Outcomes of Prediabetes Compared with Normoglycaemia and Diabetes Mellitus in Patients Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-analysis.

Background: Patients with prediabetes are at increased risk of coronary artery disease (CAD). However, the association between prediabetes and adverse clinical outcomes following percutaneous coronary intervention (PCI) is inconsistent, in contrast to outcomes in patients with diabetes mellitus (DM). Thus, this meta-analysis evaluated the impact of dysglycaemia on PCI outcomes. Methods: The PubMed, Embase, Cochrane, and ClinicalTrials.gov databases were systematically reviewed from inception of databases until June 2022. In 17 studies, outcomes of PCI in patients with prediabetes were compared with patients who were normoglycaemic, and patients with DM. The primary outcome was all-cause mortality at the longest follow-up. Results: Included were 12 prospective and five retrospective studies, with 11,868, 14,894 and 13,536 patients undergoing PCI in the prediabetes, normoglycaemic and DM groups, respectively. Normoglycaemic patients had a statistically lower risk of all-cause mortality, (risk ratio [RR] 0.66, 95% confidence interval [CI] 0.52-0.84), myocardial infarction (MI; RR 0.76, 95% CI 0.61-0.95) and cardiac mortality (RR 0.58, 95% CI 0.39-0.87) compared with prediabetic patients undergoing PCI at the longest follow-up. Patients with prediabetes had a lower risk of all-cause mortality (RR=0.72 [95% CI 0.53-0.97]) and cardiac mortality (RR =0.47 [95% CI 0.23-0.93]) compared with patients with DM who underwent PCI. Conclusion: Among patients who underwent PCI for CAD, the risk of all-cause and cardiac mortality, major adverse cardiovascular events and MI in prediabetic patients was higher compared with normoglycaemic patients but lower compared with patients with DM.

Catheter ablation of atrial fibrillation in hypertrophic cardiomyopathy: A proportional meta-analysis and systematic review of single-arm studies.

Background: Atrial fibrillation (AF) is the most common arrhythmia in patients with hypertrophic cardiomyopathy (HCM). Limited data exists about the efficacy and clinical outcomes of AF ablation in HCM. Objective: The purpose of this meta-analysis was to evaluate the role of catheter-based ablation for treatment of AF in patients with HCM. Methods: PubMed, SCOPUS, Web of Science, Embase, Cochrane library, and ClinicalTrials.gov were searched for studies discussing outcomes of catheter-based ablation for AF in patients with HCM. Two reviewers independently screened studies and extracted relevant data. Incidence rate estimates from individual studies underwent logit transformation to calculate the weighted summary proportion under the random effect model. Results: A total of 19 reports met the inclusion criteria (1183 patients). The single ablation procedure was successful in 39% patients. Up to 34% patients underwent a repeat ablation. About 41% patients in normal sinus rhythm after successful AF ablation received postprocedure antiarrhythmic drug (AAD) therapy. Patients undergoing successful AF ablation experienced a significant improvement in the New York Heart Association functional class (standardized mean difference -1.03; 95% confidence interval -1.23 to -0.83; P < .00001). Conclusion: AF ablation appears to be safe and feasible in patients with HCM. Freedom from AF after undergoing successful ablation is associated with significant improvement in heart failure symptoms.

Coronary Artery Aneurysms as a Cause of Acute Coronary Syndrome Presentation - A Focused Review.

Coronary artery aneurysms (CAA) are defined as a dilation of a coronary vessel greater than 1.5 times the diameter of a local reference vessel. While CAAs tend to be incidental findings on imaging, they result in complications, such as thrombosis, embolization, ischemia, arrhythmias, and heart failure. Among symptomatic cases, chest pain has been the most common manifestation of CAAs. This necessitates an understanding of CAAs as a cause of acute coronary syndrome (ACS) presentation. However, due to the unclear pathophysiology of CAAs and their variable presentation complicated by similar ACS conditions, there is no clear strategy for CAA management. In this article, we will discuss the contribution of CAAs to ACS presentations and review the current management options for CAAs.

