Project description:Cardiogenic shock during a pheochromocytoma crisis is a life-threatening disorder. This case report illustrates a 49-year-old male with profound cardiogenic shock, extreme hemodynamic instability (systolic blood pressure ranging from 45 up to 290 mmHg in a cyclic pattern), and progressive multiple organ failure in the presence of a unilateral adrenal mass. Emergency adrenalectomy led to rapid hemodynamic stabilization. Histological investigation confirmed the diagnosis of pheochromocytoma. This case indicates that emergency adrenalectomy, although usually not considered first choice, is a valid option in cardiogenic shock and extremely fluctuating hemodynamics due to a pheochromcytoma-induced catecholamine storm.

Project description:Acute myocardial infarction (AMI) caused by severe stenosis of left main coronary artery (LMCA) presenting with cardiogenic shock and pulmonary edema during noncardiac surgery is uncommon, but a catastrophic event. A 77-year-old male with cholangiocarcinoma underwent hepatectomy. During the surgery, he presented with cardiogenic shock, which did not respond to infusion administration or vasopressor. A transesophageal echocardiogram revealed anterior, septal, and lateral severe hypokinesia and impaired left ventricular function. Emergent coronary angiogram showed severe stenosis of LMCA. The patient underwent primary percutaneous coronary intervention (PCI) under the support of intra-aortic balloon pump, followed by extracorporeal membrane oxygenation. The chest roentgenogram showed pulmonary edema. Two days after PCI, he successfully underwent hepatectomy and bile duct resection. Early identification of the cause of hemodynamic instability during noncardiac surgery and invasive strategy are important for minimizing the myocardial injury and improving clinical outcomes in AMI of LMCA.

Project description:BackgroundPheochromocytoma is a rare catecholamine-producing tumour that classically displays clinical manifestations related to alpha-adrenergic stimulation, including paroxysmal or sustained hypertension. However, it may occasionally be complicated by life-threatening crisis, leading to refractory acute heart dysfunction in the most severe cases.Case summaryA 28-year-old woman was admitted to intensive care unit due to hypertensive crisis causing pulmonary oedema, Takotsubo cardiomyopathy, and metabolic acidosis. Due to cardiogenic shock, she required venoarterial extracorporeal membrane oxygenation and IMPELLA implantation. A computed tomography scan revealed a 5 cm tumour of the left adrenal gland compatible with pheochromocytoma The clinical course was complicated by acute kidney injury requiring renal replacement therapy and posterior reversible encephalopathy syndrome (PRES). Pharmacological treatment with alpha lityc agents (including urapidil, dexmedetomidine, and doxazosin at maximum daily dose) and beta blockers, together with left videolaparoscopic adrenalectomy, led to progressive blood pressure control and resolution of the neurological symptoms.DiscussionPheochromocytoma crisis turned into a potential catastrophic scenario, characterized by refractory cardiogenic shock requiring circulatory supportive devices and PRES. Alpha-antagonists and beta-blockers were the gold standard pharmacological treatment. A multidisciplinary decision-algorithm was necessary to successfully manage this complex clinical setting.

Project description:We report a case of a 39-year-old woman who presented to the emergency department (ED) with symptoms of pharyngitis and fever. Diagnosed with streptococcal pharyngitis, she received antibiotics and dexamethasone, and was discharged. Within 24?h she returned to the ED with signs and symptoms of an acute coronary syndrome; she was thus given ?-blockers. Her coronary angiogram was normal. She developed cardiogenic shock with an ejection fraction (EF) of 10% and apical ballooning on echocardiography. Her condition improved with optimal medical therapy. Subsequent testing weeks later confirmed the presence of a pheochromocytoma. Following prazosin and an adrenalectomy, all her antihypertensive medications were weaned and her EF normalised. We believe the high-dose exogenous corticosteroids triggered a pheochromocytoma crisis. The concomitant use of ?-blockers without preceding ? blockade resulted in cardiovascular collapse. Pheochromocytoma crisis must be included in the differential diagnosis of any dramatic haemodynamic collapse after administration of exogenous corticosteroid or ?-blockers.

