Whether routine use of spironolactone is beneficial after myocardial infarction is uncertain.  Recent attempts to improve outcomes with intensified renin–angiotensin–aldosterone inhibition have not shown improvements in outcomes.7,8 A trial of routine aldosterone antagonism with spironolactone in addition to standard therapy among 1603 patients after myocardial infarction without heart failure showed no improvement in outcomes.9  https://pubmed.ncbi.nlm.nih.gov/27102506/   “ In a non-pre-specified exploratory analysis, the odds of death were reduced in the treatment group (3 [0.5%] vs. 15 [2.4%]; HR: 0.20; 95% CI: 0.06 to 0.70) in the subgroup of ST-segment elevation MI (n = 1,229), but not in non-ST-segment elevation MI (p for interaction = 0.01).”’ However, there was a significant reductio

    Estimated 5-year incidence of recurrent VTE was similar in the reduced-dose and full-dose groups (2.2% and 1.8%). Estimated 5-year bleeding incidence was significantly lower with reduced-dose than with full-dose treatment (2.1% vs. 4.0% for major bleeding; 8.6% vs. 11.5% for clinically relevant nonmajor bleeding). Outcomes with apixaban and rivaroxaban were similar. Couturaud F et al.

  • Episode 373: 384. Chronic Kidney Disease and Empagliflozin Legacy Effect

    11/03/2025 Duración: 09min

    What Was Studied?The EMPA-KIDNEY trial followed 6,609 CKD patients at risk of disease progression. Participants were randomly assigned to receive empagliflozin (10 mg daily) or a placebo for a median of 2 years. After this ‘active’ phase, 4,891 patients entered a 2-year post-trial observational period where neither group received the trial drug, but doctors could prescribe open-label SGLT2 inhibitors. The goal? To see if empagliflozin’s benefits persisted after stopping treatment.Key Findings Sustained Kidney Protection:Over the entire 4-year period (active + post-trial), empagliflozin reduced the risk of kidney disease progression or cardiovascular death by 21% (HR 0.79). The number needed to treat (NNT) to prevent one event was 24 patients over 4 years. Post-Trial Benefits:Even after stopping the drug, the empagliflozin group saw a 13% lower risk of the primary outcome during the post-trial phase alone (HR 0.87). Specific Outcomes: Kidney disease progression: 23.5% (empagliflozin) vs. 27.1% (placebo).

    Metformin while not necessarily first line therapy for diabetes depending on the patients co-morbid conditions it is certainly highly ranked on the list of medications! I know often metformin is stopped while coming into the hospital for fear of potentially lactic acidosis or an increase in AKI with contrast studies however this ‘belief’ is largely based on myth and misconception. Metformin's contraindications should be contraindicated - PMC I also know that often metformin is held at discharge if the patients GFR is near or around 30 However, two new studies. Stopping Versus Continuing Metformin in Patients With Advanced CKD: A Nationwide Scottish Target Trial Emulation Study - ClinicalKey 4,278 Scottish residents with a diagnosis of type 2 diabetes were identified as prevalent metformin users with incident CKD stage 4.

    https://www.bmj.com/content/388/bmj-2024-081164systematic review and meta-analysis on prehabilitation before surgery, published in the BMJ in February 2025.Prehabilitation aims to prepare patients for surgery through interventions like exercise, nutrition, and psychological support. This study looked at which prehabilitation components are most effective for improving key outcomes after surgery.The researchers analyzed 186 randomized trials with over 15,000 participants. They used advanced statistical methods to compare different prehabilitation approaches.The key findings were: Exercise-only prehabilitation reduced complications by about 50% compared to usual care. Nutritional prehabilitation alone reduced complications by about 38%. Combining exercise, nutrition, and psychosocial support reduced complications by about 36%. For hospital length of stay, exercise plus psychosocial support was most effective, reducing stays by about 2.5 days on average. Multicomponent prehabilitation including exercise, nutriti

    https://jamanetwork.com/journals/jama/article-abstract/2828218DCIS is a non-invasive form of breast cancer, meaning the abnormal cells are contained within the milk ducts. For years, the standard treatment has been surgery, often followed by radiation and/or hormone therapy - the same treatments used for invasive breast cancer. But is this aggressive approach always necessary for low-risk DCIS?(Transition Music - Short and subtle - 2 seconds) Host: That's the question the COMET trial, or Comparing an Operation to Monitoring, With or Without Endocrine Therapy for Low-Risk DCIS, set out to answer. This large, randomized trial enrolled nearly 1000 women with newly diagnosed, low-risk DCIS across 100 centers in the US between 2017 and 2023. Participants were randomly assigned to either guideline-concordant care, meaning surgery with or without radiation, or active monitoring, involving regular check-ups with imaging and physical exams, reserving surgery only if the DCIS progressed to invasive cancer.

