I'm feeling a heaviness in my chest that seems to come from where the heart is, but it's only happening in the winter. During the summer, I don't experience this at all. Is it something normal or could it be a heart-related issue?

This could be due to a condition known as stable angina, where chest discomfort or pain occurs when the heart muscle doesn't get enough oxygen-rich blood flow, often triggered by cold weather. To alleviate symptoms, you can take a medication like Nitroglycerin sublingual tablets as needed for chest pain relief. The usual dosage is 0.3 to 0.6 mg sublingually every 5 minutes as necessary, up to 3 doses. However, it is important to consult with a healthcare provider for proper evaluation and management.

I'm trying to understand what a zero calcium score really means for my heart health. My CT scan showed a score of zero, and my doctor mentioned that I'll need another scan in 10 years. He ordered some blood tests for cholesterol and Hs-CRP, which he said were good, and mentioned there's no hard plaques and a very low risk of soft plaques since there's no sugar, cholesterol, or inflammation. What does this say about my risk for a heart attack? And can a CT scan show more about my coronary arteries besides just looking for calcium deposits?

A zero calcium score on a CT scan indicates that there is no evidence of calcium deposits in your coronary arteries. This is a good sign as it suggests a low risk of coronary artery disease and heart attack. The fact that your cholesterol test and Hs-CRP test results were good further supports this. The CT scan can also provide information about the anatomy of your coronary arteries, such as any blockages or narrowing that may be present. Since your doctor has recommended a repeat scan after 10 years, it is important to continue following up with regular check-ups to monitor your heart health.

I'm really worried about my husband who's 43. He recently got over a mild case of COVID and I'm wondering if he should get his heart checked now that he's recovered. Is that something we should be concerned about or is he okay to skip it?

Unless your husband has experienced symptoms like fatigue, weakness or chest pain, or has a history of heart disease, there is no need to conduct a heart checkup.
