RESUMEN

PURPOSE OF REVIEW: Hypertension (HTN) remains the most common and strongest contributing factor to the development of heart failure with preserved ejection fraction (HFpEF). In this review, we aim to summarize the pathophysiological processes linking HTN to HFpEF and highlight novel concepts in medical and device-based management of HFpEF and HTN. RECENT FINDINGS: Despite the global increase in the prevalence of HFpEF, there has been limited benefit in current medication and device-based therapy for this complex syndrome. The hallmark of HFpEF is an elevated left intra-atrial and ventricular pressure and exertional dyspnea. Traditional medications used for treating HTN in patients with reduced left ventricular ejection fraction have unclear benefits in patients with HFpEF. Careful analysis of emerging medications such as angiotensin receptor-neprilysin inhibitor and sodium-glucose co-transporter-2 inhibitors showed benefit in reducing not only blood pressure but also hospitalizations in patients with HFpEF. Current data on device-based therapy aims to reduce left intra-atrial pressure, ventricular pressure and stimulate baroreceptors to lower blood pressure; however, needs further investigation. SUMMARY: The nexus of HTN and HFpEF remains strong and complex. Although traditional medications for treating HFrEF did not affect long-term outcomes, novel therapies with angiotensin receptor neprilysin-inhibitor and sodium-glucose co-transporter-2 inhibitor offer promising results. Many device-based interventions in the HFpEF population are being developed with the aim to reduce left intra-atrial and ventricular pressure; however, their role in HFpEF hypertensive patients needs to be further investigated.

RESUMEN

BACKGROUND: Left ventricular assist devices (LVAD) outflow graft obstruction is an uncommon complication but carries significant morbidity and mortality. Here we provide a case series of patients with LVAD intrinsic outflow graft obstruction who are deemed to be a high surgical risk for pump exchange and, therefore, underwent percutaneous intervention with the concomitant use of neuroprotective device-Sentinel cerebral protection system (CPS) (Boston Scientific) to prevent embolic stroke. METHODS: We retrospectively analyzed patients who underwent LVAD placement in our institution and developed LVAD outflow graft obstruction. The diagnosis of LVAD outflow graft obstruction was confirmed by utilizing various cardiac imaging modalities such as echocardiography and/or computed tomography angiography. All patients were treated with percutaneous intervention and a catheter-based CPS. RESULTS: From a total of 501 LVAD implants in our institute, 6 (1.2%) patients with LVAD outflow graft obstruction who underwent percutaneous treatment were included; 4 patients with HeartMate-III LVAD, 1 patient with HeartMate-II LVAD, and 1 patient with HeartWare (HVAD). The median age of patients was 56.5 years at the time of LVAD implantation. The median time from the LVAD implantation to the episode of LVAD outflow obstruction was 1343 days. Utilization of Sentinel CPS resulted in the capture and removal of thrombus/debris in all patients. CONCLUSIONS: Percutaneous intervention of LVAD outflow graft obstruction is less invasive than surgical pump exchange and an acceptable alternative in properly selected patients. In our experience, utilization of a catheter-based CPS can help in reducing the incidence of periprocedural embolic events.

RESUMEN

Hypertriglyceridemia-induced acute pancreatitis (HGAP) is the third most common etiology of acute pancreatitis. HGAP can be attributed to genetic disturbances in triglyceride metabolism or multiple secondary causes. Here, we presented three cases for HGAP and explored different therapeutic approaches for treating HGAP. A case series of three patients who presented with HGAP and underwent different therapeutic approaches was conducted. The first patient was a 37-year-old male who presented with nonsevere HGAP; he was treated with conservative therapy with insulin and heparin infusion, which resulted in clinical and laboratory improvement. The second patient was a 64-year-old male with human immunodeficiency virus on multiple highly active antiretroviral therapy. He presented with severe HGAP and multiorgan failure. After initiation of therapeutic plasma exchange, his HGAP resolved. The third patient was a 28-year-old male who presented with recurrent episodes of HGAP; his conservative therapy failed and was eventually escalated to therapeutic plasma exchange (TPE). HGAP can be attributed to genetic disturbances of lipid or secondary etiologies. A nonsevere form of HGAP can be managed with conventional therapy including insulin and heparin; however, severe HGAP may require TPE.

