How would you approach the timing of hemodialysis for an ESKD patient with no urgent indications who has NSTEMI with a troponin level of 10 ng/dl, has not had dialysis in 2 days, and is planned for left heart catheterization the next day?
Proceed with coronary angiogram and dialysis after the procedure.
Do you require an ECG to assess the QTc interval before administering ondansetron to a hospitalized patient without a known cardiac history or QT-prolonging medications?
There is a nice "Things We Do For No Reason" article in Journal of Hospital Medicine on this: "Hospitalists need not order an initial and subsequent ECGs when administering standard doses of intravenous ondansetron for patients without significant risk factors for QTc prolongation. To assess risk fa...
How do you counsel patients with metabolic syndrome who decline statin therapy and have low coronary calcium scores regarding their long-term CVD risk?
This is a great question with many ramifications, and I can only give an incomplete answer that includes personal opinion. First, what is the risk? The MESA Risk Score Calculator (check it out) gives a CAC percentile score as well as a 10-year risk. The 10-year risk may be low, but a high percentile...
In ischemic stroke patients with low LDL levels (<30-50 mg/dl), would you consider lowering LDL levels to lower values without concern for any side effects?
If LDL levels are already below 70, I don’t target a lower goal. The SPARCL trial showed that reducing LDL to this range has an NNT of about 45 to prevent one stroke, which I find to be modest at best. From my perspective, lowering LDL further (<30-50 range) shifts the focus to treating a number rat...
What is a reasonable imaging modality for older patients with pAfib already on systemic anticoagulation outpatient but presenting with suspected cardioembolic stroke and TTE without evidence of LV thrombus?
Gold standard is TEE.
For patients who have undergone ablation for atrial fibrillation with elevated bleeding risk, what is your risk/benefit approach when deciding to continue oral anticoagulation long-term?
I would generally determine the continuation of anticoagulation based on the patient's ChADSVASC score rather than the perceived success of ablation as many will have a burden of subclinical PAF despite ablation. So, if they are at high risk for stroke/systemic embolism, based on ChADSVASC, I would ...
Is there any contraindication to the use of ezetimibe in patients with a history of statin-induced necrotizing myopathy?
These types of questions are always great to discuss. The reality is there is a risk-benefit ratio to be considered. On one hand, there is a concern for the need for lipid-lowering to prevent cardiovascular disease, and some situations are more pressing than others. A diabetic with a known cardiovas...
How do you manage patients with atrial fibrillation having a thromboembolic infarct despite being on adequate anticoagulation?
This scenario is always challenging. In terms of anticoagulation, the efficacy of DOACs in preventing embolic events in AF patients is around 70%, which is impressive compared to warfarin but not foolproof. In cases of a second embolic event while on anticoagulation, two reasonable approaches are of...
When do you think physicians should seriously consider prescribing PCSK9 inhibitors for the prevention of heart attack and stroke in people with ASCVD or diabetes, based on the results of the VESALIUS-CV trial?
Although I checked 'high lipoprotein (a) as a reason to go with a PCSK9 first, I would almost never do it is practice. Statins first and then add a PCSK9 if LDL is above my goal for the patient. I might use a lower dose of the statin to get 35% lowering and then add the inhibitor if the patient was ...
How are you using fish oil to reduce the risk of stroke and heart attack in CKD patients?
I am not, as of yet. I would like more data before doing that.
