After angioplasty, most people stay in the hospital for observation and go home within 24 hours. The first few days involve rest, soreness at the catheter site, and adjusting to new medications. Full recovery typically takes one to two weeks for routine activities, though some restrictions last longer. Here’s what the process looks like from the hospital bed to the months ahead.
The First Hours in the Hospital
Right after the procedure, you’ll be moved to a recovery area where nurses monitor your heart rhythm, blood pressure, and the spot where the catheter was inserted. How long you stay in bed depends on where the catheter went in.
If your cardiologist used your wrist (radial access), the pressure bandage typically stays on for about 3 hours, and you can get up and walk almost immediately. Wrist-access patients are sometimes discharged as early as 4 hours after the procedure. If the catheter went through your groin (femoral access), you’ll need to lie flat with your leg straight for 6 to 8 hours while the artery seals. Groin-access patients usually stay overnight.
During observation, the medical team watches for any signs of bleeding at the insertion site, changes in heart rhythm, or chest pain. Most people feel fine, just tired and a little sore. You’ll be given fluids to help flush out the contrast dye used during the procedure, and you may notice you need to urinate more than usual.
Caring for the Catheter Site
Expect a bruise at the insertion point. A flat, discolored area that gradually fades over a week or two is normal. What you’re watching for is a hematoma: a firm, growing lump under the skin that feels painful or warm. A small hematoma can resolve on its own, but one that keeps expanding, especially in the groin, needs medical attention.
Keep the area clean and dry for the first 24 to 48 hours. Avoid soaking in a bath, pool, or hot tub until any puncture wound has fully closed, usually about five days. Showers are generally fine after the first day. If you notice bleeding that doesn’t stop with firm pressure held for 10 minutes, or if the skin below the site (your hand or foot) turns pale, cold, or numb, get emergency care right away.
Physical Activity in the First Weeks
For the first few days, the main rule is to take it easy and avoid straining the access site. Most patients are told not to lift anything over 5 pounds for the first week, roughly the weight of a bag of flour. That means no heavy grocery bags, no picking up young children, and no yard work.
Walking is encouraged almost immediately. Short, gentle walks around your home on the first day or two are fine, and you can gradually increase the distance over the following week. Most people feel comfortable returning to light daily activities like cooking, desk work, and short errands within a few days.
More vigorous exercise takes longer. The American Association of Cardiovascular and Pulmonary Rehabilitation recommends waiting at least 3 weeks before starting traditional resistance training (weight lifting, resistance bands), and only after completing about 2 weeks of supervised aerobic exercise first. If you had a heart attack before the angioplasty, the timeline for resistance training extends to about 3 months. Your care team will give you specific guidance based on your situation.
Driving and Returning to Work
Most people can drive again within 2 to 7 days after an uncomplicated procedure, once they’re off strong pain medication and can comfortably perform an emergency stop. If your procedure was through the groin, you may need a few extra days before sitting in a car feels comfortable.
Returning to work varies widely. In one study of post-procedure patients, about 78% returned to work after an average of roughly 59 days, though that number includes people who had heart attacks before their procedure. If you have a desk job and had a straightforward angioplasty without a heart attack, you may be back within a week. Physically demanding jobs take longer. Workers returning to manual labor often receive new restrictions on heavy lifting, and high-risk occupations (working at heights, commercial driving) are typically deferred until dual antiplatelet therapy is completed, which can mean up to 12 months.
Medications You’ll Be Taking
The most important medication change after angioplasty is dual antiplatelet therapy: two blood-thinning drugs taken together to prevent clots from forming inside your new stent. The standard combination is low-dose aspirin plus a second antiplatelet drug. Current guidelines from the American College of Cardiology and American Heart Association recommend at least 12 months of this combination for patients who had acute coronary syndrome (a heart attack or unstable angina).
Some patients transition to a single antiplatelet drug sooner, after 1 to 3 months, particularly if they’re at high risk for bleeding. Your cardiologist will decide the right timeline. What matters most is that you never stop these medications on your own. Abruptly discontinuing them can cause a clot to form inside the stent within hours, which can trigger a heart attack. If you need surgery or a dental procedure, let every doctor involved know about your medications well in advance so they can coordinate safely.
Beyond the antiplatelets, you’ll likely continue or start a statin to lower cholesterol, a blood pressure medication, and possibly other drugs depending on your heart function. Expect a follow-up appointment within a few weeks where your cardiologist reviews how you’re tolerating everything.
Cardiac Rehabilitation
Your doctor will likely refer you to cardiac rehab, a supervised exercise and education program that typically runs 12 weeks. It’s one of the most effective things you can do after angioplasty, yet many patients skip it. That’s a mistake. A large study of veterans who underwent the procedure found that those who participated in cardiac rehab had a 33% lower mortality rate compared to those who didn’t (3.8 deaths per 100 person-years versus 5.7). Even after adjusting for differences between the groups, participants still had a 26% lower death rate. Rehab was also associated with fewer hospitalizations.
Sessions typically involve monitored exercise (treadmill walking, stationary cycling) with gradual intensity increases, along with coaching on diet, stress management, and medication adherence. Many programs now offer hybrid options with some virtual sessions, which makes attendance easier.
Diet and Lifestyle After a Stent
A stent opens a blocked artery, but it doesn’t cure the underlying disease that caused the blockage. Plaque can build up again in the same spot or in other arteries, so long-term lifestyle changes are essential.
For sodium, aim for under 2,000 mg per day. That’s less than a teaspoon of table salt, and most of it comes from processed and restaurant food, not the shaker on your table. Reading nutrition labels becomes a practical daily habit. Focus on fruits, vegetables, whole grains, lean protein, and healthy fats like olive oil and nuts. Limit saturated fat by reducing red meat, full-fat dairy, and fried foods.
If you smoke, stopping is the single highest-impact change you can make. Smoking accelerates plaque buildup and makes stent failure more likely. Most cardiac rehab programs include smoking cessation support. Alcohol should be limited to moderate amounts, and your cardiologist may recommend avoiding it entirely depending on your medications and heart function.
Warning Signs That Need Immediate Attention
Most recoveries are uneventful, but knowing what’s abnormal helps you act fast when it matters. Get emergency medical care if you experience:
- Chest pain or pressure, especially if it feels like what brought you to the hospital in the first place
- Sudden shortness of breath that doesn’t improve with rest
- Rapid swelling or bleeding at the catheter site that won’t stop with firm pressure
- Weakness, numbness, or trouble speaking, which could indicate a stroke
- Coldness, paleness, or tingling in the hand or foot below the catheter site, suggesting reduced blood flow
A bruise at the insertion site that doesn’t resolve within two weeks, or unexplained bruising elsewhere on your body, is worth mentioning to your doctor. It could signal a medication adjustment is needed.
Long-Term Outlook
Modern drug-coated stents have significantly reduced the risk of the artery narrowing again (restenosis) compared to earlier bare-metal designs. Most people do well for years after the procedure. The biggest factors in your long-term outcome are staying on your medications, attending cardiac rehab, and making the dietary and activity changes that slow further plaque progression. Expect follow-up visits with your cardiologist at regular intervals, often including a stress test at some point in the first year to confirm the stent is functioning well.
