Cardiology is one of the most strained specialties in Portugal's public system: ERS's monitoring of the SNS for the first half of 2025 found that 87.4% of first cardiology consultations in public hospitals exceeded the legal maximum guaranteed response time (TMRG), and 83.7% of the 24,626 patients on the cardiology waiting list at mid-2025 had already waited longer than the legal limit. Suspected/confirmed heart disease is nominally fast-tracked with shorter legal deadlines than ordinary specialties, and Portugal also runs a dedicated emergency pathway (Via Verde Coronária) for suspected heart attacks, but routine, non-emergency cardiology access through the SNS is heavily backlogged in practice.
A newcomer with an existing heart condition — or one who develops cardiac symptoms after relocating — needs to know that routine SNS cardiology referral can take months in practice even though the law promises much faster tracking for "priority" cardiac cases, that a real heart attack is handled completely differently (call 112, do not wait for a referral), and that no medical records automatically follow them into the Portuguese system from abroad.
Key Facts
Routine SNS access to a cardiologist normally starts with a referral from your family doctor (médico de família) or, if you lack one, from a public health centre / SNS24 assessment — it is not a specialty you can self-refer into within the SNS.
Cardiology has its own accelerated legal waiting-time framework (Tempos Máximos de Resposta Garantidos, TMRG) separate from ordinary specialties, because suspected/confirmed cardiac disease is treated as a priority category, per ERS's published FAQ on TMRG.
On paper (pre-April 2026 rules, as described in the ERS TMRG FAQ), first cardiology consultations had three tiers: very urgent cases seen essentially immediately, "priority" (nível 2) cases within 15 days, and "elective" (nível 1) cases within 30 days.
A system-wide reform of the TMRG rules (Portaria n.º 135/2026/1, Diário da República, 1.ª série, n.º 63, published 31 March 2026, in force from 3 April 2026) restructured priority tiers across specialties. Multiple Portuguese news outlets (Rádio Renascença, ECO, Observador, Diário de Aveiro — reporting 1 April 2026) describe the change for cardiology as moving the old 15-day guarantee to a new "muito prioritário" (very-priority) tier while "priority" patients now get a 30-day guarantee — i.e., the standard priority wait roughly doubled. **Unconfirmed detail:** secondary press reports disagree on the exact new fastest-tier figure (7 days vs. 15 days), so treat the precise day-count for the fastest tier as unverified pending the specialty-specific annex; the 30-day figure for standard "priority" cardiology patients is consistently reported across sources.
In practice, actual performance lags the legal targets by a wide margin: ERS's 1st-semester-2025 monitoring found 23,603 first cardiology consultations performed in public hospitals (up 75.8% year-on-year), with TMRG exceeded in 87.4% of them; 24,626 patients were on the first-consultation waiting list at end of June 2025 (up 140.9% year-on-year), 83.7% of whom had already waited past the legal deadline.
Cardiac surgery shows similar strain: 4,904 procedures performed in H1 2025 (32.7% exceeding TMRG), with 2,437 patients on the surgical waiting list, 56.9% already past the legal deadline.
A suspected heart attack (Enfarte Agudo do Miocárdio) is not routed through the referral/waiting-list system at all: calling 112 can trigger INEM's "Via Verde Coronária" fast-track, under which the national emergency medical institute's CODU dispatch centre performs pre-hospital ECGs and routes the patient directly to a hospital with a catheterization lab for emergency angioplasty. INEM reported that this pathway handled well over 2,000 suspected heart-attack cases in 2024.
Portugal has ACSS-designated national reference centres for congenital heart disease (Cardiopatias Congénitas) — including at CHU São João (Porto), ULS São José / CHLC and CHLO (Lisbon), and ULS Coimbra / CHUC — for complex or congenital cases requiring highly specialized, centralized care; these are distinct from routine adult cardiology outpatient clinics.
Newcomers can also bypass the SNS queue entirely by booking directly with a private cardiologist (self-pay or via private insurance); this is a common route for people who want faster access than the SNS waiting list currently provides, though it is not officially tracked or guaranteed the way SNS TMRG is.
Steps
Getting an SNS cardiology referral — 1. Register with a family doctor (médico de família) through your local health centre, or use SNS24 if you don't yet have one assigned.
2. Your doctor evaluates your symptoms/history and assigns a clinical priority level, which determines the legal maximum wait (TMRG) for your first hospital cardiology consultation.
3. You are placed on the hospital's first-consultation waiting list; scheduling and any changes are meant to be communicated to you, generally electronically.
4. If your priority level increases (e.g., worsening symptoms), ask your doctor to formally revise it — clinical priority can and should be updated in the system if your condition changes.
What to do for suspected heart attack symptoms — 1. Call 112 immediately — do not attempt to drive yourself or wait for a routine appointment.
2. Describe the symptoms clearly (chest pain, radiating pain, shortness of breath, sweating, etc.) so the call can be triaged for Via Verde Coronária if appropriate.
3. INEM's CODU dispatch centre will assess and, if criteria are met, route you directly to the nearest hospital equipped for emergency cardiac intervention.
Timelines
Cardiology first consultation, "priority" (nível 2) tier, pre-April 2026 rules: 15 days (per ERS TMRG FAQ).
Cardiology first consultation, "elective" (nível 1) tier, pre-April 2026 rules: 30 days (per ERS TMRG FAQ).
Cardiology first consultation, "priority" tier, post-April 2026 reform: 30 days (per multiple news reports on Portaria n.º 135/2026/1); fastest-tier figure unconfirmed (reported as either 7 or 15 days).
Actual median/real-world wait: not published as a single figure by ERS, but 83.7% of the 24,626-patient cardiology waiting list at end of H1 2025 had already exceeded the legal maximum — indicating real waits commonly run well beyond the official targets above.
Required Documents
Existing diagnosis letters, cardiology reports, ECG/echocardiogram results, and a current medication list from your home country (bring paper and/or digital copies; there is no automatic system importing non-EU medical records into the Portuguese SNS).
Translated copies (Portuguese or English) of key cardiac records are strongly advisable, since continuity of care depends on your new SNS doctor being able to read and act on your prior history.
Once registered with the SNS and assigned a GP, existing prescriptions for cardiac medication generally need to be reviewed and reissued locally by a Portugal-registered doctor — a foreign prescription is not automatically valid or refillable at a Portuguese pharmacy long-term.
Common Mistakes
Assuming a family doctor referral guarantees a fast cardiology appointment — real SNS wait times in 2025 exceeded the legal maximum in the large majority of cases.
Treating chest pain or other acute cardiac symptoms as something to schedule through routine referral rather than calling 112 immediately.
Arriving in Portugal with an existing heart condition and no paper/digital copies of prior diagnoses, ECGs, or medication history, which slows down establishing continuity of care with a new SNS or private cardiologist.
Not realizing that private cardiology consultations are a real, bookable alternative (self-pay or insurance) when SNS waits are impractical for a non-emergency but concerning symptom.
