Gardner Treadmill Protocol Gardner Treadmill Protocol, also known as Gardner-Skinner Protocol was described in 1991 [1]. It is used mainly in the evaluation of peripheral arterial disease. The seminal article evaluated the effect of handrail support on claudication distance. Handrail support reduces energy cost of treadmill walking, and can affect claudication distance and hemodynamic responses in persons with peripheral vascular disease.
By Magnus Nossen, from Norway I was shown this print out of a rhythm strip from a patient on telemetry. I was asked what's going on? There are four leads shown (II, dV2, V1 and V5). The three images beneath one and other are consecutive rhythm strips each 10 seconds long. The patient was on telemetry due to acute MI. Can you correctly describe what's going on in this interesting rhythm strip?
Running a successful cardiology clinic involves more than providing top-notch patient care. Managing the financial aspect of your practice efficiently is equally crucial. Electronic Health Record (EHR) systems, designed explicitly for cardiology clinics, can significantly enhance your clinic’s Revenue Cycle Management (RCM) and improve Return on Investment (ROI).

Objective To assess gender, ethnicity, and deprivation-based differences in provision of aortic valve replacement (AVR) in England for adults with aortic stenosis (AS). Methods We retrospectively identified adults with AS from the English Hospital Episode Statistics (HES) between April 2016 and March 2019 and those who subsequently had an AVR. We separately used HES-linked Clinical Practice Research Datalink (CPRD) to identify people with AVR and evaluate the timeliness of their procedure (CPRD-
Even if you live a long life with your physical and cognitive capacities intact, you still have to choose ‘ How ’ to live your life. For me, the only reason I wish to live a long life at a high quality is that I get more time and capacity to do what I believe my life was intended for. This is the domain of soul span: What will you do with the time allotted to you?
What is the infarct artery? I usually don't ask this question, as it is rarely relevant to the decision to activate the cath lab. This is one case where it made a difference: Right Ventricular MI seen on ECG helps Angiographer to find Culprit Lesion Nevertheless, it is sometimes a fun academic exercise to try to predict the infarct artery: An elderly patient had onset of chest pain one hour prior.
Hypertension, Volume 80, Issue 12 , Page 2495-2500, December 1, 2023. There are mounting data that at least 30% of hypertensives who are appropriately screened have primary aldosteronism (PA), rather than the commonly reported figure of 5% to 10%. Second, there are similar data that undertreated patients with PA have a 3-fold higher risk profile than essential hypertensives with the same blood pressure levels.
Objective To determine the diagnostic yield of a ‘high’ N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with suspected heart failure (HF) referred from primary to secondary care. Methods In this retrospective study, cardiac diagnoses were quantified in consecutive patients with an NT-proBNP>400 ng/L referred from primary care centres to a specialist HF service.
This July, thousands of you said that you wanted me to produce a course that would synthesise best practices for: Understanding heart disease. Assessing your risk. Maximally reducing that risk. Thousands of you completed a questionnaire addressing your objectives and obstacles in addressing cardiovascular risk. Although there were many and varied responses, the primary message was that most of you: Are concerned about your future risk of heart disease because of a risk factor or family history o
The remote monitoring process for cardiac implantable electronic devices is evolving, creating challenges for staff and patient compliance. Current standards of care for remote monitoring require a modernized and structured process to keep in compliance. Pediatric populations have unique issues to consider.
Hypertension, Volume 80, Issue 12 , Page 2621-2626, December 1, 2023. BACKGROUND:Circadian rhythm regulates many important biological functions in humans. The goal of this study is to explore the impact of day-to-day deviations in the sleep-wake cycle on nighttime blood pressure (BP) dipping and further examine whether the ethnic difference in day-to-day deviations in sleep patterns can explain the ethnic difference in nighttime BP dipping.METHODS:Twenty-four-hour ambulatory BP monitoring and 7-
Introduction Atrial fibrillation (AF) is associated with a fivefold increased risk of stroke. Oral anticoagulation reduces the risk of stroke, but AF is elusive. A machine learning algorithm (Future Innovations in Novel Detection of Atrial Fibrillation (FIND-AF)) developed to predict incident AF within 6 months using data in primary care electronic health records (EHRs) could be used to guide AF screening.
Researchers play ultra-brief tones to stimulate the brain during deep sleep. This stimulation improves cardiac output and relaxation of the left ventricle. Such technology to improve cardiovascular function could be relevant both in disease treatment and competitive sports.
Hypertension, Volume 80, Issue 12 , Page 2650-2664, December 1, 2023. BACKGROUND:Inflammation plays a critical role in the development of hypertension and vascular remodeling. Resolvin E1 (RvE1), as one of the specialized proresolving lipid mediators, promotes inflammation resolution by binding with a G protein-coupled receptor, ChemR23 (chemerin receptor 23).
We aimed to investigate differences in tissue temperature characteristics during radiofrequency ablation using three catheters, commonly employed in the 50 W high-power short-duration (HPSD) setting and a 90 W/4 s very HPSD setting catheter. We identified temperature variations across the four ablation settings and their association with collateral damage, including injuries to the esophagus and phrenic nerve.
This paper reviews the literature on image-guided cardiac resynchronization therapy (CRT) studies. Improved outcome to CRT has been associated with the placement of an LV lead in the latest activated segment free from scar. The majority of randomized clinical trials investigating a guided LV lead implantation did not show superiority over conventional implantation approaches.
In this study, two independent cohorts were used to investigate for cardiovascular magnetic resonance (CMR) and genetic features of dilated cardiomyopathy (DCM) in individuals with coronary artery disease (CAD). First, the UK Biobank was used to assess for the association between rare variants in DCM-associated genes, phenotype and outcomes in participants with CAD.
Circulation, Ahead of Print. BACKGROUND:We investigated the usefulness of invasive coronary function testing to diagnose the cause of angina in patients with no obstructive coronary arteries.METHODS:Outpatients referred for coronary computed tomography angiography in 3 hospitals in the United Kingdom were prospectively screened. After coronary computed tomography angiography, patients with unobstructed coronary arteries, and who consented, underwent invasive endotyping.
Abstract Aims Patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF) are often treated with calcium channel blockers (CCBs), although the safety of CCBs in these patients is uncertain. We aimed to investigate the association between CCB use and clinical outcomes in patients with HFmrEF/HFpEF; CCBs were examined overall, as well as by subtype (dihydropyridine and non-dihydropyridine).
Hypertension, Ahead of Print. Background:Cigarette smoking/nicotine exposure in pregnancy shows an increased risk of hypertension in offspring, but the mechanisms are unclear. This study tested the hypothesis that m6A RNA hypomethylation epigenetically regulates vascular NOX (NADPH oxidase) and reactive oxygen species production, contributing to the fetal programming of a hypertensive phenotype in nicotine-exposed offspring.Methods:Pregnant rats were exposed to episodic chronic intermittent nico

