Лучшие больницы для «Coronary Angiography» в Хайдарабад, Индия

Coronary artery disease (CAD) is caused by the progressive accumulation of atherosclerotic plaque within the intima of the epicardial coronary arteries, leading to luminal narrowing, reduced myocardial perfusion, and — in the setting of plaque rupture — acute coronary syndromes including unstable angina, non-ST-elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). The resultant ischemia triggers a cascade of myocardial stunning, hibernation, and ultimately irreversible necrosis if blood flow is not restored. Risk stratification tools such as the SYNTAX Score, TIMI Risk Score, GRACE Score, and HEART Score guide clinicians toward appropriate timing and urgency of coronary angiography, from elective evaluation of stable angina to emergent catheterization in high-risk ACS.

• ELIGIBLE PATIENTS:
• Patients with stable angina (CCS Class II–IV) unresponsive to optimal medical therapy (beta-blockers, long-acting nitrates, ranolazine, ivabradine)
• Patients with a positive or equivocal non-invasive stress test: exercise ECG, stress echocardiography, nuclear myocardial perfusion imaging (SPECT/PET), or cardiac MRI with adenosine stress perfusion
• Patients with acute coronary syndrome (NSTEMI/UA with GRACE score >140 or high-risk features; STEMI requiring primary PCI within 90 minutes of first medical contact)
• Patients with new-onset heart failure or reduced LVEF (<40%) of suspected ischemic aetiology, requiring viability assessment

Standard Diagnostic Coronary Angiography (transradial Access — PREFERRED):

The transradial approach has become the global standard of care (endorsed in ESC 2023 guidelines) due to significantly lower access-site bleeding, earlier ambulation, and reduced 30-day mortality compared to transfemoral access. A 5 Fr or 6 Fr sheath is placed in the radial artery following Allen's test or plethysmography to confirm dual-hand perfusion. Universal catheters (e.g., Tiger, Jacky, Barbeau) or dedicated left/right Judkins shapes are used. Total fluoroscopy time is typically 5–12 minutes; total procedure time 20–45 minutes. Patients are discharged the same day or after one overnight stay.

Transfemoral Access (WHEN Clinically INDICATED):

Reserved for cases of radial artery spasm, anomalous anatomy, failed radial access, or need for larger-bore sheaths (e.g., 7–8 Fr for rotational atherectomy or IABP insertion). Femoral puncture is performed under fluoroscopic or ultrasound guidance to target the common femoral artery at the mid-head of femur. Vascular closure devices (Angioseal, Perclose ProGlide, MANTA for large-bore) reduce time to haemostasis and allow earlier ambulation.

PRE-PROCEDURE (Days −7 to −1):

• GAF Healthcare case manager conducts a virtual pre-consultation with an interventional cardiologist using uploaded records (ECG, echo, stress test, blood reports).
• Antiplatelet therapy bridging plan established: aspirin 75–325 mg/day continued; clopidogrel/ticagrelor management per operator preference.
• Anticoagulants (warfarin, DOACs) managed per bridging protocol — typically held 48–72 hours pre-procedure for elective cases.
• Contrast allergy pre-medication protocol initiated if applicable (methylprednisolone 32 mg at 12h and 2h pre-procedure + diphenhydramine 50 mg).
• NPO (nil per mouth) for solids 6 hours pre-procedure; clear liquids until 2 hours before.
• Radial artery patency confirmed via modified Allen's test or pulse oximetry plethysmography.
• eGFR assessed; intravenous pre-hydration with 0.9% normal saline initiated for eGFR <60 (Mehran protocol: 1 mL/kg/hr × 12h pre and 12h post).
• Patient arrives at GAF Healthcare partner hospital; dedicated international patient coordinator facilitates admission and documentation.
