What causes heart failure with preserved ejection fraction (HFpEF)?
Heart failure with preserved ejection fraction (HFpEF) is a multifactorial and multisystemic disorder that represents more than 50% of all heart failure cases.[1] Epidemiologic data from the Framingham Study, an international cohort study, shows a rapid increase in the prevalence of HFpEF over the past three decades, from 41% to 56% and, conversely, a decrease in the prevalence of HFrEF from 44% ...

Diagnosing heart failure with preserved ejection fraction (HFpEF)
Heart failure with preserved ejection fraction (HFpEF) has recently been recognized as the single greatest unmet need in cardiovascular medicine, overtaking heart failure with reduced ejection fraction (HFrEF) and becoming the most common form of heart failure, with a prevalence that is increasing by 1% annually.[1] Despite this, there remains no gold standard in diagnosing HFpEF. Diagnosing ...

What is heart failure with preserved ejection fraction (HFpEF)?
Overview What is HFpEF? Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure, despite normal or near-normal LV ejection fraction (EF). Most patients with HFpEF also display normal LV volumes and an abnormal diastolic filling pattern (i.e, diastolic ...

Emerging therapy for HFpEF: SGLT2 inhibitors
Recent clinical trials investigating sodium-glucose cotransporter 2 inhibitors (SGLT2i) have highlighted that this drug is highly effective in treating patients with heart failure with preserved ejection fraction (HFpEF). HFpEF is a complex disease which accounts for more than half of all heart failure (HF) hospital admissions and is an increasing disease burden. [1] The prevalence of HFpEF is ...

A Contemporary Review of ST-Elevation Myocardial Infarction: Pathophysiology, treatment options and hot topics
Pathophysiology, treatment options and hot topics Improvements In Stemi Treatment The immediate and long-term prognosis of patients experiencing an ST segment elevation myocardial infarction (STEMI) has changed dramatically since the introduction of coronary reperfusion therapies during primary percutaneous coronary intervention (pPCI). The evolution of these therapies accelerated with the ...

Atrial Flutter - Typical Atrial Flutter (AFL) - Case Study
Typical Atrial Flutter (AFL) is the most common type of atrial flutter and is a macro-reentrant right atrial tachycardia that uses the cavo-tricuspid isthmus as an essential part of a counter-clockwise circuit. The tendon of Todaro, the crista terminalis, the inferior vena cava, the tricuspid valve annulus, and the coronary sinus os provide anatomical landmarks of the circuit. Typical AFL can be ...

Arrhythmia - Atrial Fibrillation (AF)- Case Study
Atrial Fibrillation (AF) is often described as an irregularly irregular rhythm. AF is an arrhythmia with no consistent ventricular response or pattern due to its somewhat random and chaotic discharging of atrial impulses firing disconnectedly from multiple foci. This continuous and erratic behavior results in a ventricular response that changes from beat to beat. AF will typically present with a ...

Worldwide Prevalence of Atrial Fibrillation
The prevalence of Atrial Fibrillation globally is rising at a significant rate. However, researchers, scientists and clinicians remain uncertain as to how many people may have the heart irregularity because of this rapid growth. In addition, there are concerns that because of the COVID-19 pandemic, there may be millions of people worldwide with Atrial Fibrillation (AF) who have not been ...

The Symptoms of Atrial Fibrillation
An array of symptoms can suggest the presence of the common heart irregularity Atrial Fibrillation. While it affects millions of people worldwide, it is also widely acknowledged that Atrial Fibrillation (AF) can be a condition that is relatively difficult to diagnose as the symptoms can be intermittent. Traditionally, AF is diagnosed by a physician checking the patient’s pulse, but ...

The Evolutional Technology of a Modern Heart Rate Monitor
The technology behind a modern heart rate monitor is a true testament to how medical science has evolved. Heart rate monitors today are not only used for tracking cardiovascular functions in hospital settings but also used as a tool for health and fitness training. They measure and display information in real-time so that medical professionals can make accurate assessments of the patient. In ...

The evolution of photoplethysmography (PPG) within smart devices
As a technology, photoplethysmography (PPG) has been explored for almost a century, but it is only in the last few years that it has had a broader application beyond specialised medical settings. That has generally been driven by the evolution of smartphones, smartwatches and even smaller wearable devices such as smart rings. PPG is most commonly used in pulse oximetry in clinical settings ...

What is Atrial Fibrillation?
Atrial Fibrillation (AF) is a cardiac condition that affects millions of people worldwide. Characterized by a rapid, irregular heartbeat or arrhythmia, it can potentially lead to other serious conditions and also increase the risk of stroke in patients who have AF. It is estimated that there are currently some 4.5 million confirmed cases of AF in the European Union and more than 2.3 million ...

Usage of Smart Device in the Healthcare Industry
A smart device in the 21st century is an essential tool that bridges the gap between humans no matter where they are in the world. With the constant evolution of technology, we are now able to build a connection and socialise in astonishing ways we would have never imagined decades ago. Though mobile phones are the most common smart devices that people are aware of, modern technology is ...

Smartwatch blood pressure sensor technology is getting close
Blood pressure tracking capabilities on Apple Watches have been a long-awaited feature, and the technology to make it happen appears to be in the works. The sensor-making company Apple partners with for its smartwatch sensors, Rockley Photonics, recently announced that initial tests of its photonics-based sensor could measure blood pressure non-invasively when worn on the wrist. ...

First-in-man demonstration of 18-month spatiotemporal stability of active atrial fibrillation source detected by Electrographic Flow mapping in persistent atrial fibrillation
Keywords: atrial fibrillation, catheter ablation, mapping, atrial fibrillation, source, electrographic flow Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue. The aim of this ...

Functional Electrographic Flow Patterns in Patients with Persistent Atrial Fibrillation Predict Outcome of Catheter Ablation
Aims: Electrographic flow (EGF) mapping is a method to detect action potential sources within the atria. In a double-blinded retrospective study we evaluated whether sources detected by EGF are related to procedural outcome. Methods: EGF maps were retrospectively generated using the Ablamap® software from unipolar data recorded with a 64-pole basket catheter from patients who previously ...

Noise Pollution and Mental Health
Living or working in continual loud noise can be annoying – but did you know it’s bad for your mental health too? Whether you live next to a busy main road, with the constant hum of traffic, or you work in a noisy factory; excess noise can negatively impact your wellbeing. It can make you feel stressed and annoyed and it can also cause a lack of sleep, especially if it goes on for 24 ...

Comparing phase and electrographic flow mapping for persistent atrial fibrillation
Background: An increasing number of methods are being used to map atrial fibrillation (AF), yet the sensitivity of identifying potential localized AF sources of these novel methods are unclear. Here, we report a comparison of two approaches to map AF based upon (1) electrographic flow mapping and (2) phase mapping in a multicenter registry of patients in whom ablation terminated persistent ...