Is Methamphetamine-Linked Cardiomyopathy an Emerging Epidemic for New Generation?

The use of methamphetamines is growing worldwide with cardiovascular disease as the leading cause of mortality and morbidity. Long-term use of methamphetamines is associated with malignant hypertension, myocardial ischemia, pulmonary hypertension, and methamphetamines-associated cardiomyopathy. These effects are noted to be dose-dependent and potentially reversible with discontinuation of methamphetamines in the early stages when there is limited or no myocardial fibrosis. This review aims to (1) summarize the available data from epidemiologic studies, (2) describe pathophysiological mechanisms and clinical presentation, (3) Management of methamphetamines induced cardiomyopathy and potential complications associated with it, and (4) Strategies to reduce methamphetamines abuse and related hospitalization.

Impella Versus Extracorporeal Membranous Oxygenation (ECMO) for Cardiogenic Shock: A Systematic Review and Meta-analysis.

The use of mechanical circulatory support (MCS) in cardiogenic shock (CS) is increasing. We conducted a systematic review and meta-analysis to compare the outcomes of Impella use with extracorporeal membranous oxygenation (ECMO) support in patients with CS. We searched the Medline, EMBASE, Cochrane, and Clinicaltrials.gov databases for observational studies comparing Impella to ECMO in patients with CS. Risk ratios (RRs) for categorical variables and standardized mean differences (SMDs) for continuous variables were calculated with 95% confidence intervals (CIs) using a random-effects model. Twelve retrospective studies and one prospective study (Impella n=6652, ECMO n=1232) were identified. Impella use was associated with lower incidence of in-hospital mortality (RR 0.88 [95% CI 0.80-0.94], P=0.0004), stroke (RR 0.30 [0.21-0.42], P<0.00001), access-site bleeding (RR 0.50 [0.37-0.69], P<0.0001), major bleeding (RR 0.56 [0.39-0.80], P=0.002), and limb ischemia (RR 0.42 [0.27-0.65], P=0.0001). Baseline lactate levels were significantly lower in the Impella group (SMD -0.52 [-0.73- -0.31], P<0.00001). There was no significant difference in mortality at 6-12 months, MCS duration, need for MCS escalation, bridge-to-LVAD or heart transplant, and renal replacement therapy use between Impella and ECMO groups. In patients with CS, Impella device use was associated with lower in-hospital mortality, stroke, and device-related complications than ECMO. However, patients in the ECMO group had higher baseline lactate levels.

Role of daratumumab in relapsed or refractory multiple myeloma patient: A meta-analysis and literature to review.

Introduction: With an increase in number of cases of relapsed or refractory multiple myeloma (RRMM), scientist have discovered various combination of medications among which one is daratumumab, Daratumumab is a mono-clonal antibody which attacks CD-38 markers present in abundance on the surface of myeloma cells and is used universally for the treatment of primary newly diagnosed multiple myeloma patients. Methods and Methodology: This meta-analysis was conducted according to Cochrane Collaboration guidelines in which initially 679 articles were evaluated for relevance on abstract level followed by full text screening of final list of 45 articles. Out of the 45 articles, only 10 articles qualified for selection criteria for eligibility. Three Phase 3 randomized control clinical trials which includes primary outcomes of progression free span and secondary outcomes including complete response, partial response or very good partial response and adverse effects reported were included in this study. Results: A total of three studies including 1533 patients (849 in Daratumumab treatment group while 684 patients in control group) were included in the study. All three of these studies were phase 3 clinical trial conducted to observe the role of daratumumab in relapsed and refractory multiple myeloma. Mean age reported was 65 years in both treatment and control groups. This study showed that daratumumab improves primary and secondary outcomes including progression free span, overall response rate, very good partial response, and complete response. However, daratumumab increases drug induced adverse effects. Conclusion: Our study confirmed that daratumumab in combination therapy improved primary and secondary outcomes when compared with platinum-based chemotherapy, but more adverse effects were reported in the combination group. So, we recommend that combination therapy should include daratumumab in treatment of relapsed and refractory multiple myeloma patients.

Prevalence of Post-Heart Transplant Malignancies: A Systematic Review and Meta-Analysis.

