RESUMEN

AIM: To assess the relationship of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor analogues (GLP-1RA) and their combination (SGLT2i + GLP-1RA) with 5-year risk of all-cause mortality, hospitalization and cardiovascular/macrovascular disease in people with type 2 diabetes. MATERIALS AND METHODS: Retrospective cohort analysis of 2.2 million people with type 2 diabetes receiving insulin across 85 health care organizations using a global federated health research network. Three intervention cohorts (SGLT2i, GLP-1RA and SGLT2i + GLP-1RA) were compared against a control cohort (no SGLT2i/GLP-1RA). Propensity score matching for age, ischaemic heart disease, sex, hypertension, chronic kidney disease, heart failure and glycated haemoglobin was used to balance cohorts 1:1 (SGLT2i, n = 143 600; GLP-1RA, n = 186 841; SGLT-2i + GLP-1RA, n = 108 504). A sub-analysis comparing combination and monotherapy cohorts was also performed. RESULTS: The intervention cohorts showed a reduced hazard ratio (HR, 95% confidence interval) over 5 years compared with the control cohort for all-cause mortality (SGLT2i 0.49, 0.48-0.50; GLP-1RA 0.47, 0.46-0.48; combination 0.25, 0.24-0.26), hospitalization (0.73, 0.72-0.74; 0.69, 0.68-0.69; 0.60, 0.59-0.61) and acute myocardial infarct (0.75, 0.72-0.78; 0.70, 0.68-0.73; 0.63, 0.60-0.66), respectively. All other outcomes showed a significant risk reduction in favour of the intervention cohorts. The sub-analysis showed a significant risk reduction in all-cause mortality for combination therapy versus SGLT2i (0.53, 0.50-0.55) and GLP-1RA (0.56, 0.54-0.59). CONCLUSIONS: SGLT2i, GLP-1RAs or combination therapy confers mortality and cardiovascular protection in people with type 2 diabetes over 5 years. Combination therapy was associated with the greatest risk reduction in all-cause mortality versus a propensity matched control cohort. In addition, combination therapy offers a reduction in 5-year all-cause mortality when compared directly against either monotherapy.

RESUMEN

Heart failure (HF) with reduced ejection fraction (HFrEF) is a global cause of morbidity and mortality with over 60 million estimated cases worldwide. The burden of HF care is expected to increase with an ageing population as evidenced by the fact that 80% of HF-related hospitalizations occur in those aged above 65. Given the significant morbidity and mortality associated with HFrEF, there is a need for new prognostic therapies that have an impact on morbidity and mortality. In February of 2021, the National institute for Health and Care Excellence (NICE) released new guidance on the utility of Dapagliflozin for the management of heart failure with reduced ejection fraction (HFrEF). NICE advocated that dapagliflozin is a viable treatment option in symptomatic HFrEF patients on optimal medical management. The current list price of dapagliflozin is around £36.59 per 28-tablet pack with an estimated annual cost of £476.98 equating to £6939 per quality-adjusted life year. The guidance was mainly based on evidence produced from the 2019 DAPA-HF trial. This demonstrated that in HFrEF population, the use of dapagliflozin led to a significant reduction in worsening HF events, cardiovascular, and all-cause death. In this article, we summarize the evidence base for sodium-glucose co-transporter-2 inhibitors in the non-diabetic heart failure patient.

