No, we can ’ t allow BAV to be a threat,.. to our heart-throb !
Interventional cardiologists generally do not believe (rather relish) in simple balloon dilatations to remove any vascular blocks. It is a mundane job for their talent-ridden hands. After conquering the coronaries, we made exclusive the valvular stents. No surprise, TAVR has taken over the aortic interventions with all its glamour and vigor, though it is definitely not an ideal choice in all. SCAI, the prestigious journal in Interventional cardiology has a recent article , that has a not-so pleasant message for TAVR lovers. PIIS2772930323004453Download It poses a direct challenge to cardiologists’ heart...

Handling Heat On Blood Pressure Medication: Your Summer Health Guide
Conclusion Summing it up, individuals taking blood pressure medication must be cautious during the hot weather season. Heat exposure can significantly impact blood pressure and may amplify the effects of medication, leading to potentially harmful health conditions. These risks, however, can be managed with the right precautions such as staying hydrated, dressing appropriately, and planning outdoor activities during cooler times of the day. Importantly, each person’s response to heat and medication varies. Hence, a one-size-fits-all approach isn’t ideal. Your healthcare provider is an invaluable resourc...

Blood Pressure Meds vs Blood Thinners: What ’ s The Difference?
Conclusion In conclusion, while blood pressure medicines and blood thinners are both crucial to heart health, their roles and mechanisms of action are notably distinct. Blood pressure medication works primarily on the vascular system, aiding in reducing blood pressure by relaxing blood vessels or altering the heart’s function. On the other hand, blood thinners target the blood itself, working to prevent the formation of potentially dangerous blood clots. Throughout this article, one thing becomes undeniably clear: the importance of regular consultations with your healthcare provider. When it comes to managing m...

Reviewing the all-in-pod heart health segment
BY ANISH KOKA The All-in podcast is a fairly popular show that features successful silicon valley investors commenting about everything worth commenting on from politics to health. The group has good chemistry and interesting insights that breaks the mold of the usual tribal politics that controls legacy media analysis of current events. Last week, the podcast touched on a topic I spend a fair amount of time on: Cardiology. Brad Gerstner, who is actually a guest host for this particular episode starts off by referencing something called Heartflow to evaluate the heart that has been recommended by one of the o...

Fight Aging! Newsletter, July 17th 2023
In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

Ultrahigh-Resolution Photon-counting CT Useful Prior to Transcatheter Aortic Valve Replacement
Assessment of coronary anatomy prior to Transcatheter Aortic Valve Replacement has great prognostic significance. Invasive coronary angiography is done prior to TAVR though CT coronary angiography has a role in ruling out coronary artery disease in those with low or intermediate pretest probabilities. Accurate interpretation of coronary arteries in those planned for TAVR has challenges because of high occurrence of abnormal heart rhythm, contraindications for beta blockers and nitroglycerine administraton. Still important is the blooming artifacts on CT coronary angiography in those with coronary stents or severe calcific...

Nocturnal Hypertension Unveiled: Protect Your Health While You Sleep
Is your blood pressure working the night shift? Let’s decode the mysteries of nocturnal hypertension together – from its symptoms and causes, to diagnosis and effective management. Sleep peacefully with our handy guide! Quick Summary Nocturnal Hypertension refers to high blood pressure that occurs at night, usually when blood pressure should naturally dip due to the circadian rhythm. Risk factors for nocturnal hypertension include conditions such as sleep apnea, diabetes, kidney disease, and lifestyle factors like high salt intake and lack of adequate sleep. Diagnosis and management of nocturna...

Intraoperative Imaging for Porcelain Aorta
Diffuse calcification of ascending aorta which may extend down is known as “Porcelain aorta”. Intraoperative epiaortic  echocardiography along with manual palpation during surgery has been described as the most sensitive technique for detecting ascending aortic atheroma and calcification [1]. A prospective study evaluated this in hundred consecutive patients undergoing coronary bypass or valve surgery [2]. Ascending aorta was assessed by manual palpation by the operating surgeon, intraoperative transesophageal echocardiography and epiaortic ultrasound using linear and phased-array imaging. No difference was noted...

A woman in her 20s with syncope
Written by Destiny Folk MD, with edits by Meyers, peer reviewed by Smith and GrauerA woman in her late 20s with a past medical history of cervical cancer status post chemotherapy and radiation therapy presented to the emergency department for shortness of breath, chest tightness, and two episodes of syncope.Her initial vital signs revealed a temp of 97.7F, HR 125, RR 20, BP 115/90, and an oxygen saturation of 95% on room air. Upon arrival, she did not appear in acute distress. She was noted to be tachycardic and her heart sounds were distant on physical exam. She had a normal respiratory effort, and her lungs were clear to...

Which chemotherapeutic agent is well known to cause coronary vasospasm?
5-fluorouracil is well known to cause coronary vasospasm. 5-fluorouracil and its orally active prodrug capecitabine are fluoropyrimidines, belonging to the class of antimetabolites used for treatment of malignancies of breast, head and neck tumours and gastrointestinal tumours. Mechanisms for coronary vasospasm Endothelial cell damage with cytolysis and denudation Increased endothelin-1 bioactivity leading to vasoconstriction When high dose infusions are given, coronary vasospasm with angina, arrhythmia or even sudden death can occur in up to 5% of patients. Vascular toxicity occurs generally within 72 hours of the...

Single chamber or dual chamber pacemaker? Cardiology Basics
The decision between single chamber and dual chamber pacemaker though important based on cost, device longevity and complication wise, is not that easy to make. I am trying to summarize based on the 2018 American College of Cardiology/American Heart Association/Heart Rhythm Society guidelines on this aspect [1]. In underprivileged regions, given an option, there is always a potential bias towards single chamber devices as they are cheaper, tend to have more battery life, easier to implant and likely to have lesser procedure and lead related issues. In symptomatic sinus node dysfunction, with correlation between symptoms a...

What is inappropriate sinus tachycardia? Cardiology Basics
Inappropriate sinus tachycardia (IST) is sinus tachycardia inappropriate to the situation. It is defined as sinus rates above 100 beats per minute at rest or average sinus rate above 90 beats per minute over 24 hours without an underlying cause. Important secondary causes of sinus tachycardia like the use of caffeine, alcohol, nicotine, drugs of abuse like cocaine, increased function of thyroid gland, fever, anxiety, pain, and other illnesses which can increase the heart rate have to be excluded before considering IST. IST may be either asymptomatic or sometimes associated with palpitation, shortness of breath, near synco...

What is coronary calcium scoring? Cardiology Basics
Coronary calcium scoring is done from a plain multidetector computed tomography (CT) scan. MDCT produces images of coronary arteries in multiple thin slices. Calcium deposits in plaques within the coronary arteries can be found from these images. Calcium deposits occur within atherosclerotic lesions inside the coronary arteries. Some of these plaques can rupture later and lead to clot formation and total occlusion causing acute myocardial infarction. Coronary calcium scoring can be done as an outpatient test from the X-ray department. As no contrast medium is injected, there is no risk of allergic reactions unlike CT coro...
