Cardiac rehab after a heart attack — timeline & what to expect (Seremban & Nilai)

Phase 1 happens in HTJ, KPJ Seremban Specialist Hospital, Columbia Asia Seremban, or IJN before you go home. The cardiology physiotherapist sees you within 24–48 hours of your MI if you are stable. The goals are modest: prevent deconditioning, clear secretions if you have any, make sure you can sit up, stand, walk to the toilet, and climb one flight of stairs before discharge. You will be given breathing exercises (deep breaths hold for 2–3 seconds, 5–10 reps every waking hour) to prevent lung atelectasis especially if you had bypass surgery through a sternal incision. The physio also teaches sternal precautions after a CABG — do not push up from bed with your arms, do not lift anything heavier than a 1 L water bottle for 6–8 weeks, and hug a pillow when you cough or sneeze. Before discharge you do a short walk with the physio monitoring your rate of perceived exertion (RPE) on the Borg 6–20 scale. Target intensity is RPE 11–13 (fairly light to somewhat hard) and symptoms must not include chest pain, dizziness, or unusual breathlessness.

Phase 2 is where supervised cardiac rehab matters most. Ideally this is 2–3 sessions per week for 6–12 weeks, starting 1–2 weeks after discharge once your cardiologist clears you. At IJN and at selected government cardiology departments there is a structured outpatient programme with ECG monitoring during exercise. If you cannot attend a hospital-based programme — common for Port Dickson retirees who do not drive to KL three times a week — a home-based programme with a physiotherapist and weekly check-ins is the realistic alternative. The exercise prescription in weeks 1–2 is walking on flat ground: start with 5–10 minutes twice a day at an RPE of 11–12. Lake Gardens Seremban (Taman Tasik Seremban) with its flat loop is ideal. Weeks 3–4 progress to 20–30 minutes continuous walking, still at RPE 11–13. Weeks 5–6 add gentle resistance work (light bands, sit-to-stand, wall push-ups) if your cardiologist has not restricted it. Stop immediately and call 999 for A&E transfer to HTJ if you get chest pain, cold sweat, new arm or jaw pain, palpitations that do not settle, or unusual breathlessness at rest.

By week 6–8 most stable post-MI patients can walk 30–40 minutes at RPE 12–14 (somewhat hard) without symptoms. Return to driving is usually allowed at 4 weeks for an uncomplicated MI, longer after CABG — your cardiologist signs off, not the physio. Return to work timing depends on what you do: a Senawang shift-worker on a forklift may need 8–12 weeks plus a gradual return; a desk worker in Bandar Baru Nilai is often back part-time by week 4. Sexual activity is generally safe once you can climb two flights of stairs without symptoms (roughly 3–5 METs). The long-term prescription is 150 minutes per week of moderate aerobic activity plus 2 strength sessions per week — the same WHO guideline as for everyone else, but now it is genuinely non-negotiable. Bring your discharge summary, stent details, ejection fraction, and medication list to your first physio session so we can match load to your actual cardiac status — not a generic programme.

Call 999 or go straight to Hospital Tuanku Ja'afar A&E (or the nearest hospital: Hospital Port Dickson, Hospital Tampin, Columbia Asia Seremban, KPJ Seremban Specialist Hospital) for any of the following: new chest pain or pressure at rest or with minimal activity; chest pain not relieved by your GTN spray after 2 doses 5 minutes apart; new arm, jaw, or upper back pain with sweating or nausea; sudden severe breathlessness, especially lying flat; palpitations with dizziness or fainting; a swollen, painful, warm calf (possible DVT after bedrest); unexplained fever after a sternal wound (possible sternal infection after CABG); or a sudden weight gain of more than 2 kg in 2 days (possible heart failure decompensation). Do not drive yourself — take an ambulance or get someone to drive while you rest in the back seat.