RESUMEN

ABSTRACT: Cardio-oncology is a subspeciality within cardiology that has developed primarily as a consequence of the cardiovascular implications of cancer and its therapeutics. Arrhythmias are increasingly recognized as an adverse feature of many chemotherapeutic agents. This relationship is poorly defined and studied in the literature compared with other side effects of chemotherapy. In this review, we appraise the published literature on arrhythmogenic consequences of chemotherapeutic agents and summarize the available evidence. Atrial fibrillation (AF) and other supraventricular tachycardias are frequently observed in patients receiving chemotherapy. High rates of AF are seen with certain agents such as tyrosine kinase inhibitors eg, ibrutinib and the mechanism for this is poorly defined but likely related to off-target effects. The management of AF in cardio-oncology is similar to that of the noncancer patient with certain nuances. Mainly that bleeding and stroke risk stratification tools are not validated in the cancer population. In this patient cohort, treatment decisions are usually led by anecdotal evidence rather than an evidence base. This leads to treatment heterogeneity between clinicians. Furthermore, various drug interactions can limit the choice of therapy, particularly with respect to anticoagulant drugs. Many chemotherapeutic agents have been implicated in QT interval (A Measurement calculated from the start of the Q wave to the end of the T wave on the electrocardiogram approximating the time taken for ventricular relaxation.) of these, arsenic trioxide and several tyrosine kinase inhibitors are classic culprits. In patients receiving these agents, it is advisable to perform a baseline electrocardiogram and monitor the QT interval. If the (QT interval corrected for heart rate) increases by 60 milliseconds from baseline or is greater than 500 milliseconds, it is advisable to suspend treatment temporarily. Moving forward, further trials are required in the field of cardio-oncology to better understand the relationship between chemotherapeutic agents and arrhythmia.

RESUMEN

BACKGROUND: With the exponential growth of catheter ablation for atrial fibrillation (AF), there is increasing interest in associated health care costs. Pulsed field ablation (PFA) using a single-shot pentaspline multielectrode catheter has been shown to be safe and effective for AF ablation, but its cost efficiency compared to conventional thermal ablation modalities (cryoballoon [CB] or radiofrequency [RF]) has not been evaluated. OBJECTIVE: The purpose of this study was to compare cost, efficiency, effectiveness, and safety between PFA, CB, and RF for AF ablation. METHODS: We studied 707 consecutive patients (PFA: 208 [46.0%]; CB: 325 [29.4%]; RF: 174 [24.6%]) undergoing first-time AF ablation. Individual procedural costs were calculated, including equipment, laboratory use, and hospital stay, and compared between ablation modalities, as were effectiveness and safety. RESULTS: Skin-to-skin times and catheter laboratory times were significantly shorter with PFA (68 and 102 minutes, respectively) than with CB (91 and 122 minutes) and RF (89 and 123 minutes) (P < .001). General anesthesia use differed across modalities (PFA 100%; CB 10.2%; RF 61.5%) (P < .001). Major complications occurred in 1% of cases, with no significant differences between modalities. Shorter procedural times resulted in lower staffing and laboratory costs with PFA, but these savings were offset by substantially higher equipment costs, resulting in higher overall median costs with PFA (£10,010) than with CB (£8106) and RF (£8949) (P < .001). CONCLUSION: In this contemporary real-world study of the 3 major AF ablation modalities used concurrently, PFA had shorter skin-to-skin and catheter laboratory times than did CB and RF, with similarly low rates of complications. However, PFA procedures were considerably more expensive, largely because of higher equipment cost.

RESUMEN

PURPOSE: Suboptimal glucose control early in the diagnosis of type 2 diabetes (T2D) is strongly associated with subsequent morbidity and mortality, termed the 'glycaemic legacy'. Additionally, it is known that Asian and Black individuals are at increased risk of T2D, and its associated complications compared to their White counterparts. However, ethnicity does not currently feature in the treatment algorithm of T2D, unlike in other cardiovascular disease states such as hypertension. We therefore sought to evaluate the real-world impact of early intensive treatment with combination therapy on cardiorenal outcomes compared to standard treatment in T2D, with a focus on ethnicity. METHODS: We performed a retrospective cohort study of all patients aged 18 or over with T2D using the TriNetX platform. TriNetX is a global collaborative network providing access to real time, anonymised medical records. We included patients who were initiated with Metformin and an SGLT2i within one month of diagnosis of T2D and compared this cohort with individuals who received Metformin only for a period of at least 1 year. We evaluated cardiovascular and renal outcomes at three years and stratified by ethnicity. We excluded individuals with a personal history of an outcome of interest. FINDINGS: We identified 49,651 individuals with T2D who were treated with Metformin and an SGLT2i and 1,028,806 patients with T2D who were treated with Metformin alone. A total of 98,094 individuals were included in the core analysis. The Metformin only group had a greater risk of mortality (RR 1.44, [95% CI 1.34-1.55], P<0.0001), CKD (RR 1.10, [95% CI 1.04-1.16], P = 0.0004), diabetic nephropathy (RR 1.06, [95% CI 1.01-1.12], P = 0.0239), heart failure (RR 1.13, [95% CI 1.07-1.21], P < 0.0001) and hospitalisation (RR 1.24, [95% CI 1.21-1.27], P < 0.0001) compared to individuals treated with Metformin and SGLT2i. Black individuals had a reduced risk of mortality (RR 0.71, [95% CI 0.55-0.92], P = 0.0099) and IHD (RR 0.73, [95% CI 0.64-0.84], P < 0.0001) compared to White individuals. Asian individuals had a reduced risk of heart failure (RR 0.61, [95% CI 0.41-0.91], P = 0.0134) and hospitalisation (RR 0.76, [95% CI 0.66-0.87], P = 0.0001) compared to White individuals. IMPLICATIONS: Initial combination treatment within the first year of T2D diagnosis confers favourable cardio-metabolic outcomes when compared to standard therapy, even in patients without established cardiovascular disease. Black and Asian individuals in particular demonstrate a greater degree of benefit compared to White individuals. Further prospective studies with a focus on ethnicity are now required to validate these findings.