RESUMEN

SIGNIFICANCE: Amiodarone is an excellent antiarrhythmic medication; however, it has numerous systemic and ocular adverse effects. PURPOSE: We aimed to improve our understanding of amiodarone and its ocular adverse effects by performing a systematic review and meta-analysis of published case reports. METHODS: This systematic review was reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. We used the MEDLINE database, primarily through PubMed, and used keywords (amiodarone, eye, eye diseases, visual/ocular adverse effects/manifestations) to identify case reports of ocular adverse effects after amiodarone use. The initial search resulted in 92 total case reports. However, after excluding nonrelevant case reports, 25 cases were selected for the final analysis. RESULTS: Among the patients in the 25 case reports, 18 were male (72%), and the median age was 66 ± 9.9 years. In 15 cases (60%), the patients reported halos around light and/or decrease in vision after amiodarone use. The most common ophthalmic examination findings were cornea verticillata/vortex keratopathy in 19 cases (76%), followed by different patterns of papilledema and retinal hemorrhages in 5 cases (20%). Discontinuation of amiodarone was the most common intervention, followed by application of topical heparin. Outcomes among case reports were variable. CONCLUSIONS: Cornea verticillata/vortex keratopathy was the most common ocular adverse effect in cases where amiodarone was administered. Early recognition of amiodarone-induced ocular adverse effects is imperative to prevent worsening keratopathy or uncommon adverse effects. Collaboration between physicians prescribing amiodarone-to recognize the ocular symptoms-and referral to eye care physicians are important.

RESUMEN

The Internet is one of the major sources for health information for patients and their families, particularly when patients face serious life-threatening conditions such as kidney cancer in adults. In this study, we evaluate the content and quality of health information on adult kidney cancer using several validated instruments. We accessed the three most popular search engines (Google, Yahoo, Bing), using two terms: "kidney cancer" and "renal cell carcinoma," and reviewed the top 30 hits. After exclusion of duplicated websites, websites targeting health care professionals, and unrelated websites, 35 websites were included. Content was assessed using a 22-item checklist adapted from the American Cancer Society. We assessed website quality using the DISCERN questionnaire, HONcode and JAMA benchmark criteria, readability using three readability scores, and ALEXA for global traffic ranking systems. The average website had 16 of 22 content items while 6 websites fulfilled all 22 items. Among all websites, the average DISCERN quality score was 42 out of 80, 15 (42.8 %) of websites had HONcode certification, and only 3 (8.5 %) fulfilled all JAMA benchmark criteria. The average website readability was at the ninth grade reading level. The content and quality of health-related information on the Internet for adult kidney cancer are variable in comprehensiveness and quality. Many websites are difficult to read without a high school education. A standardized approach to presenting cancer information on the Internet for patients and families may be warranted.

RESUMEN

PURPOSE: Self-medication is common worldwide. However, the prevalence of sale of prescription medications without prescription and the quality of assessment and counselling provided by community pharmacists to cardiac patients is unknown. We sought to determine the prevalence of prescription medication sales and explore how pharmacists assess and counsel patients with acute cardiac conditions. METHODS: Six hundred community pharmacies in the two largest cities in Saudi Arabia were selected. Two simulated clients presented either an acute coronary syndrome (ACS) scenario or an acute heart failure (AHF) scenario to the pharmacists. Descriptive statistics and regression models were used to analyse and present the collected data. RESULTS: Of 600 pharmacies, 379 (63.2%) sold various prescription medications to simulated patients without prescription. Assessment and counselling provided by pharmacists were inadequate. Almost a quarter of pharmacists did not ask simulated patients any questions; 52% asked one or two questions; and only 24% asked three or more questions. Only 28 pharmacists (4.7%) inquired about drug allergies; 48.5% instructed simulated patients on the dosage and frequency of the sold medications; 21.6% provided instruction on treatment duration; and 19.4% gave instructions on dose, frequency, and duration of treatment. Compared to AHF, ACS simulated patients were more likely to be asked about other symptoms and comorbidities (59.7% vs. 48.7%, p = 0.007 and 46.3% vs. 37.3%, p = 0.005, respectively) and were more likely to be advised to go to hospital (70.3% vs. 56.3%, p < 0.001). CONCLUSIONS: The sale of prescription medications by community pharmacists to simulated cardiac patients without prescription is very common; assessment and counselling qualities are suboptimal.

