Re-DOSE VF… DSED for Shock-Refractory VF?
Spoon Feed
This secondary analysis of the DOSE VF trial found that DSED (dual sequence external defibrillation) was the superior strategy for obtaining ROSC and functional neurologic outcome regardless of whether the patient was in recurrent VF or shock-refractory VF after three standard defibrillation shocks.

The Ultimate Chest Pain Pathway? Not Quite
Spoon Feed
This was a validation study for the recently published American College of Cardiology (ACC) Expert Consensus Decision Pathway for chest pain. Results suggest this pathway is safe and efficacious for use in patients without known CAD; however, performance was not as good for patients with known CAD.

Point | Counterpoint – Adenosine First-Line for SVT?
Spoon Feed
Adenosine is an effective, rapid onset, short acting atrioventricular (AV) nodal blocker that can be used as a diagnostic aid for regular narrow and wide complex tachycardias and for definitive management for supraventricular tachycardia (SVT). It should remain first-line over calcium channel blockers (CCB) for SVT.

Point | Counterpoint – Calcium Channel Blockers First-Line for SVT?
Spoon Feed
Nondihydropyridine calcium channel blockers (CCB) are an efficacious option to treat supraventricular tachycardia (SVT) and do not cause the sense of doom that adenosine imparts. When taking into account CCB contraindications, diltiazem and verapamil could be first-line options for SVT.

Emergent Cath Lab Activations with “Normal” Computer ECG Interpretations
Spoon Feed
A significant minority of code STEMI patients have an initial normal computer ECG interpretation. Consequently, emergency physicians must remain vigilant to identify signs of OMI regardless of the initial computer ECG interpretation.

Continued Controversy Between Contrast and Kidneys
Spoon Feed
In patients with ACS and concern for STEMI/NSTEMI requiring urgent intervention, randomization to the contrast volume reduction (CVR) group reduced the rate of acute kidney injury (AKI) and sustained kidney damage.

What Are the New Duke ISCVID Criteria?
Spoon Feed
Yesterday, we covered an article demonstrating the superior diagnostic accuracy of the new Duke-International Society for Cardiovascular Infectious Diseases Diagnostic (Duke-ISCVID) criteria. Today, we cover what the new criteria actually are.

Should We Use New Duke Criteria for Infective Endocarditis?
Spoon Feed
This external validation compared the 2023 Duke-International Society for Cardiovascular Infectious Diseases Diagnostic (ISCVID) Criteria against various other criteria for diagnosing infective endocarditis (IE) and found the 2023 Duke-ISCVID Criteria had the best test characteristics. Tomorrow, we'll dive into the new criteria.
New AHA Statement on Cardiac Cath Lab Activation After OHCA
Spoon Feed
The goal of invasive management in the cardiac catheterization laboratory (CCL) is to identify and treat culprit coronary lesion or additional resuscitative measures (such as mechanical circulatory support (MCS) or interventions for massive pulmonary embolism). This is a scientific statement from the American Heart Association (AHA) which provides an update on the role of CCL in the management of resuscitated patients or those with ongoing cardiac arrest.

New Aortic Disease Guidelines for Diagnosis and Management
Spoon Feed
This summary of clinical guideline updates for the diagnosis and management of aortic diseases includes recommendation changes surrounding the importance of multidisciplinary care teams and referral to centers with higher case volumes when feasible for potentially better outcomes, transthoracic echocardiogram (TTE) at time of transthoracic aortic aneurysm (TAA), and updated aneurysm size recommendations for repair, to name a few.