Proportion of patients with 0, 1, 2 and ≥3 NCCs and the prevalence of each individual comorbidity ( A ). Average percentage of the optimal doses of GDMTs by number of NCCs ( B ).
Hypertension, Volume 80, Issue 12 , Page 2627-2640, December 1, 2023. BACKGROUND:Endothelial dysfunction plays a crucial role in aortic remodeling. Aerobic glycolysis and endothelial-to-mesenchymal transition (EndoMT) have, respectively, been suggested to contribute to endothelial dysfunction in many cardiovascular diseases. Here, we tested the hypothesis that glycolytic reprogramming is critical for EndoMT induction in aortic remodeling through an epigenetic mechanism mediated by a transcriptio
An individual diagnosed with type 2 diabetes at age 30 years could see their life expectancy fall by as much as 14 years, an international team of researchers has warned. Even people who do not develop the condition until later in life – with a diagnosis at age 50 years – could see their life expectancy fall by up to six years, an analysis of data from 19 high-income countries found.

People looking to reduce their cholesterol and trim fat from around their waist could try swapping meat for Quorn protein, according to the findings from a new study, which saw positive effects in both areas in just two weeks.
Pulmonary vein isolation (PVI) remains the cornerstone of atrial fibrillation (AF) ablation. In patients with more advanced AF subtypes, atypical atrial flutter, and extensive atrial myopathy, additional linear ablation is often required; however, durable block of these remains challenging. Gardziejczyk et al ([link] shared a case of a 61-year-old patient with recurrent symptomatic persistent AF despite 2 prior ablation attempts and confirmed PVI and posterior wall isolation.