RESUMEN

Background: Excluding spontaneous coronary artery dissection (SCAD) as an aetiology of acute coronary syndrome in young adults is imperative. Case summary: A previously healthy 39-year-old woman experienced sudden severe chest pain, ST-segment elevation on electrocardiogram, necessitating high-dose aspirin and urgent transfer to a revascularization centre. Suffering ventricular tachycardia (VT) and ventricular fibrillation (VF), she underwent two rounds of advanced life support and venoarterial extracorporeal membrane oxygenation. Diagnosed with left main coronary artery (LMCA) SCAD, she was initially started on conservative therapy for declining left ventricular ejection fraction. However, she continued to experience an escalating anginal symptoms, worsening biomarkers, and LMCA SCAD progression, which urged the need for surgical intervention with coronary artery bypass graft surgery (CABG). Following her CABG, she experienced a worsening of her functional mitral regurgitating, which she underwent transcatheter edge-to-edge repair of her severe mitral regurgitation. Despite being listed for orthotopic heart transplantation (OHTx), her low body mass index and elevated antibodies necessitated the HeartMate III left ventricular assist device (LVAD) for bridge to transplant. After treating frequent VT episodes with medications, she eventually received a LVAD as a bridge to cardiac transplantation. Within 1 year of her receiving LVAD, she underwent a successful OHTx. Discussion: The pathogenesis of SCAD involves intramural haematoma formation through intimal tears or vasa vasorum haemorrhage. Adverse outcomes that could occur in SCAD patients include cardiac arrest, cardiogenic shock, reduced left ventricle systolic function, and occasionally serious cardiac arrhythmia-such as VF-which can lead to sudden cardiac death. Although most SCAD cases heal spontaneously, revascularization can be considered in case of worsening SCAD progression. Advanced therapeutic intervention including mechanical circulatory support and OHTx should be considered in refractory cases.

RESUMEN

BACKGROUND: This study evaluated the effects of canagliflozin in patients with type 2 diabetes with and without prevalent cardiovascular disease (secondary and primary prevention). METHODS AND RESULTS: This was a pooled participant-level analysis of the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program and CREDENCE (Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation) trial. The CANVAS Program included participants with type 2 diabetes at elevated cardiovascular risk, whereas the CREDENCE trial included participants with type 2 diabetes and albuminuric chronic kidney disease. Hazard ratios (HRs) with interaction terms were obtained from Cox regression models to estimate relative risk reduction with canagliflozin versus placebo across the primary and secondary prevention groups. We analyzed 5616 (38.9%) and 8804 (61.1%) individuals in the primary and secondary prevention subgroups, respectively. Primary versus secondary prevention participants were on average younger (62.2 versus 63.8 years of age) and more often women (42% versus 31%). Canagliflozin reduced the risk of major adverse cardiovascular events (HR, 0.84 [95% CI, 0.76-0.94]) consistently across primary and secondary prevention subgroups (Pinteraction=0.86). Similarly, no treatment effect heterogeneity was observed with canagliflozin for hospitalization for heart failure, cardiovascular death, end-stage kidney disease, or all-cause mortality (all Pinteraction>0.5). CONCLUSIONS: Canagliflozin reduced cardiovascular and kidney outcomes with no statistical evidence of heterogeneity for the treatment effect across the primary and secondary prevention subgroups in the CANVAS Program and CREDENCE trial. Although studies on the optimal implementation of canagliflozin within these populations are warranted, these results reinforce canagliflozin's role in cardiorenal prevention and treatment in individuals with type 2 diabetes.