    Association of Duration of Recognized Hypertension and Stroke Risk: The REGARDS Study   (Transition Music - Short and subtle - 2 seconds)Host:  Hypertension is a well-known risk factor for stroke, but this study, led by Dr. George Howard and colleagues, asks a fascinating question: Does the duration of hypertension matter, even when blood pressure is managed? (Transition Music - Short and subtle - 2 seconds)Host: The researchers used data from the REGARDS study, a large, long-term study looking at racial and geographic differences in stroke. They followed over 27,000 stroke-free participants for over 12 years, tracking who developed stroke and how long they had been diagnosed with hypertension. Participants were grouped by duration of hypertension: normotensive (no hypertension), 5 years or less, 6 to 20 years, and 21 years or more. (Transition Music - Short and subtle - 2 seconds)Host:  So, what did they find? Several key findings emerged. First, people with longer durations of hypertension were taking more

    31/01/2025 Duración: 05min

    Is accelerated surgery for hip fracture better for high-risk patients? A recent substudy of the HIP ATTACK trial has shed new light on this topic. The original trial, published in 2020, compared accelerated surgery (within 6 hours) to standard-timing surgery (within 24 hours) for hip fracture patients. While the initial results showed only marginal benefits, this new analysis focuses on a specific group: patients with elevated cardiac troponin levels at hospital arrival--- THE SICK GUYS7.Here's what the researchers found:For patients with elevated troponin levels - about a quarter of those tested - accelerated surgery was associated with significantly lower mortality. The numbers are striking: 10% mortality in the accelerated surgery group compared to 23% in the standard surgery group. This translates to a number needed to treat of just 87.Interestingly, for patients with normal troponin levels, there was no significant difference in mortality between the two surgical approaches7.These findings suggest that f

  • Episode 362: 261. What to do with the beta blocker following a Myocardial Infarction

    15/01/2025 Duración: 06min

    Today, we're discussing two groundbreaking studies from 2024 that challenge our understanding of β-blocker therapy for secondary prevention after myocardial infarction, or MI.Let's start with a Swedish study Beta-Blockers after Myocardial Infarction and Preserved Ejection Fraction | New England Journal of Medicine that included over 5,000 patients with normal left ventricular ejection fraction after an MI5. The researchers compared long-term beta-blocker therapy with no beta-blocker treatment. Surprisingly, after 3.5 years, there was no significant difference in the primary endpoint of all-cause death or recurrent MI between the two groups5. This suggests that for patients with preserved heart function after an MI, long-term beta-blocker use may not provide additional benefits.  Now, let's turn to a French study involving 3,700 patients who were already on β-blockers following an MI Beta-Blocker Interruption or Continuation after Myocardial Infarction | New England Journal of Medicine7. This trial compared co

    13/01/2025 Duración: 10min

    Methods Monday  --- Accuracy of Event Rate and Effect Size Estimation in Major Cardiovascular Trials: A Systematic Review | Cardiology | JAMA Network Open | JAMA Network  During the design of a randomized clinical trial (RCT), estimation of the expected event rate and effect size is a key component to calculating the sample size. Overly optimistic estimation of event rates and effect sizes may lead to underpowered trials. If you expect 1 event per 100 people and you are looking for 5 events then you only need to enroll….. 500 people but if the actual event rate is 1 per 200 people then in order to get 5 events you need to enroll 1000 people!! You can see enrolling 500 people instead of 1000 would underpower your trial  This article, published in JAMA Network Open in April 2024, presents a systematic review of 344 contemporary cardiovascular randomized clinical trials (RCTs) to evaluate the accuracy of estimated event rates and effect sizes1. The key findings are:Event rates were frequently overestimated: Medi

    10/01/2025 Duración: 07min

    https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2821168A team of researchers set out to change that by developing a comprehensive algorithm.The process involved a multidisciplinary panel of 11 expertss with extensive experience in managing urinary retention. These experts evaluated about 100 clinical scenarios to create an initial flow sheet. The algorithm was then refined through interviews with 33 frontline clinicians from various specialties.So, what does this new algorithm recommend? Let's break it down:First, bladder scanning is the preferred method for evaluating patients with urinary retention symptoms. It's also recommended for asymptomatic patients who haven't voided in 3 hours.If a bladder scanner isn't available, the algorithm suggests using either an intermittent straight catheter (ISC) or an indwelling urinary catheter (IUC), with a preference for ISC initially.Now, let's talk about when to catheterize based on bladder scanner volumes. For symptomatic patients, catheterization is rec
