Pop-Up Sensors Measure Electronic Signals in Cardiac Cells
Researchers at University of California San Diego have developed a tiny ‘pop-up’ sensor that can measure the electronic signals propagating inside cardiac cells. The technology consists of tiny spike-like protrusions that can penetrate cell membr...

A Reminder that Merely Elevated Blood Pressure Still Increases Cardiovascular Disease Risk
The old guidelines for systolic blood pressure drew the line for increased risk of cardiovascular disease at 140 mmHg, with higher systolic blood pressure defined as hypertension. That dividing line was then moved down to 130 mmHg. In the past few years, further evidence has shown that elevated systolic blood pressure of 120 mmHg or above still produces increased risk, and that one shouldn't feel comfortable and safe in the 120-129 mmHg range. The risk of cardiovascular disease scales up with increasing blood pressure, and as noted here, also with the modern lifestyle choices leading to excess fat tissue, metabolic disease...

MDM of mitral stenosis is a “ mid diastolic misnomer ”
Nearly a century ago, Carl Wiggers helped us understand the dynamics of cardiac cycle with a historical diagram depicting systole and diastole. We know diastole has 4 phases. They are  IVRT(nil)  early rapid filling,(70%) diastasis,(0-5%) atrial contraction(25%) (Percentage filling within the brackets) What is mid diastole? The easiest way to define mid diastole is to divide diastole into three parts with reference to time and call the mid-third as mid-diastole. (.5 seconds/ divided by 3). But, Physiologically we can’t do that. Even hemodynamically there is no distinct mid diastole as diastole is di...

Measuring Gene Expression Changes in the Brain as a Result of Heart Failure
Heart failure causes harm to the brain by reducing the supply of blood, and thus the supply vital nutrients and oxygen, to brain cells. The precise details of how this leads to cognitive decline are yet to be fully mapped. Researchers here assess changes in gene expression the brains of mice suffering from heart failure, as a starting point for further investigation of specific mechanisms. The best path forward for this class of contribution to neurodegenerative conditions is to prevent or reverse vascular aging, which has numerous components. There is the narrowing of blood vessels via atherosclerosis; the failure of smoo...

HARPOON System for Mitral Valve Repair: Interview with Daveen Chopra, Edwards Lifesciences
Degenerative mitral regurgitation occurs when the mitral valve prolapses, causing blood to leak back into the atrium every time the heart beats. The condition can be asymptomatic for many people, but for some it can cause a variety of issues, includi...

Deeper Worries in America
I worry about the coronavirus. It’s already killed more than 100,000 Americans. The recent protests have created a nerve-wracking public-health situation for the next weeks. I really worry about racism. Not only racism in police systems but more systemic racism in our culture. My friend Dr. Andrew Foy sent me this slide and post showing the large disparity in black and hispanic representation in medical education. There can be no rest so long as a man like Dr. Otis Brawley, a distinguished professor of medicine, “can get thrown to the ground, handcuffed and questioned at gunpoint for looking ...

Link between LV dysfunction & VPDs … Is it a cause or bcoz ?
We know, LV dysfunction of any etiology can cause VPDs.This must be differentiated from VPDs induced LV dysfunction. Mind you, this is not an easy job at all. When do you suspect excess VPDs are the cause (or might cause) of LV dysfunction?In young, otherwise healthy persons with “VPDs and LV dysfunction”  would suggest chronic abnormal electrical activity is the cause for subsequent LV dysfunction. (An expression of electromechanical remodeling) Monomorphic VPDs more often suggest primary electrical pathology(Like OTVT, Fascicular VT)VPD count more than >10000 in 24 hrs in Holter will probably I...

COVID-19: The Nursing Home Tragedy
By ANISH KOKA, MD Our strategy with nursing homes in the midst of the current pandemic is bad.  Nursing homes and other long term care facilities house some of our sickest patients in and it is apparent we have no cogent strategy to protect them.  I attempted to reassure an anxious nursing home resident a few weeks ago. I told him that it appeared for now that the community level transmission in Philadelphia was low, and that I was optimistic we could keep residents safe with simple maneuvers like better hand hygiene, restricting visitors, as well as stricter policies with regards to keeping caregivers wit...

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 patient with abdominal pain associated with alcohol withdrawal and alcoholic ketoacidosis
While at work, one my partners showed me this ECG of a 50-something woman with abdominal pain associated with alcohol withdrawal and alcoholic ketoacidosis.  There was no reported chest pain or SOB.What do you think?I said it " looks like takotsubo.  Electrolytes might contribute.  Are they back yet? (they were not).  I do not think this is a coronary event. "He asked why.I responded: " bizarre T-waves, with T-wave inversion and extremely long QT.  The computer measures the QT at 506 ms, but it really is more like 560-580 ms, with a QTc of 600-620 ms.  This is not at all typical of ACS but ver...

9 Things Every Healthcare Startup Should Know About Business Development
By ANDY MYCHKOVSKY In this post, I write down all my strategy and business development knowledge in healthcare and organize it into the top 9 commandments for selling as a healthcare startup. I think everyone from the founder to the most junior person on the team should know these pillars because all startups must grow. I should also note these tenets are most applicable for selling into large enterprise healthcare incumbents (e.g., payers, providers, medical device, drug companies). Although I appreciate the direct-to-consumer game, these slices are less applicable for that domain. If your startup needs help developing...

Let ’s Put The Best To The Test: Our KardiaMobile6L Review
AliveCor is close to our hearts. Literally. David Albert, the co-founder of the company, started experimenting with handheld, wireless ECG devices in the late 90s. Approximately 10 years later we tried out their FDA-cleared, medical grade gadget. It was a truly inspiring moment. Needless to say, we’ve been keeping track of their journey ever since. In our eyes Kardia is the textbook example of technology shaping health care, empowering and supporting not only e-patients, but medical professionals as well. So, let’s take a look at their newest creation, the KardiaMobile6L! Why did the chicken cross the road? T...
