I'm 36 and dealing with high cholesterol, but my heart checkup in May 2019 was all clear except for that. Just a couple of days ago, I suddenly got dizzy and sweaty during dinner, but I didn't have chest pain or trouble breathing. When I went to the hospital, they did two ECGs a couple of hours apart, and the doctor noticed some changes. They said my blood Troponin levels were negative though. Should I be worried about these changes in the ECG? Is it something I need to look into further?

Based on the information provided, it is important to follow up on the changes noted in your ECG to rule out any potential cardiac issues. The presence of dizziness and sweating, along with ECG changes, warrants further evaluation. I recommend consulting with a cardiologist for a thorough assessment and appropriate management. In the meantime, to help manage your high cholesterol, you can consider taking Atorvastatin (brand name Lipitor) at a dose of 10-20 mg once daily, as prescribed by your healthcare provider."