RESUMEN

Patients with advanced chronic kidney disease (CKD) have largely been excluded from randomized control trials (RCTs) in heart failure (HF). This creates a paucity of high quality evidence for guideline directed medical therapy (GDMT), particularly in patients with heart failure with reduced ejection fraction (HFrEF) and CKD. This is a systematic review looking at the patterns and rates of inclusion of CKD in RCTs among patients with HFrEF. The search included RCTs from January 2010 to December 2020. A heat map was constructed to reflect the stages of CKD stages. The percentage of studies that included advanced CKD (stages IV-V) was recorded and log transformed, and then fitted into a time regression model. A P value of <0.05 was considered statistically significant. Out of the 3052 screened, 706 studies were included in the analysis. Only 61% of the RCTs reported at least some information on kidney function. There was a trend of increase in percentage of studies that included CKD stages IV-V from years 2010 to 2020. This was confirmed with a statistically significant linear trend P = 0.02 while the percentage of studies that included dialysis and kidney transplant recipients remained consistently low. There is a paucity of high-quality evidence for GDMT in the HFrEF population with CKD, particularly in those with advanced non-dialytic CKD, those on maintenance dialysis and kidney transplant recipients. There is a pressing need for wider inclusion of patients with advanced CKD in RCTs of GDMT in HFrEF.

RESUMEN

INTRODUCTION: Angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), angiotensin receptor-neprilysin inhibitor (ARNI), and mineralocorticoid receptor antagonists (MRA) reduce mortality and hospitalizations in heart failure with reduced ejection fraction (HFrEF) but their use is limited in advanced chronic kidney disease (CKD). METHODS: We carried out a systematic review of studies on HFrEF and CKD patients. The mean overall percentage of reported ACEI, ARB, MRA, and ARNI use, and the proportion of trials that included patients with advanced CKD grades 4-5 (estimated glomerular filtration rate (eGFR) <15-30 ml/min/1.73m2) were recorded per year. The proportion of trials with advanced CKD was logtransformed, and then fitted into a time regression model. The interactions between the proportion of trials that included CKD grades 4-5 and the proportion of reported use of ACEI, ARB, and MRAs per year were explored using Pearson's correlation and univariate linear regression. RESULTS: A total of 706 articles were included; 76% reported background ACEI/ARB use, while 51% reported MRA use. ACEI/ARB use averaged 83% and MRA 50%. Of the trials, 57% included CKD grades 4-5. Over 10 years, the proportion of trials with CKD grades 4-5 increased while ACEI/ARB use decreased. MRA use rates remained about the same. There was an inverse association found between the proportion of trials with CKD grades 4-5 and ACEI/ARB use per year. CONCLUSION: In the past 10 years, CKD grades 4-5 patients have been increasingly included in HFrEF clinical trials. Concurrently, ACEI/ARB use has reportedly decreased.

