Future Perspectives In Acute Myocarditis Complicated By Cardiogenic Shock, Giovanni A. Tavecchia, Iside Cartella, Enrico Ammirati

Journal of Shock and Hemodynamics

Acute myocarditis is an inflammatory disease of the myocardium with a highly variable clinical course. Fulminant myocarditis (FM) represents the most threatening scenario with hemodynamic compromise and cardiogenic shock at presentation. Despite medical advances and the availability of promising mechanical circulatory support (MCS), FM is burdened by a dismal prognosis. Early referral to tertiary hospitals with MCS facilities and prompt diagnosis with endomyocardial biopsy are critical steps toward optimal management. Moreover, beyond supportive care, the prevention of irreversible myocardial damage with immunomodulating therapies must be proven in clinical trials. In this editorial, we briefly describe current evidence and future perspectives …

Surviving Sepsis Campaign: Strategies To Implement In Cardiogenic Shock Management, James Burke Md

Journal of Shock and Hemodynamics

The Surviving Sepsis Guidelines can serve as a structure to help educate and create a set of recommendations on how to care for patients through this complicated pathway of shock. Designing a cardiogenic shock bundle could reduce the variability of care and possibly improve survival. Also, a more standard protocol would allow a review of the outcomes and a system to change practice nationally when new data or technology becomes available. This could create a continuous quality improvement cycle. Creating a “Surviving Cardiogenic Shock” system could help provide awareness for recognition of cardiogenic shock and advanced management alternatives needed at …

Role Of Invasive Hemodynamics In Shock Management: Is A Pulmonary Artery Catheter Always Necessary?, Ajay J. Kirtane

Journal of Shock and Hemodynamics

The pulmonary artery (PA) catheter can be a useful tool in the management of patients with cardiogenic shock; however, there are challenges with the use of this catheter, and clinicians must balance the risks and benefits. In addition, clinicians must properly interpret data generated from a PA catheter in the context of other data to optimize a patient's hemodynamics.

Dilated Cardiomyopathy With Multiple Left Ventricular Thrombi And Embolic Stroke After Mild Covid-19, Radhapriya Yalamanchi, Madhan Kumar Murugan, Krishnaswamy Chandrasekharan, Refai Showkathali

The Texas Heart Institute Journal

COVID-19 is a novel disease with multisystem involvement, but most patients have pulmonary and cardiovascular involvement in the acute stages. The cardiovascular impact of acute COVID-19 is well recognized and ranges from myocarditis, arrhythmias, and thrombotic occlusion of coronary arteries to spontaneous coronary artery dissection and microthrombi in small coronary vessels on autopsy. We report a case of a 37-year-old man who recovered from mild COVID-19 only to present a few weeks later with devastating cardiovascular involvement that included severe left ventricular impairment resulting from nonischemic cardiomyopathy, multiple left ventricular thrombi, and embolic stroke.

Usefulness Of A Perfusion Balloon For Intraprocedural Stent Thrombosis In A Patient With St-Segment Elevated Myocardial Infarction Complicated With Cardiogenic Shock, Taro Takeyama, Yukiko Mizutani, Tetsuya Ishikawa, Kota Yamada, Hidehiko Nakamura, Shiro Nakahara, Isao Taguchi

The Texas Heart Institute Journal

Intraprocedural stent thrombosis is a rare but serious complication of reperfusion therapy for acute coronary syndrome. There is currently no consensus on the intraprocedural management of intraprocedural stent thrombosis. It is difficult to attain thrombolysis in myocardial infarction flow grade 3, particularly in cases of cardiogenic shock. A 49-year-old man who presented with anterior ST-segment elevated acute myocardial infarction with cardiogenic shock underwent emergency percutaneous coronary intervention to diffuse proximal lesions in the left anterior descending artery under the support of intra-aortic balloon pumping. Intraprocedural stent thrombosis occurred following the postdilations with a 3.5- × 38-mm everolimus-eluting stent. Despite administration …

Effects Of Escalating Temporary Mechanical Circulatory Support In Patients With Worsening Cardiogenic Shock, Iyad N Isseh, Sarah Gorgis, Carina Dagher, Shivani Sharma, Mir B Basir, Sachin Parikh

The Texas Heart Institute Journal

BACKGROUND: Cardiogenic shock-related mortality is substantial, and temporary mechanical circulatory support (MCS) devices are frequently used. The authors aimed to describe patient characteristics and outcomes in patients with worsening cardiogenic shock requiring escalation of temporary MCS devices.

METHODS: Worsening cardiogenic shock was defined as persistent hypotension, increasing doses of vasopressors/inotropes, worsening hypoperfusion, or worsening invasive hemo-dynamics. Escalation of temporary MCS devices was defined as adding or exchanging an existing MCS device. Variables were evaluated by logistic regression models and receiver operating characteristic curves.

RESULTS: From July 1, 2016, to July 1, 2018, a total of 81 consecutive patients experienced worsening …

The Texas Heart Institute Journal

BACKGROUND: Periprocedural myocardial injury is a predictor of cardiovascular morbidity and mortality after percutaneous coronary intervention.

METHODS: The authors examined the effects of preprocedural lipid levels (low-density lipoprotein, high-density lipoprotein, and triglycerides) in 977 patients with coronary artery disease who underwent elective percutaneous coronary intervention.

RESULTS: Elevated cardiac troponin I level (≥5× the upper limit of normal) was used to indicate periprocedural myocardial injury. Serum lipid samples were collected 12 hours preprocedurally. Cardiac troponin I was collected 1, 6, and 12 hours postprocedurally. Correlations between preprocedural lipid levels and postprocedural cardiac troponin I were studied. Low-density lipoprotein levels were less …

Faculty, Staff and Student Publications

Medical management of heart failure (HF) has evolved and has achieved significant survival benefits, resulting in highly complex medication regimens. Complex medication regimens create challenges for older adults, including nonadherence and increased adverse drug events, especially associated with cognitive impairment, physical limitations, or lack of social support. However, the association between medication complexity and patients' health outcomes among older adults with HF is unclear. The purpose of this review is to address how the complexity of HF medications has been assessed in the literature and what clinical outcomes are associated with medication regimen complexity in HF. Further, we aimed to …

Fight-or-flight responses involve β-adrenergic-induced increases in heart rate and contractile force. In the present study, we uncover the primary mechanism underlying the heart's innate contractile reserve. We show that four protein kinase A (PKA)-phosphorylated residues in Rad, a calcium channel inhibitor, are crucial for controlling basal calcium current and essential for β-adrenergic augmentation of calcium influx in cardiomyocytes. Even with intact PKA signaling to other proteins modulating calcium handling, preventing adrenergic activation of calcium channels in Rad-phosphosite-mutant mice (4SA-Rad) has profound physiological effects: reduced heart rate with increased pauses, reduced basal contractility, near-complete attenuation of β-adrenergic contractile response and diminished …
