Mild chest discomfort, headache, or tiredness can sometimes occur for some time after heart surgery and stent placement because the body is still recovering and adjusting to medicines. Still, never ignore chest pain after a stent, especially if it feels heavy, tight, spreads to other areas, or comes with breathlessness, sweating, dizziness, blurred vision, or weakness. Sometimes, blurred vision and headaches can be caused by changes in blood pressure, decreased blood flow, side effects from medicine, or other circulation issues. Keep taking all your heart medicines as prescribed and don?t stop them without talking to your doctor. Make sure to rest, avoid smoking, manage stress, and stick to the diet and activity plan your cardiologist gave you. Check your blood pressure regularly and let your doctor know if you have blurred vision or repeated chest discomfort. You might need a check-up, an ECG, or a change in your medicine. If your chest pain gets severe, lasts a long time, or comes with fainting or serious trouble breathing, get medical help right away.