RESUMEN

Frailty is a multisystemic process leading to reduction of physiological reserve and a reduction in physical activity. Heart failure (HF) is recognised as a global cause of morbidity and mortality, increasing in prevalence over recent decades. Because of shared phenotypes and comorbidities, there is significant overlap and a bidirectional relationship, with frail patients being at increased risk of developing HF and vice versa. Despite this, frailty is not routinely assessed in patients with HF. Identification of these patients to direct multidisciplinary care is key, and the development of a frailty assessment tool validated in a large HF population is also an unmet need that would be of considerable benefit in directing multidisciplinary-team management. Non-pharmacological treatment should be included, as exercise and physical rehabilitation programmes offer dual benefit in frail HF patients, by treating both conditions simultaneously. The evidence for nutritional supplementation is mixed, but there is evidence that a personalised approach to nutritional support in frail HF patients can improve outcomes.

RESUMEN

INTRODUCTION: Heart failure (HF) with reduced ejection fraction (HFrEF) has been defined by varying ejection fraction (EF) criteria in clinical trials, leading to differences in quantifying treatment effects. AREAS COVERED: The definitions of HFrEF in randomized controlled trials from 2010 until 2020 were collected. The EF ranges were clustered into very low (<30%), low (30-39%) and mildly reduced (40-49%) stratified by intervention. A time series regression analysis was performed. A total of 3052 articles were screened and 706 were included. Interventions included were pharmacologic (37%), device therapy (10%), and a combination of programs, procedural, and laboratory testing (53%). Regarding EF cutoffs, 41% of the studies utilized <40% while 26% used <35%. About 31% did not have a clearly defined EF. Between 2010 and 2020, studies with HFrEF ranges 30-39% have significantly decreased (p value < 0.001 for trend), but those which included very low EF (<30%) and mildly reduced EF (40-49%) have remained the same. EXPERT OPINION: EF definitions across clinical trials in HFrEF varied widely. Defining the specific target HF population phenotype when designing trials or in patient treatment is important as various beneficial effects of different heart failure treatment modalities can be modified or even attenuated across the spectrum of EF.

RESUMEN

AIMS: Heart failure (HF) is associated with comorbidities which independently influence treatment response and outcomes. This retrospective observational study (January 2020-June 2021) analysed the impact of monthly HF multispecialty multidisciplinary team (MDT) meetings to address management of HF comorbidities and thereby on provision, cost of care and HF outcomes. METHODS: Patients acted as their own controls, with outcomes compared for equal periods (for each patient) pre (HF MDT) versus post-MDT (multispecialty) meeting. The multispecialty MDT comprised HF cardiologists (primary, secondary, tertiary care), HF nurses, nephrologist, endocrinologist, palliative care, chest physician, pharmacist, clinical pharmacologist and geriatrician. Outcome measures were (1) all-cause hospitalisations, (2) outpatient clinic attendances and (3) cost. RESULTS: 334 patients (mean age 72.5±11 years) were discussed virtually through MDT meetings and follow-up duration was 13.9±4 months. Mean age-adjusted Charlson Comorbidity Index was 7.6±2.1 and Rockwood Frailty Score 5.5±1.6. Multispecialty interventions included optimising diabetes therapy (haemoglobin A1c-HbA1c pre-MDT 68±11 mmol/mol vs post-MDT 61±9 mmol/mol; p<0.001), deprescribing to reduce anticholinergic burden (pre-MDT 1.85±0.4 vs 1.5±0.3 post-MDT; p<0.001), initiation of renin-angiotensin aldosterone system inhibitors in HF with reduced ejection fraction (HFrEF) with advanced chronic kidney disease (9% pre vs 71% post-MDT; p<0.001). Other interventions included potassium binders, treatment of anaemia, falls assessment, management of chest conditions, day-case ascitic, pleural drains and palliative support. Total cost of funding monthly multispecialty meetings was £32 400 and resultant 64 clinic appointments cost £9600. The post-MDT study period was associated with reduction in 481 clinic appointments (cost saving £72150) and reduced all-cause hospitalisations (pre-MDT 1.1±0.4 vs 0.6±0.1 post-MDT; p<0.001), reduction of 1586 hospital bed-days and cost savings of £634 400. Total cost saving to the healthcare system was £664 550. CONCLUSION: HF multispecialty virtual MDT model provides integrated, holistic care across all healthcare tiers for management of HF and associated comorbidities. This approach is associated with reduced clinic attendances and all-cause hospitalisations, leading to significant cost savings.