Project description:The aim of this study was to evaluate the pathophysiological role and the prognostic significance of pulmonary artery compliance (CPA), a measure of right ventricular pulsatile afterload, in cardiogenic shock. We retrospectively included 91 consecutive patients with cardiogenic shock due to primary left ventricular failure, monitored with a pulmonary artery catheter within the first 24?h. CPA was calculated as the ratio of stroke volume to pulmonary artery pulse pressure, and we determined whether CPA predicted mortality and whether it performed better than other pulmonary hemodynamic variables. The overall in-hospital mortality in our cohort was 27%. Survivors and nonsurvivors had comparable left ventricular ejection fraction, systolic, diastolic and mean pulmonary artery pressure, transpulmonary gradient, diastolic pressure gradient, and pulmonary vascular resistance at 24?h. In contrast, CPA was the only pulmonary artery variable significantly associated with mortality in univariate and multivariate analyses. Mortality increased from 4.5% at the highest quartile of CPA (3.6-6.5?mL/mmHg) to 43.5% at the lowest quartile (0.7-1.7?mL/mmHg). In 64 patients with a PAC inserted immediately upon admission, we calculated the trend of CPA between admission and 24?h. This trend was positive in survivors (+0.8?±?1.3?ml/mmHg) but negative in nonsurvivors (-0.1?±?1.0?mL/mmHg). The lower CPA in nonsurvivors was associated with more severe right ventricular systolic dysfunction. In conclusion, a reduced compliance of the pulmonary artery promotes right ventricular dysfunction and is independently associated with mortality in cardiogenic shock. Future studies should evaluate the impact on pulmonary arterial compliance and right ventricular afterload of therapies used in cardiogenic shock.

Project description:AimsThe aim of this study is to evaluate the contemporary use of a pulmonary artery catheter (PAC) in acute myocardial infarction-cardiogenic shock (AMI-CS).Methods and resultsA retrospective cohort of AMI-CS admissions using the National Inpatient Sample (2000-2014) was identified. Admissions with concomitant cardiac surgery or non-AMI aetiology for cardiogenic shock were excluded. The outcomes of interest were in-hospital mortality, resource utilization, and temporal trends in cohorts with and without PAC use. In the non-PAC cohort, the use and outcomes of right heart catheterization was evaluated. Multivariable regression and propensity matching was used to adjust for confounding. During 2000-2014, 364 001 admissions with AMI-CS were included. PAC was used in 8.1% with a 75% decrease during over the study period (13.9% to 5.4%). Greater proportion of admissions to urban teaching hospitals received PACs (9.5%) compared with urban non-teaching (7.1%) and rural hospitals (5.4%); P < 0.001. Younger age, male sex, white race, higher comorbidity, noncardiac organ failure, use of mechanical circulatory support, and noncardiac support were independent predictors of PAC use. The PAC cohort had higher in-hospital mortality (adjusted odds ratio 1.07 [95% confidence interval 1.04-1.10]), longer length of stay (10.9 ± 10.9 vs. 8.2 ± 9.3 days), higher hospitalization costs ($128 247 ± 138 181 vs. $96 509 ± 116 060), and lesser discharges to home (36.3% vs. 46.4%) (all P < 0.001). In 6200 propensity-matched pairs, in-hospital mortality was comparable between the two cohorts (odds ratio 1.01 [95% confidence interval 0.94-1.08]). Right heart catheterization was used in 12.5% of non-PAC admissions and was a marker of greater severity but did not indicate worse outcomes.ConclusionsIn AMI-CS, there was a 75% decrease in PAC use between 2000 and 2014. Admissions receiving a PAC were a higher risk cohort with worse clinical outcomes.

Project description:Background Cardiogenic shock (CS) is a heterogeneous syndrome with varied presentations and outcomes. We used a machine learning approach to test the hypothesis that patients with CS have distinct phenotypes at presentation, which are associated with unique clinical profiles and in-hospital mortality. Methods and Results We analyzed data from 1959 patients with CS from 2 international cohorts: CSWG (Cardiogenic Shock Working Group Registry) (myocardial infarction [CSWG-MI; n=410] and acute-on-chronic heart failure [CSWG-HF; n=480]) and the DRR (Danish Retroshock MI Registry) (n=1069). Clusters of patients with CS were identified in CSWG-MI using the consensus k means algorithm and subsequently validated in CSWG-HF and DRR. Patients in each phenotype were further categorized by their Society of Cardiovascular Angiography and Interventions staging. The machine learning algorithms revealed 3 distinct clusters in CS: "non-congested (I)", "cardiorenal (II)," and "cardiometabolic (III)" shock. Among the 3 cohorts (CSWG-MI versus DDR versus CSWG-HF), in-hospital mortality was 21% versus 28% versus 10%, 45% versus 40% versus 32%, and 55% versus 56% versus 52% for clusters I, II, and III, respectively. The "cardiometabolic shock" cluster had the highest risk of developing stage D or E shock as well as in-hospital mortality among the phenotypes, regardless of cause. Despite baseline differences, each cluster showed reproducible demographic, metabolic, and hemodynamic profiles across the 3 cohorts. Conclusions Using machine learning, we identified and validated 3 distinct CS phenotypes, with specific and reproducible associations with mortality. These phenotypes may allow for targeted patient enrollment in clinical trials and foster development of tailored treatment strategies in subsets of patients with CS.