The prevalence of different cancers after heart transplant (HT) is unclear due to small and conflicting prior studies. Herein, we report a systematic review and meta-analysis to highlight the prevalence and pattern of malignancies post-HT. We conducted an extensive literature search on PubMed, Scopus, Cochrane databases for prospective or retrospective studies reporting malignancies after HT. The proportions from each study were subjected to random effects model that yielded the pooled estimate with 95% confidence intervals (CI). Fifty-five studies comprising 60,684 HT recipients reported 7759 total cancers during a mean follow-up of 9.8 ± 5.9 years, with an overall incidence of 15.3% (95% CI = 12.7%-18.1%). Mean time from HT to cancer diagnosis was 5.1 ± 4 years. The most frequent cancers were gastrointestinal (7.6%), skin (5.7%), and hematologic/blood (2.5%). Meta-regression showed no association between incidence of cancer and mean age at HT (coeff: -0.008; P = 0.25), percentage of male recipients (coeff: -0.001; P = 0.81), donor age (coeff: -0.011; P = 0.44), 5-year (coeff: 0.003; P = 0.12) and 10-year (coeff: 0.02; P = 0.68) post-transplant survival. There is a substantial risk of malignancies in HT recipients, most marked for gastrointestinal, skin, and hematologic. Despite their occurrence, survival is not significantly impacted.

Implementation of Multiple Evidence-Based Heart Failure Therapies.

Despite the advancements in the management of heart failure, acute heart failure is one of the most common causes of mortality and morbidity. In light of the financial burden imposed by heart failure hospitalizations on the health care system, this area remains the focus of research, clinical advances, and policy changes aimed at improving the quality of care and outcomes. Despite practice guidelines, high-quality trial data, and consensus statements, barriers to therapy remain. The barriers related to physician, patient, economic, health care system, and logistical factors prevent widespread adoption of available therapeutics. In this review article, we outline guidelines directed therapies for heart failure, challenges associated with their implementation, and potential solutions to these challenges to help reduce mortality and improve clinical outcomes in this patient population.

Transradial versus transfemoral approach for percutaneous coronary intervention in patients with ST-elevation myocardial infarction complicated by cardiogenic shock: a systematic review and meta-analysis.

BACKGROUND: In ST-elevation myocardial infarction (STEMI), transradial access (TRA) for percutaneous coronary intervention (PCI) is associated with less bleeding and mortality than transfemoral access (TFA). However, patients in cardiogenic shock (CS) are more often treated via TFA. The aim of this meta-analysis is to compare the safety and efficacy of TRA vs. TFA in CS. METHODS: Systematic review was performed querying PubMed, Google Scholar, Cochrane, and clinicaltrials.gov for studies comparing TRA to TFA in PCI for CS. Outcomes included in-hospital, 30-day and ≥1-year mortality, major and access site bleeding, TIMI3 (thrombolytics in myocardial infarction) flow, procedural success, fluoroscopy time, and contrast volume. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using random effects models. RESULTS: Six prospective and eight retrospective studies (TRA, n = 8032; TFA, n = 23 031) were identified. TRA was associated with lower in-hospital (RR 0.59, 95% CI 0.52-0.66, P < 0.0001), 30-day and ≥1-year mortality, as well as less in-hospital major (RR 0.41, 0.31-0.56, P < 0.001) and access site bleeding (RR 0.42, 0.23-0.77, P = 0.005). There were no statistically significant differences in post-PCI coronary flow grade, procedural success, fluoroscopy time, and contrast volume between TRA vs. TFA. CONCLUSIONS: In PCI for STEMI with CS, TRA is associated with significantly lower mortality and bleeding complications than TFA while achieving similar TIMI3 flow and procedural success rates.

Impact of sex on outcomes of percutaneous coronary intervention for chronic total occlusion: A meta-analysis.

