A man in his 70s with weakness and syncope
DiscussionBrugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. Patients that develop a Type 1 pattern without any precipitating or provoking factors have a risk of SCD of 0.5-0.8% per year. In patients that only have this pattern induced by a sodium channel blocking agent have a lower rate of SCD (0 - 0.35% per year)[1]. Drugs that have been associated with Brugada ECG patterns include tricyclic antidepressants, anesthetics, cocaine, methadone, antihistamines, electrolyte derangements, and even tramadol. [2]. Our patient had a Brugada Type ...

Pulmonary Arterial Hypertension: Unraveling Its Impact On Heart And Lungs
Conclusion Navigating the complexities of Pulmonary Arterial Hypertension (PAH) might seem daunting. However, with the right knowledge and proactive approach, it’s possible to manage the condition and maintain a good quality of life. PAH, a unique type of high blood pressure affecting the arteries in the lungs, can put extra strain on the heart. Over time, this can lead to heart failure. The condition’s root cause may vary, from genetic factors to other health issues like heart defects, liver disease, or autoimmune diseases. Remember, sometimes the cause remains unknown, resulting in idiopathic pulmonary ...

Hackers, Breaches And The Value Of Health Data: 2022 E-Book Update
As solutions like remote care are becoming the norm, 3D printing disrupts the normal supply chain and the number of life science studies on tools like artificial intelligence (A.I.) skyrocket, it’s become clear that we are not anticipating the digital health era; we are in the digital health era. This was to come sooner or later, but the pandemic accelerated the process by years. However, along with the enhanced healthcare landscape that digital health brings along, there is the pressing issue of privacy. To put it bluntly, there is no digital health without sacrificing a part of our privacy. The advanced techno...

Vaccine associated myocarditis revisited with COVID-19 mRNA vaccines
When I had reviewed the topic of vaccine associated myocarditis for an editorial in the BMH Medical Journal in 2017, most of the cases were associated with small pox vaccination [1]. There were also reports of streptococcal pneumonia vaccine and influenza vaccine associated myocarditis. Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) used in the vaccine were also implicated in some cases [2,3]. While the large scale vaccination for small pox in an attempt to prepare for potential bioterrorism was the association in 2003 [4], COVID-19 mRNA vaccines are currently in the limelight for vaccine induced myocarditis...

Considering the Ethics of Extending the Healthy Human Life Span
To suffer or become incapacitated is to diminish the utility of being alive. The way to minimize this loss is to work towards removing the causes of suffering and incapacitation. The greatest such causes are medical, and of those, aging is by far the largest. Similarly, to die is to suffer the loss of all that one might have been and done after that time. It is a tragedy that any individual ceases to exist. The way to minimize this loss is to work to remove the causes of death. The greatest such causes are medical, and of those, aging is by far the largest. Ethically, the case for working to extend healthy human life spans...

Your Privacy In The Digital Health Era: The Medical Futurist ’s Guide
As solutions like remote care are becoming the norm, 3D-printing disrupts the normal supply chain and even the number of life science studies on tools like artificial intelligence (A.I.) skyrocket, it’s become clear that we are not anticipating the digital health era; we are in the digital health era due to the COVID-19 pandemic.  First and foremost, it’s an era defined by a cultural transformation that will upend the traditional structure of healthcare. Clinical-grade sensors are available outside of the ivory towers of medicine; patients demand such tools so that they can become more proactive in managing the...

Fight Aging! Newsletter, April 13th 2020
This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...

How does cardiovascular disease increase the risk of severe illness and death from COVID-19?
Based on reports from China, we know that most COVID-19 patients (about 80%) will develop mild flulike symptoms, including fever, dry cough, and body aches that can be managed at home. 20% will develop more serious symptoms, such as pneumonia requiring hospitalization, with about a quarter of these requiring ICU-level care. Initial reports focused on the respiratory effects of COVID-19, such as pneumonia and difficulty breathing. But more recent literature has described serious cardiovascular complications occurring in about 10% to 20% of hospitalized patients. Someone with pre-existing heart disease who becomes ill with C...

A young F is hyperthermic, delirious, and dry: Fever-induced Brugada? Diphenhydramine toxicity? Tricyclic?
Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients. Patients with known fever-triggered Brugada syndrome should be surveilled closely during fever and be started on antipyretic therapy as soon as possible.  There are limited data regarding the impact of EP study in BrS patients triggered by fever.  An EP study might be helpful in symptomatic patients (Sroubek et al., 2016) in the presence of spontaneous BrS ECG or drug-induced ECG.The prognostic significance of fever-induced Brugada syndrome.  Heart Rhythm 2016.Eighty-eight asymptomatic patient...

Electrocardiographic measures of ventricular repolarization
Brief Review Abstract: Electrocardiographic measures of ventricular repolarization include QT dispersion, T wave width, spatial QRS-T angle and T peak to T end interval. Following parameters have been used as electrocardiographic measures of ventricular repolarization: QT variation between different ECG leads (QT dispersion) T peak to T end interval (Tp-Te) T wave width Spatial angle between QRS and T vectors QT dispersion Difference in QT interval between the surface electrocardiographic leads is known as QT dispersion. QT dispersion can be defined as the difference between the maximum and minimum QT intervals on bod...