Project description:Few studies have documented the incidence and significance of non-sustained hypotension in emergency department (ED) patients with sepsis. We hypothesized that ED non-sustained hypotension increases risk of in-hospital mortality in patients with sepsis.Secondary analysis of a prospective cohort study. ED patients aged > 17 years admitted to the hospital with explicitly defined sepsis were prospectively identified.Evidence of systemic inflammation (> 1 criteria) and suspicion for infection. Patients with overt shock were excluded. The primary outcome was in-hospital mortality.Seven hundred patients with sepsis were enrolled, including 150 (21%) with non-sustained hypotension. The primary outcome of in-hospital mortality was present in 10% (15/150) of patients with non-sustained hypotension compared with 3.6% (20/550) of patients with no hypotension. The presence of non-sustained hypotension resulted in three times the risk of mortality than no hypotension (risk ratio = 2.8, 95% CI 1.5-5.2). Patients with a lowest systolic blood pressure < 80 mmHg had a threefold increase in mortality rate compared with patients with a lowest systolic blood pressure > or = 80 mmHg (5 vs. 16%). In logistic regression analysis, non-sustained hypotension was an independent predictor of in-hospital mortality.Non-sustained hypotension in the ED confers a significantly increased risk of death during hospitalization in patients admitted with sepsis. These data should impart reluctance to dismiss non-sustained hypotension, including a single measurement, as not clinically significant or meaningful.

Project description:The incidence of cardiogenic shock is rising, patient complexity is increasing and patient survival has plateaued. Mirroring organisational innovations of elite military units, our multidisciplinary medical specialists at the INOVA Heart and Vascular Institute aim to combine the adaptability, agility and cohesion of small teams across our large healthcare system. We advocate for widespread adoption of our 'combat' methodology focused on: increased disease awareness, early multidisciplinary shock team activation, group decision-making, rapid initiation of mechanical circulatory support (as appropriate), haemodynamic-guided management, strict protocol adherence, complete data capture and regular after action reviews, with a goal of ending preventable death from cardiogenic shock.

Project description:BackgroundA 'catecholamine storm' in a case of pheochromocytoma can lead to a transient left ventricular dysfunction similar to Takotsubo cardiomyopathy. A cardiogenic shock can thus develop, with high left ventricular end-diastolic pressure and a reduction in coronary perfusion pressure. This scenario can ultimately lead to a cardiac arrest, in which unloading the left ventricle with a peripheral left ventricular assist device (Impella®) could help in achieving the return of spontaneous circulation (ROSC).Case summaryA patient affected by Takotsubo cardiomyopathy caused by a pheochromocytoma presented with cardiogenic shock that finally evolved into refractory cardiac arrest. Cardiopulmonary resuscitation was performed but ROSC was achieved only after Impella® placement.DiscussionIn the clinical scenario of Takotsubo cardiomyopathy due to pheochromocytoma, when cardiogenic shock develops treatment is difficult because exogenous catecholamines, required to maintain organ perfusion, could exacerbate hypertension and deteriorate the cardiomyopathy. Moreover, as the coronary perfusion pressure is critically reduced, refractory cardiac arrest could develop. Although veno-arterial extra-corporeal membrane oxygenation (va-ECMO) has been advocated as the treatment of choice for in-hospital refractory cardiac arrest, in the presence of left ventricular overload a device like Impella®, which carries fewer complications as compared to ECMO, could be effective in obtaining the ROSC by unloading the left ventricle.