BACKGROUND: Women are underrepresented in chronic total occlusion (CTO) trials and little is known about sex differences in the outcomes of CTO percutaneous coronary intervention (PCI). This meta-analysis aims to compare the outcomes of CTO PCI in males and females. METHODS: A comprehensive search of PubMed, EMBASE, Cochrane, Web of Science, and Google Scholar was performed for studies comparing outcomes of CTO PCI in females versus males from inception to January 26, 2021. The current statistical analysis was performed using STATA version 15.1 software (Stata Corporation, TX); P < 0.05 indicated statistical significance. RESULTS: Fourteen observational studies were included in the analysis with 75% males and 25% females. The mean age was 64.47 ± 10.5 years and 68.98 ± 9.5 years for males and females, respectively. The median follow-up duration was 2.4 years. Males had a higher Japanese-CTO (J-CTO) score compared with females (MD = -0.17; 95% CI: -0.25 to -0.10). Females had statistically higher success rates of CTO PCI (RR = 1.03; 95% CI: 1.01 to1.05), required less contrast volume (MD = -18.64: 95% CI: -30.89 to -6.39) and fluoroscopy time (MD = -9.12; 95% CI: -16.90 to -1.34) compared with males. There was no statistical difference in in-hospital (RR = 1.50; 95% CI: 0.73 to 3.09) or longer term (≥6 months) all-cause mortality (RR = 1.10; 95% CI: 0.86 to 1.42) between the two groups. CONCLUSIONS: CTO PCI is feasible and safe in female patients with comparable outcomes in female versus male patients.

Prognostic importance of deranged sodium level in critically ill patients: A systemic literature to review.

It is common upon admission or during stay at a hospital or intensive care unit (ICU) for patients to present with or acquire a serum sodium abnormality. Hyponatremia, serum sodium level less than 135 mmol/L, frequently associated with critical illnesses such as heart failure and liver cirrhosis, is an indicator of disease severity as well as a risk factor for poor prognosis. Hypernatremia, serum sodium level greater than 145 mmol/L, results due to any ailment disabling a patient's modality of thirst or the ability to relieve it once sensed. Hypernatremia has a more frequent iatrogenic component than hyponatremia. It can develop insidiously among patients through IV fluid administration of saline; both its presentation upon admission and development during stay is associated with mortality. Hyponatremia is associated with increased mortality and its treatment with morbidity as it carries a risk of overcorrection and consequently the development of central pontine myelinolysis. This review article covers the findings, and subsequent correlation between findings sought, of six articles catering to underscore the correlation between sodium disorders and prognosis of hospitalized or critically ill patients. PubMed search engine was utilized to select articles befitting the purpose of this review. Cumulatively, this review article substantiates the need to diligently evaluate and treat serum sodium disorders in hospitalized patients to achieve better prognosis.

Trends in 30- and 90-Day Readmission Rates for Heart Failure.

BACKGROUND: The impact of hospital readmission reduction program (HRRP) on heart failure (HF) outcomes has been debated. Limited data exist regarding trends of HF readmission rates beyond 30 days from all-payer sources. The aim of this study was to investigate temporal trends of 30- and 90-day HF readmissions rates from 2010 to 2017 in patients from all-payer sources. METHODS: The National Readmission Database was utilized to identify HF hospitalizations between 2010 and 2017. In the primary analysis, a linear trend in 30-day and 90-day readmissions from 2010 to 2017 was assessed. While in the secondary analysis, a change in aggregated 30- and 90-day all-cause and HF-specific readmissions pre-HRRP penalty phase (2010-2012) and post-HRRP penalties (2013-2017) was compared. Subgroup analyses were performed based on (1) Medicare versus non-Medicare insurance, (2) low versus high HF volume, and (3) HF with reduced versus preserved ejection fraction (heart failure with reduced ejection fraction and heart failure with preserved ejection fraction). Multiple logistic and adjusted linear regression analyses were performed for annual trends. RESULTS: A total of 6 669 313 index HF hospitalizations for 30-day, and 5 077 949 index HF hospitalizations for 90-day readmission, were included. Of these, 1 213 402 (18.2%) encounters had a readmission within 30 days, and 1 585 445 (31.2%) encounters had a readmission within 90 days. Between 2010 and 2017, both 30 and 90 days adjusted HF-specific and all-cause readmissions increased (8.1% to 8.7%, P trend 0.04, and 18.3% to 19.9%, P trend <0.001 for 30-day and 14.8% to 16.0% and 30.9% to 34.6% for 90-day, P trend <0.001 for both, respectively). Readmission rates were higher during the post-HRRP penalty period compared with pre-HRRP penalty phase (all-cause readmission 30 days: 18.6% versus 17.5%, P<0.001, all-cause readmission 90 days: 32.0% versus 29.9%, P<0.001) across all subgroups except among the low-volume hospitals. CONCLUSIONS: The rates of adjusted HF-specific and all-cause 30- and 90-day readmissions have increased from 2010 to 2017. Readmissions rates were higher during the HRRP phase across all subgroups except the low-volume hospitals.

