Heart failure in chronic kidney disease – Cardiology Basics
Heart failure in chronic kidney disease – Cardiology Basics
Prevalence of both heart failure and chronic kidney disease (CKD) are increasing as the population is aging globally. Hence heart failure in chronic kidney disease is seen more often. Presence of CKD in heart failure increases morbidity and mortality. Though there is increasing use of effective medications and special devices like cardiac resynchronization therapy in heart failure patients in general, those with CKD have not been benefited well.
CKD is defined as abnormalities of kidney structure or function, present for >3 months, with implications for h...

What is a wearable cardioverter defibrillator (WCD)? Cardiology Basics
Wearable cardioverter defibrillator (WCD) is a device which is worn on a vest, monitors the heart rhythm continuously and delivers a defibrillator shock in case of life threatening ventricular arrhythmias. Implantable cardioverter defibrillator (ICD) is a similar device which is implanted subcutaneously for long term use. WCD is meant for temporary use for those who have a high risk of life threatening ventricular arrhythmias but are ineligible for an ICD implantation as per the guidelines.
WCD has patch electrodes for giving the shocks and a monitoring system built-in into a vest while the defibrillator with battery is w...

How is pulmonary embolism treated? Cardiology Basics
Pulmonary embolism is obstruction of pulmonary arteries due to emboli migrating from other parts of the body. It is a potentially life threatening condition if a major branch or multiple branches are obstructed. More emboli can travel to the lungs from the original source and hence pulmonary embolism may worsen later even if the initial episode involves only a small portion of the lungs. So, it is important to treat pulmonary embolism even if it is mild. Treatment options will depend on the severity of the situation.
Initial treatment will be with parenteral anticoagulants like heparin or low molecular weight heparin. Aft...

What are the precautions for undergoing a treadmill test (TMT)? Cardiology Basics
Treadmill exercise test is often taken as a fitness test during routine medical check-up. TMT is also done for evaluation of a case of suspected coronary artery disease and as part of post myocardial infarction evaluation. TMT in children is often for the evaluation of arrhythmic disorders. But this is not a test meant for everyone coming for a health check-up. A preliminary assessment of the fitness of an individual to undergo a treadmill test (TMT) is desirable.
This will include a short check on whether the person has any medical conditions which could increase the risk of the test. Moreover, it is difficult for person...

What is thrombolytic therapy for myocardial infarction? Cardiology Basics
Thrombolytic therapy used to be an important mode of early treatment of acute myocardial infarction. Though it has been largely superseded by primary angioplasty, thrombolytic therapy may still be useful in certain situations. It is still an important form of treatment in resource limited locations.
Myocardial infarction is usually due to sudden occlusion of a coronary artery by thrombus formation on a pre-existing partial obstruction by an atherosclerotic plaque. Plaque rupture with local thrombus formation is the usual mechanism. Dissolving the thrombus soon after the occurrence of a myocardial infarction can salv...

What are the dangerous signs on Holter monitoring? Cardiology Basics
Holter monitoring is an ambulatory ECG monitoring, usually with a digital recorder, attached to a belt, typically for 24 to 48 hours. Two or three channels are usually recorded with an appropriate number of patch electrodes attached to the chest. Holter monitoring is usually done when a cardiac arrhythmia as the cause of symptoms is suspected. It can also be done to detect atrial fibrillation as part of post stroke workup.
Dangerous signs to look for on a Holter tracing are life threatening tachy and bradyarrhythmias. Here is a long pause which could cause syncope. This is a long sinus pause in sick sinus syndrome. Sympto...

What is a myocardial bridge? Cardiology Basics
Normally the coronary arteries are located outside the myocardium. Occasionally a segment of the coronary artery passes through the myocardium. This causes a narrowing of that region in systole and is known as myocardial bridging. Myocardial bridging can be recognized as narrowing of a region of the coronary artery in systole which normalizes in diastole.
Usually myocardial bridges do not cause myocardial ischemia as normally the blood flow into the myocardium occur mostly during diastole. Still myocardial bridges can rarely cause myocardial ischemia and cause chest pain. Rarely this may need recurrent hospital admi...

"He had multiple cardiac arrests with ROSC regained each time. " Endotracheal tube re-intubation was confirmed multiple times, bilateral breath sounds, yet O2 saturation remained in the 50s and 60s.

What type of devices should a person with a pacemaker be cautious about? Cardiology Basics
Artificial pacemakers are cardiac implantable electronic devices (CIED) which give tiny electrical signals to the heart when the heart’s own pacemaker is not functioning well. Sinus node is the natural pacemaker of the heart, located in the upper part of right atrium near the orifice of superior vena cava.
Pacemakers may also be used when the impulses from the sinus node are not conducted well to the ventricles in complete atrioventricular block. Pacing for bradycardia can be with single chamber or dual chamber pacemakers, depending on the indication for pacing. Dual chamber pacemakers are AV sequential pacemakers which...

PROTECTED TAVR – Cerebral embolic protection?
PROTECTED TAVR – Cerebral embolic protection?
Higher rates of stroke have been considered as a limitation of transcatheter aortic valve replacement (TAVR) in comparison with surgical aortic valve replacement (SAVR) [1,2]. Stroke following TAVR has been shown to increase the 30 day mortality from 3.7% to 16.7% according to a retrospective report from Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies Registry. The registry had 101 430 patients who were treated with femoral and non-femoral TAVR at 521 US hospitals between 2011 and 2017 [3].
A previous study had used cerebral embol...