RESUMEN

Cancer and cardiovascular diseases (CVD) are among the leading causes of death worldwide. In response to the growing population of cancer patients and survivors with CVD, the sub-specialty of cardio-oncology has been developed to better optimise their care. Palpitations are one of the most common presenting complaints seen in the emergency room or by the primary care provider or cardiologist. Palpitations are defined as a rapid pulsation or abnormally rapid or irregular beating of the heart and present a complex diagnostic entity with no evidence-based guidelines currently available. Palpitations are a frequent occurrence in people with cancer, and investigations and treatment are comparable to that in the general population although there are some nuances. Cancer patients are at a higher risk of arrhythmogenic causes of palpitations and non-arrhythmogenic causes of palpitations. This review will appraise the literature with regards to the development and management of palpitations in the cancer patient.

RESUMEN

Cancer is one of the leading causes of death worldwide. Chemotherapy-induced arrhythmia is a potential complication of treatment that confers increased morbidity and mortality. The relationship between chemotherapeutic agents and arrhythmias is poorly established. Atrial fibrillation, ventricular ectopic beats, and prolonged QTc are the most common arrhythmias suffered by cancer patients undergoing chemotherapy. The treatment of atrial fibrillation in cancer is complicated by complex drug-drug interactions and a lack of evidence guiding practice. Furthermore, the normal risk assessment scores utilized in the decision-making for anticoagulation in the normal population are not validated in the cancer population. Multiple agents are implicated in prolonging the QTc, and this can often have adverse consequences for both the patient and the treatment of their cancer. This can manifest as torsades de pointes and sudden cardiac death. It is advised that, during treatment, oncologists should have close liaison with cardio-oncologists to ensure optimum patient management.

RESUMEN

Atrial fibrillation (AF) is the most common cardiac arrythmia and a major cause of stroke, heart failure, sudden death, and cardiovascular morbidity. AF increases risk of thromboembolic stroke via stasis in the left atrium and subsequent embolization to the brain. In patients with acute ischemic stroke, it is essential that clinicians undertake careful investigation to search for AF. In these patients, up to 23.7% eventually are found to have underlying AF. Oral anticoagulation is effective in prevention of strokes secondary to AF, reducing overall stroke numbers by approximately 64%. Left atrial appendage occlusion is promising for prevention of stroke in AF.

RESUMEN

BACKGROUND: Contention surrounds hydrogen and methane breath tests as putative measures of small intestinal bacterial overgrowth. We aimed to explore the clinical characteristics associated with positive and negative results to help clarify their role. METHODS: 525 glucose hydrogen/methane breath tests completed over 3 years were analyzed to look for positively and negatively associated predictive factors. Characteristics such as height and weight and underlying medical conditions, medications, and surgical history were collated. KEY RESULTS: There were 85 and 42 positive hydrogen and methane tests, respectively. Patients with irritable bowel syndrome (IBS) (HR = 0.17, p = 0.004) and those with a higher body mass index (HR = 0.93, p = 0.004) were significantly less likely to have a positive test. Patients who underwent the test post-surgically were significantly more likely to have a positive test (HR = 2.76, p = 0.001). A sub-analysis of post-surgical patients by type and region of surgical resection demonstrated that none were statistically more likely than the next to have a positive test. However, for the surgical group as a whole the number of motility-depressing drugs taken (such as opioids) was associated with a significantly decreased likelihood of a positive test (HR = 0.752, p = 0.045). CONCLUSION: Our data suggest that patients with a diagnosis of IBS are statistically less likely to have a positive test and it is of limited utility in this group. Post-surgical patients are more likely to have a positive test, possibly secondary to fast transit rather than bacterial overgrowth, as suggested by a significantly negative association with motility-suppressing drugs in this sub-group.