Incidence and Management of Carfilzomib-induced Cardiovascular Toxicity; A Systematic Review and Meta-analysis.

BACKGROUND: The ASPIRE and ENDEAVOUR trials have shown cardiovascular adverse effects in patients treated with carfilzomib-based regimens. Therefore, we conducted this meta- analysis of published clinical trials to identify the cumulative incidence and risk of cardiovascular adverse effects due to carfilzomib. METHODS: A systematic search of PubMed, Embase, Web of Science, and Cochrane library was performed, and we identified 45 prospective trials of carfilzomib with data on 5583 patients. Among all patients being treated with carfilzomib (N=5,583), 8.9% sustained all grade cardiotoxicity, while 4.4% sustained high-grade cardiotoxicity. All-grade hypertension was present in 13.2%, while the incidence of high-grade hypertension was 5.3%. RESULTS: The observed incidences of all-grade heart failure, edema, and ischemia were 5.1%, 20.7%, and 4.6%, respectively. Likewise, for high-grade heart failure and edema observed incidence was 3.2%, and 2.7%, respectively. There was no difference in the event rate of all and highgrade cardiotoxicity between newly diagnosed multiple myeloma and relapsed/refractory (p-value 0.42 and 0.86, respectively). Likewise, we did not observe any difference in the event rate of all and high-grade cardiotoxicity when carfilzomib was used as a single agent versus when used in combination therapy with other agents (p-value 0.43 and 0.73, respectively). CONCLUSION: Carfilzomib is associated with a significant risk of cardiovascular toxicity and hypertension. With the increasing utilization of carfilzomib, it is critical for primary care physicians, oncologists and cardiologists to be aware of the risk of cardiotoxicity associated with the use of carfilzomib to recognize and treat baseline cardiovascular risk factors in such patients.

Outcomes of surgical versus transcatheter aortic valve replacement in nonagenarians- a systematic review and meta-analysis.

Introduction: Since the approval of transcatheter aortic valve replacement (TAVR), nonagenarian group patients are being increasingly considered for TAVR. Therefore, we compared the clinical outcomes of surgical aortic valve replacement (SAVR) vs TAVR in nonagenarians with severe aortic stenosis. Methods: A literature search was performed using MEDLINE, Embase, Web of Science, Cochrane, and Clinicaltrials.gov for studies reporting the comparative outcomes of TAVR versus SAVR in nonagenarians. The primary endpoint was short-term mortality. Secondary endpoints were post-operative incidences of stroke or transient ischemic attack (TIA), vascular complications, acute kidney injury (AKI), transfusion requirement, and length of hospital stay. Results: Four retrospective studies qualified for inclusion with a total of 8,389 patients (TAVR = 3,112, SAVR = 5,277). Short-term mortality was similar between the two groups [RR = 0.91 (95% CI: 0.76-1.10), p = 0.318]. The average length of hospital stay was shorter by 3 days in the TAVR group (p = 0.037). TAVR was associated with a significantly lower risk of AKI [RR = 0.72 (95% CI: 0.62-0.83), p < 0.001] and a lower risk of transfusion [RR = 0.71 (95% CI: 0.62-0.81), p < 0.001]. There was no difference in risk of stroke/TIA[RR = 1.01 (95% CI: 0.70-1.45), p = 0.957]. The risk of vascular complications was significantly higher in the TAVR group [RR = 3.39 (95% CI: 2.65-4.333), p < 0.001]. Conclusion: In this high-risk population, TAVR compared to SAVR has similar short-term mortality benefit but has lower risks of perioperative complications and a higher number of patients being discharged to home.

