PCI-only group (p = NS). Angiographic recanalization prior to PCI was seen in 12 of 20 HMI + PCI patients (60%) compared with 10% of LMI + PCI and 23% of PCI-only patients (p = 0.002). There were no differences in microvascular obstructed segments prior to treatment, but there were significantly smaller proportions of obstructed segments in the HMI + PCI group at 1 month (p = 0.001) and significant improvements in left ventricular ejection fraction (p < 0.005). CONCLUSIONS HMI impulses from a diagnostic transducer, combined with a commercial microbubble infusion, can prevent microvascular obstruction and improve functional outcome when added to the contemporary PCI management of acute STEMI.

    Sonothrombolysis in ST-Segment Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention
    (2019) JR, Wilson Mathias; TSUTSUI, Jeane M.; TAVARES, Bruno G.; FAVA, Agostina M.; AGUIAR, Miguel O. D.; BORGES, Bruno C.; JR, Mucio T. Oliveira; SOEIRO, Alexandre; NICOLAU, Jose C.; RIBEIRO, Henrique B.; CHIANG, Hsu Po; SBANO, Joao C. N.; MORAD, Abdulrahman; GOLDSWEIG, Andrew; ROCHITTE, Carlos E.; LOPES, Bernardo B.

    BACKGROUND Preclinical studies have demonstrated that high mechanical index (MI) impulses from a diagnostic ultrasound transducer during an intravenous microbubble infusion (sonothrombolysis) can restore epicardial and microvascular flow in acute ST-segment elevation myocardial infarction (STEMI). OBJECTIVES This study tested the clinical effectiveness of sonothrombolysis in patients with STEMI. METHODS Patients with their first STEMI were prospectively randomized to either diagnostic ultrasound-guided high MI impulses during an intravenous Definity (Lantheus Medical Imaging, North Billerica, Massachusetts) infusion before, and following, emergent percutaneous coronary intervention (PCI), or to a control group that received PCI only (n = 50 in each group). A reference first STEMI group (n = 203) who arrived outside the randomization window was also analyzed. Angiographic recanalization before PCI, ST-segment resolution, infarct size by magnetic resonance imaging, and systolic function (LVEF) at 6 months were compared. RESULTS ST-segment resolution occurred in 16 (32%) high MI PCI versus 2 (4%) PCI-only patients before PCI, and angiographic recanalization was 48% in high MI/PCI versus 20% in PCI only and 21% in the reference group (p < 0.001). Infarct size was reduced (29 +/- 22 g high MI/PCI vs. 40 +/- 20 g PCI only; p = 0.026). LVEF was not different between groups before treatment (44 +/- 11% vs. 43 +/- 10%), but increased immediately after PCI in the high MI/PCI group (p = 0.03), and remained higher at 6 months (p = 0.015). Need for implantable defibrillator (LVEF <= 30%) was reducedin the high MI/PCI group (5% vs. 18% PCI only; p = 0.045). CONCLUSIONS Sonothrombolysis added to PCI improves recanalization rates and reduces infarct size, resulting in sustained improvements in systolic function after STEMI.