RESUMEN

Patients with left ventricular assist devices (LVADs) who require intermittent hemodialysis (iHD) are considered to have a poor prognosis despite a paucity of supportive evidence, mostly from small single-center cohorts and extrapolations from studies of patients who received continuous renal replacement therapy but no iHD. We conducted a systematic review and individual-participant-data meta-analysis of the literature including our single-center cohort to examine the outcomes of patients initiated on iHD following LVAD implantation. Sixty-four patients from 5 cohorts met selection criteria (age 57.5 [46-64.5] years, 87% HeartMate II, mostly bridge to transplantation). Follow-up after iHD initiation was 87.5 (38.5-269.5) days, although it was considerably longer in our center than in other cohorts (601.5 [93-1559] days vs 65 [26-180] days, P = 0.0007). The estimated median survival was 308 (76-912.5) days and varied significantly among cohorts, ranging from 60 (57-65) to 838 (103-1872) days (P = 0.0096). Twelve (18.8%) patients achieved either heart transplantation (HT) or remission during follow-up. Patients who received HT had an 8-fold longer estimated median survival (1972 [799-1972] days vs 244 [64-838] days, P = 0.0112). Being from a more recent cohort was associated with better 1-year survival. Renal recovery occurred in eight patients (13.1%) at 30 days and its cumulative incidence increased to 73% (27/37 patients with available data) at 1 year. Most patients initiated on iHD after LVAD experienced renal recovery within the first year after implantation. Improved survival was observed for patients who received HT and in those from more recent cohorts. Some patients were able to survive on LVAD and iHD support for several years.

RESUMEN

Background: Giant cell myocarditis (GCM) is a severe and rapidly progressing condition that can lead to end-stage heart failure. We present a case of a 51-year-old male with a history of orthotopic heart transplantation (OHTx) for GCM, who experienced recurrent GCM in the allograft, leading to progressive heart failure and the need for a second heart transplant. Case summary: A 51-year-old male with a history of OHTx for GCM presented with rapidly worsening heart failure symptoms. Despite initial stability, he deteriorated to cardiogenic shock and required intensive support. His clinical course was complicated by recurrent COVID-19 infections, worsened left ventricular ejection fraction, and withdrawal of guideline-directed medical therapy. Imaging showed extensive scar burden, and subsequent investigations ruled out coronary artery disease. With declining functional status and worsening cardiogenic shock, he was re-listed for OHTx and successfully underwent a second heart transplant. Discussion: Giant cell myocarditis poses challenges due to its aggressive nature. Early, aggressive immunosuppression and mechanical circulatory support are crucial. The recurrence rate of GCM post-OHTx is notable, often within the first year, and the optimal immunosuppressive regimen remains uncertain. In this case, GCM recurrence following OHTx led to continued deterioration despite treatment, necessitating a second heart transplant. This unique case emphasizes the complexity of managing recurrent GCM post-OHTx.

RESUMEN

Cardiac amyloidosis (CA) is a complex disease considered to be the most common underdiagnosed form of restrictive cardiomyopathy. Accumulation of misfolded proteins called amyloid fibrils in the extracellular space results in clinical deterioration and late diagnosis is associated with morbidity and mortality. Both types of this disease, light chain CA and transthyretin-related CA share many cardiac and extracardiac features that compromise multiple organs such as kidneys, musculoskeletal system, autonomic nervous system, and gastrointestinal tract. Early diagnosis and detection of CA are imperative. Clinicians should maintain a high degree of suspicion among patients with unexplained diastolic heart failure to implement different disease-altering therapies at the early stages of the disease. In this article, we provided a comprehensive review of multiple invasive and non-invasive cardiac imaging modalities with their respective degrees of sensitivities and specificity.