Prognostic Impact of Red Cell Distribution Width on the Development of Contrast-Induced Nephropathy, Major Adverse Cardiac Events, and Mortality in Coronary Artery Disease Patients Undergoing Percutaneous Coronary Intervention.

Red cell distribution width (RDW) serves as an independent predictor towards the prognosis of coronary artery disease (CAD) in patients undergoing percutaneous coronary intervention (PCI). A systematic search of databases such as PubMed, Embase, Web of Science, and Cochrane library was performed on October 10th, 2019, to elaborate the relationship between RDW and in hospital and long term follow up, all-cause and cardiovascular mortality, major adverse cardiac events (MACE) and development of contrast-induced nephropathy (CIN) in patients with CAD undergoing PCI. Twenty-one studies qualified this strict selection criterion (number of patients = 56,425): one study was prospective, and the rest were retrospective cohorts. Our analysis showed that patients undergoing PCI with high RDW had a significantly higher risk of in-hospital all-cause mortality (OR 2.41), long-term all-cause mortality (OR 2.44), cardiac mortality (OR 2.65), MACE (OR: 2.16), and odds of developing CIN (OR: 1.42) when compared to the patients with low RDW. Therefore, incorporating RDW in the predictive models for the development of CIN, MACE, and mortality can help in triage to improve the outcomes in coronary artery disease patients who undergo PCI.

A systematic review and meta-analysis of impact of baseline thrombocytopenia on cardiovascular outcomes and mortality in patients undergoing percutaneous coronary intervention.

BACKGROUND: Thrombocytopenia (TP) is associated with higher incidence of bleeding in the setting of percutaneous coronary intervention (PCI) leading to increased morbidity and mortality. Herein, we report a meta-analysis evaluating the effects of baseline thrombocytopenia (bTP) on cardiovascular outcomes in patients undergoing PCI. METHODS: Literature search was performed using PubMed, Embase, Cochrane library and clinicaltrials.gov from inception till October 2019. Patients were divided into two groups: Patients with (a) no Thrombocytopenia (nTP) (b) bTP before PCI. Primary endpoints were in-hospital, and all-cause mortality rates at the longest follow-up. The main summary estimate was random effects risk ratio (RR) with 95% confidence intervals (CIs). RESULTS: A total of 6,51,543 patients from 10 retrospective studies were included. There was increased in-hospital all-cause mortality (RR 2.58 [1.7-3.8], p < .001) and bleeding (RR 2.37 [1.41-3.98], p < .005), in the bTP group compared to the nTP group. There was no difference for in-hopsital major adverse cardiovascular outcomes (MACE) (RR 1.38 [0.94-2.0], p < .10), post-PCI MI (RR 1.17 [0.9-1.5], p = .19) and TVR (RR 1.65 [0.8-3.6], p = .21), respectively. Outcomes at longest follow-up showed increased incidence of all-cause mortality (RR 1.86 [1.2-2.9], p < .006) and bleeding (RR 1.72 [1.1-2.9], p = .04) in bTP group, while there was no significant difference for post-PCI MI (RR 1.07 [0.91-1.3], p = .42), MACE (RR 1.86 [0.69-1.8], p = .68) and TVR (RR 1.1 [0.9-1.2], p = .93) between both groups. CONCLUSIONS: bTP in patients undergoing PCI is associated with increased mortality and predicts risk of bleeding.

Impact of Acquired Thrombocytopenia on Cardiovascular Outcomes in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.

