I'm a bit worried about my heart because I was told I have left bundle branch block and that I had a silent heart attack, even though I'm not diabetic. I had an angiography done before my knee surgery, and it showed no major blockages, just a 20% one in my right coronary artery. I've also been dealing with hypertension. Can you help me understand what might be causing the LBBB?

Possible causes for left bundle branch block (LBBB) include underlying heart conditions such as coronary artery disease, hypertension, cardiomyopathy, and heart valve disease. Since you mentioned that you are suffering from hypertension, it could be a contributing factor to your LBBB. It is important to manage your hypertension effectively to reduce the risk of further heart complications. In terms of medication, you may benefit from taking an ACE inhibitor like Lisinopril to help control your blood pressure and protect your heart. The typical dosage for Lisinopril is 10-40mg once daily. Additionally, a beta-blocker such as Metoprolol can also be prescribed to help regulate your heart rate and blood pressure. The usual dosage for Metoprolol is 25-100mg once or twice daily. It is essential to follow up with your healthcare provider regularly to monitor your heart health and adjust your treatment plan as needed.

I'm experiencing a mild pain on the left side of my chest, and I'm not really sure what's going on. Could you recommend a medicine that might help? If it doesn't get better, I'm thinking of coming in for a check-up and more treatment. What do you suggest?

I recommend taking Acetaminophen 500mg for your mild chest pain on the left side. You can take 1-2 tablets every 4-6 hours as needed for pain relief. If the pain persists or worsens, it is advisable to seek further medical evaluation.

I've been feeling my heartbeat in my stomach lately and it's really starting to worry me. Do you have any advice on what might be causing this?

This sensation is known as pulsatile tinnitus and can be caused by various factors such as increased blood flow near the abdomen. I recommend you to consult with a doctor for further evaluation. You can take over-the-counter pain relievers like acetaminophen (Tylenol) for any discomfort.