RESUMEN

INTRODUCTION: Endogenous testosterone deficiency or excess anabolic-androgenic steroids (AAS) have been linked to alter the physiology of different organs in the body, more specifically, the vasculature of coronary arteries. Despite the health-related concerns of using synthetic testosterone derivatives, such as AAS, there has been a tremendous increase in the use of AAS among athletes and bodybuilders. AREAS COVERED: We have highlighted the three main mechanisms that AAS increase the risk of coronary artery disease (CAD): altering the homeostasis of lipid metabolism which results in dyslipidemia and subsequently atherosclerosis, disturbing the function of platelet which results in platelet aggregation and subsequent thrombosis, and increasing the risk of coronary vasospasm by affecting the physiological function of vascular bed. EXPERT OPINION: Despite the restriction of AAS in specific clinical conditions such as testosterone deficiency and cancer therapy, many amateurs' athletes misuse the AAS. Although there has been a strong association between the AAS misuse and risk of developing CAD, the more valued approach would be a randomized clinical double-blind trial. The suggested primary endpoint would be an occurrence of adverse cardiovascular events, such as myocardial infarction, cerebrovascular accidents, and death. Increasing awareness of the risk of missing AAS among high-risk groups is imperative.

RESUMEN

Early detection and risk stratification of patients with heart failure (HF) are crucial to improve outcomes. Given the complexity of the pathophysiological processes of HF and the involvement of multi-organ systems in different stages of HF, clinical prognostication of HF can be challenging. In this regard, several biomarkers have been investigated for diagnosis, screening, and risk stratification of HF patients. These biomarkers can be classified as biomarkers of myocardial stretch such as B-type natriuretic peptide, biomarkers of neurohormonal activation, biomarkers of inflammation and oxidative stress and biomarkers of cardiac hypertrophy, fibrosis and remodeling. In this paper, we summarize current evidence supporting the use of selected biomarkers in HF. We review their diagnostic, prognostic and therapeutic role in the management of HF. We also discuss potential factors limiting the use of these novel biomarkers in the clinical practice and highlight the challenges of adopting a multi-biomarker strategy.

RESUMEN

Prothesis-patient mismatch (PPM) occurs when there is a mismatch between the effective orifice area (EOA) of the prosthetic valve and the required cardiac output to meet the need of the patient's body surface area (BSA). The clinical threshold for PPM occurs when the indexed effective orifice area (iEOA) is ≤0.65 cm2/m2 for the aortic valve prosthesis, and ≤ 1.20 cm2/m2 for the mitral valve prosthesis. The wide variation of reported incidence of PPM is most likely attributed to the variation in the methods of calculating iEOA [(for e.g., using continuity equation across the prosthesis versus using projected EOA (generated by the industry)]. Newer generation mechanical valves have shown less PPM than older generation, and stentless bioprosthesis have less PPM than stented prosthesis. Long-term clinical outcome of PPM is associated with adverse cardiovascular events especially in the presence of pre-existing left ventricle dysfunction or with concomitant procedure such as coronary artery bypass graft surgery. Strategies to mitigate the risk of PPM such as aortic root replacement in patients with the small aortic annulus should be utilized. Accurate assessment of the patient's annular size and indexing the effective orifice area (EOA) of the prosthesis to patient's BSA at the time of prosthesis implantation are important steps to preventing future PPM.

RESUMEN

Left atrial appendage (LAA) occlusion devices provided an acceptable and valid alternative to anticoagulation among patients with atrial fibrillation who carry high bleeding risk. Watchman device is non-inferior to oral anticoagulation to prevent cerebrovascular accidents. The presence of a longer distal portion of the older generation Watchman led to exclusion of patients with prohibitive anatomy of the LAA such as chicken-wing morphology or shallow LAA. Watchman FLX provides a wider range of sizes and can be implanted with complex anatomy or shallow LAA. In the case series, we discuss 3 patients with challenging LAA anatomy that underwent successful Watchman FLX implantation.

