Six-Lead, Consumer-Facing ECG Device Close to Release to Market
I have previously blogged aboutAliveCor's three-lead ECG device in particular and cardiology in general as examples of cardiology being a"collision point" between consumer IT and the healthcare system (see:Three New Studies Confirm Clinical Utility of AliveCor ’s KardiaMobile Device and AI Algorithms;Cardiology as a"Collision Point" between Consumer IT and the Healthcare System). The company is now testing a a six-lead ECG instrument (see:AliveCor previews next product: A 6-lead smartphone ECG). Here is an excerpt from this article:AliveCor, which has offered an smartphone-connected ECG sinc...

Fight Aging! Newsletter, May 6th 2019
This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an ass...

TAVR: Aortic valve replacement without open-heart surgery
There has been a flurry of news recently about a procedure called trans-catheter aortic valve replacement (TAVR) for the treatment of the common heart condition aortic stenosis (AS). You may even know people who have had this procedure performed. What exactly is TAVR? And what’s all the excitement about? What is aortic stenosis? First, it’s important to understand the condition that TAVR is designed to treat, aortic stenosis. The aortic valve is the last structure of the heart through which blood passes before entering the aorta and circulating throughout the body. The aortic valve has three flaps, called leaflets, tha...

Is this terminal QRS distortion? Is there LVH?
This ECG of a patient was sent to me with the question, " Just LVH, no? "What do you think?First, is there Terminal QRS distortion?  We defined terminal QRS distortion as absence of BOTH a J-wave and S-wave in EITHER of V2 or V3, and found that zero of 171 patients with normal variant ST elevation in V2-V4 had this finding.  In other words, it is veryspecific for LAD occlusion (vs. early repol), though not sensitive.  We found that there was an S-wave in V2 100%, and an S-wave in V3 in 90%.  In the 10% that had no S-wave in V3, all had a J-wave of at least 0.5 mm.This ECG has no S-wave in V3, but it has...

Implantable STEMI monitor
AngelMed Guardian system (Angel Medical Systems, Eatontown, New Jersey) is an implantable device which detects ischemic events using a pacemaker lead positioned at right ventricular apex [1]. The device detects ischemic events by analyzing shifts in ST segment. It compares ST deviation of a 10 second electrogram with baseline data. If the shift in ST segment is greater than the heart rate dependent programmable threshold, an emergency alert signal is generated. The implantable device gives a vibratory alert and an external associated device gives auditory and visual alert. ALERTS (AngelMed for Early Recognition and Treat...

Canagliflozin protects Heart and Kidneys – CREDENCE Trial
Canagliflozin protects Heart and Kidneys – CREDENCE Trial Canagliflozin is sodium–glucose cotransporter 2 (SGLT2) inhibitor used in the treatment of type 2 diabetes mellitus. CREDENCE Trial [1] has shown that Canagliflozin provides both cardiovascular and renal protection in patients with type 2 diabetes mellitus. CREDENCE (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) trial was a double blind randomized trial comparing Canagliflozin 100 mg daily with placebo in type 2 diabetes with albuminuria and chronic kidney disease. They were also treated with renin–angiotensin...

Reducing residual cardiovascular risk
Reducing residual cardiovascular risk in patients treated with statins and having hypertriglyceridemia was addressed by Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial (REDUCE-IT) [1]. REDUCE-IT was a double blind placebo controlled multicenter randomized trial. Patients with established cardiovascular disease or diabetes mellitus with other risk factors treated with statins were evaluated. At study inclusion they needed to have fasting triglyceride levels between 135 and 499 mg/dL and LDL cholesterol level 41 to 100 mg/dL. They were randomized to either 2 g of icosapent ethyl twice daily or...

What happens when a patient with LAD OMI does not go immediately to the cath lab?
This patient was extremely elderly, and although the diagnosis was recognized, she did not go to the cath lab for reasons related to age and patient/family choice.Nevertheless, there is a lot to learn from the ECGs.I was shown this ECG without any information:QTc = 431 msWhat was my response?I immediately said:" Acute LAD occlusion. OcclusionMI (OMI) "  (And sinus rhythm with a PVC.) (Not quite a STEMI, but same effect.)Why did I diagnose LAD occlusion?There isST elevation in V2-V4 that does not quite meet " STEMI criteria. "  Is it normal ST elevation?  No!  How do I know?  First, there is re...