BACKGROUND: Acquired thrombocytopenia (aTP) is associated with a high frequency of bleeding and ischemic complications in patients undergoing percutaneous coronary intervention (PCI). Herein, we report a meta-analysis evaluating the adverse effects of aTP on cardiovascular outcomes and mortality post-PCI. METHODS: A literature search was performed using PubMed, Embase, Cochrane and, clinicaltrials.gov from the inception of these databases through October 2019. Patients were divided into two groups: 1) No Thrombocytopenia (nTP) and 2) Acquired Thrombocytopenia (aTP) after PCI. Primary endpoints were in-hospital, 30-day and all-cause mortality rates at the longest follow-up. The main summary estimate was random effects Risk ratio (RR) with 95% confidence intervals (CIs). RESULTS: Seven studies involving 57,247 participants were included. There was significantly increased in-hospital all-cause mortality (HR 10.73 [6.82-16.88]), MACE (HR 2.96 [2.24-3.94]), major bleeding (HR 4.78 [3.54-6.47]), and target vessel revascularization (TVR) (HR 7.53 [2.8-20.2]), in the aTP group compared to the nTP group. Similarly, aTP group had a statistically significant increased incidence of 30-day all-cause mortality (HR 6.08), MACE (HR 2.77), post-PCI MI (HR 1.98), TVR (HR 5.2), and major bleeding (HR 12.73). Outcomes at longest follow-up showed increased incidence of all-cause mortality (HR 3.98 [1.53-10.33]) and MACE (HR 1.24 [0.99-1.54]) in aTP group, while there was no significant difference for post-PCI MI (HR 0.94 [0.37-2.39]) and TVR (HR 0.96 [0.69-1.32]) between both groups. CONCLUSIONS: Acquired Thrombocytopenia after PCI is associated with increased morbidity, mortality, adverse bleeding events and the need for in-hospital and 30-day TVR.

Fundamentals of Light Chain Cardiac Amyloidosis: A Focused Review.

The estimated prevalence of AL CA in the US is approximately 8-12 cases per million. Almost 30-50% diagnosed cases of AL amyloid in the US have multisystem involvement, including cardiac involvement. Even with the availability of advanced diagnostic testing and novel therapies, prognosis remains poor. It is overlooked as a cause of heart failure with preserved ejection fraction leading to a delay in diagnosis when management options are limited and associated with poor survival outcomes. Therefore, the education of physicians is needed to ensure that it would be highly considered as a differential diagnosis. The purpose of this manuscript is to review the advances in the diagnosis and management of cardiac amyloidosis with the aim of educating colleagues who provide care in the primary care setting. We have summarized the pathogenesis of amyloidosis, its association with plasma cell dyscrasias, novel diagnostic and surveillance approaches including echocardiography, cardiovascular magnetic resonance imaging, histopathologic techniques, systemic biomarkers, and advanced treatment approaches including supportive symptomatic management and standard of care chemotherapy targeting the amyloid deposits. Given the overall poor prognosis of amyloidosis, we have also discussed the role of palliative and hospice care.

Sodium-Glucose Linked Transporter Inhibitors as a Cause of Euglycemic Diabetic Ketoacidosis on a Background of Starvation.

We present a case of a male diabetic patient with one of the most well-known major complications of diabetes mellitus (DM), i.e., diabetic ketoacidosis (DKA). The finding of euglycemic DKA, or DKA with blood glucose levels of less than 200 mg/dL, is a rare occurrence especially in patients with type II DM. He presented with hypotension and increased anion gap metabolic acidosis on a background of keto diet for weight loss and recent use of sodium-glucose linked transporter inhibitors. He was successfully managed with dextrose water, insulin infusion, and potassium replacement. A ketogenic diet consists of high fat, low carbohydrate, and adequate protein regimen that sends the body into a state of starvation in which high glucagon and low insulin levels lead to the activation of other counter-regulatory hormones, such as epinephrine and cortisol, that causes a rise in the level of free fatty acids in the blood increasing ketone body production. Rarely, sodium-glucose linked transport inhibitors can also cause DKA, with euglycemia instead of hyperglycemia. The finding of plasma glucose levels within normal range prompted patients to maintain and sometimes even lower their insulin dose; even their providers were often misled by the euglycemia that resulted in delayed diagnosis and treatment. Thus, it is imperative to stay aware of the possible clinical presentations in order to intervene in a timely manner and prevent further progression and complications.