RESUMEN

Cardiac amyloidosis is a systemic disease characterized by continuous deposition of misfolded proteins called amyloid fibrils in the extracellular space which result in restrictive cardiomyopathy. The most common form of cardiac amyloidosis is light chain (AL) cardiac amyloidosis, a result of continuous deposition of misfolded monoclonal immunoglobulin light chains. Transthyretin-related cardiac amyloidosis (ATTR) results from a point mutation in the transthyretin gene in an autosomal dominant fashion and presents phenotypically similar to AL cardiac amyloidosis. Cardiac amyloidosis is being increasingly recognized due to the advancements in diagnostic cardiac imaging and pharmacotherapy. Clinicians should maintain a high index of suspicion among patients with unexplained diastolic heart failure because earlier diagnosis will allow for the implementation of disease-altering therapy. With established targeted drug therapies and further breakthroughs in immunotherapy, the potential impact of diagnostic and therapeutic advancements on morbidity and mortality of patients with cardiac amyloidosis is promising.

RESUMEN

There is an increasing need for alternative access in patients with prohibitive surgical risk who have unsuitable anatomy for transfemoral transcatheter aortic valve replacement (TAVR). Data on differences in periprocedural outcomes via alternative access sites are scarce. We performed a retrospective analysis of patients who underwent Transaxillary (TAX) or Transapical (TAP) TAVR at our center from 2012 to 2019. All data was summarized and displayed as mean ± SD for continuous variables and number of patients in each group. A propensity score was created for each patient in the dataset to determine the probability of axillary vs apical access. We adjusted for propensity score using multivariate logistic regression. A total of 102 patients underwent TAVR via alternative access: 28 patients (27%) via TAX and 74 patients (73%) via transapical (TAP) access. The average time to extubation in the TAX group was 5.3 ± 3.5 hours vs 9.1 ± 8.8 hours in the TAP patients (P = 0.03). None of the TAX patients required reintubation compared to 23% of TAP TAVR (P = 0.003). The average hospital length of stay for TAX was 2.4 ± 2.0 days compared to 6.9 ± 3.3 days (P < 0.0001) for TAP. TAX TAVR patients had significantly lower re-intubation rates, shorter time to extubation and in-hospital length of stay, but higher pacemaker implantation rates. TAX TAVR had improved periprocedural outcomes compared to TAP TAVR and remains the preferred TAVR alternative access.

RESUMEN

In the last decade, advances in wireless and sensor technologies, and the implementation of telemedicine, have led to innovative digital health care for cardiac patients. Continuous monitoring of patients' biomedical signals, and acute changes in these signals, may result in timely, accurate diagnoses and implementation of early interventions. In this review, we discuss commonly used wireless and leadless cardiac devices including pulmonary artery pressure sensors, implantable loop recorders, leadless pacemakers and subcutaneous implantable cardioverter-defibrillators. We discuss the concept and function of each device, indications, methods of delivery, potential complications, consideration for implantation, and cost-effectiveness.

RESUMEN

Background: Fungal infections are known for their chronicity and latency and are difficult to eradicate. The pathophysiology of these invading pathogens and the resulting alteration of the immune system are not fully understood. Fungal meningitis is associated with significant rates of morbidity and mortality, especially among immunocompromised patients. Cryptococcosis, an infection secondary to the fungus Cryptococcus, is one of the most important opportunistic infections among patients with human immunodeficiency virus (HIV), and expediting treatment is crucial. Case Report: We report the case of a 28-year-old male with HIV who had a simultaneous co-infection with cryptococcal meningitis and Mycobacterium avium complex (MAC). The patient required a 2-week induction phase of antifungal medication with amphotericin B and flucytosine. Despite aggressive initial therapy and the patient's significant clinical improvement, his radiologic findings and lumbar puncture showed persistent cryptococcal infection. Conclusion: Concurrent infection with cryptococcosis and MAC is extremely rare even in immunosuppressed patients. In our case, the concurrent infection was associated with a prolonged course of therapy during the induction phase for cryptococcosis.