RESUMEN

AIMS: The coronavirus disease 2019 (COVID-19) pandemic has created significant challenges to healthcare globally, necessitating rapid restructuring of service provision. This questionnaire survey was conducted amongst adult heart failure (HF) patients in the United Kingdom (UK), to understand the impact of COVID-19 upon HF services. METHODS AND RESULTS: The survey was conducted by the Pumping Marvellous Foundation, a UK HF patient charity. 'Survey Monkey' was used to disseminate the questionnaire in the Pumping Marvellous Foundation 's online patient group and in 10 UK hospitals (outpatient hospital and community HF clinics). There were 1050 responses collected (693/1050-66% women); 55% (579/1050) were aged over 60 years. Anxiety level was significantly higher regarding COVID-19 (mean 7 ± 2.5 on anxiety scale of 0 to 10) compared with anxiety regarding HF (6.1 ± 2.4; P < 0.001). Anxiety was higher amongst patients aged ≤60 years about HF (6.3 ± 2.2 vs. 5.9 ± 2.5 in those aged >60 years; P = 0.005) and COVID-19 (7.3 ± 2.3 vs. 6.7 ± 2.6 those aged >60 years; P < 0.001). Sixty-five per cent of respondents (686/1050) reported disruption to HF appointments (cancellation or postponement) during the lockdown period. Thirty-seven per cent reported disruption to medication prescription services, and Thirty-four per cent reported inability to access their HF teams promptly. Thirty-two per cent expressed reluctance to attend hospital (25% stated they would only attend hospital if there was no alternative, and 7% stated that they would not attend hospital at all). CONCLUSIONS: The COVID-19 pandemic has caused significant anxiety amongst HF patients regarding COVID-19 and HF. Cancellation or postponement of scheduled clinic appointments, investigations, procedures, prescription, and monitoring services were implicated as sources of anxiety.

RESUMEN

INTRODUCTION: Peripheral artery disease (PAD) is a prevalent but underdiagnosed manifestation of atherosclerosis that has a worse prognosis than coronary artery disease. Patients with PAD are at heightened risk of both systemic cardiovascular adverse events and limb-related morbidity. There is insufficient awareness of its clinical manifestations, including intermittent claudication and critical limb ischemia and of its risk of adverse cardiovascular and limb outcomes. AREAS COVERED: The authors present the current knowledge concerning medications and their mechanism of action, landmark trials, and the evidence base behind the most commonly utilized pharmacological therapy including but not limited aspirin, clopidogrel, ticagrelor, warfarin, rivaroxaban, statins, angiotensin-converting enzyme inhibitors, Evolocumab and Ezetimibe. EXPERT OPINION: Relative to coronary artery disease, peripheral artery disease is an undertreated and under-investigated condition. The majority of the evidence base in the management of PAD is extrapolated from data subsets of large trials examining different conditions. This creates a paucity of management decisions based on trials powered for outcomes in PAD.

RESUMEN

Cancer is one of the leading causes of death worldwide. During the last few decades prognosis has improved dramatically and patients are living longer and suffering long-term cardiovascular consequences of chemotherapeutic agents. Cardiovascular disease is a leading cause of morbidity and mortality in cancer survivors second only to recurrent cancer. In some types of cancer, cardiovascular disease is a more common cause of death than the cancer itself. This has led to a new sub-specialty of cardiology coined cardio-oncology to manage this specific population. Hypertension is one of the most common cardiovascular disease seen in this cohort. The aetiology of hypertension in cardio-oncology is complex and multifactorial based on the type of chemotherapy, type of malignancy and intrinsic patient factors such as age and pre-existing comorbidities. A variety of different oncological treatments have been implicated in causing hypertension. The effect can be transient whilst undergoing treatment or can be delayed occurring decades after treatment. A tailored management plan is recommended given the plethora of agents and their differing underlying mechanisms and speed of this mechanism in causing hypertension. Management by a multidisciplinary team consisting of oncology, general practice and cardiology is advised. There are currently no trials comparing antihypertensives in this specific cohort of patients. In the absence of evidence demonstrating otherwise, hypertension in cardio-oncology should be managed utilising the same treatment guidelines for the general population.
