Hello,
Given your father's age (80 years) and history of coronary bypass surgery and acute left ventricular failure (LVF), his recurrent episodes of rapid breathing and restlessness require careful cardiac evaluation.
Possible causes include recurrent heart failure, intermittent arrhythmias, or cardiac ischaemia. Gastritis and acid reflux may contribute to discomfort after meals, but cardiac causes should be prioritised.
Symptoms appearing after lunch or afternoon sleep may be related to lying down, fluid redistribution, or medication timing.
Importantly, normal oxygen saturation (98â99%) does not rule out heart failure or cardiac ischaemia.
His previous angiography not requiring further intervention is reassuring but does not exclude recurrent cardiac problems.
Next Steps
Arrange an cardiology reassessment. If he is currently breathless, visit the emergency department immediately. Investigations may include ECG, 2D echocardiography, chest X-ray, BNP/NT-proBNP,
kidney function, and
electrolytes. Consider Holter monitoring if intermittent arrhythmias are suspected. Review his latest ejection fraction (EF), angiography findings, and complete cardiac medications. Monitor daily weight, blood pressure, pulse, ankle swelling, and episodes of breathlessness. Gastrointestinal causes can be evaluated after important cardiac and pulmonary conditions are assessed.
Health Tips
Avoid heavy meals and lying flat immediately after eating. Elevating his upper body may help if symptoms worsen while lying down. Dytor 10 mg (torsemide) helps remove excess fluid, but inappropriate use can cause dehydration, electrolyte disturbances, and
kidney dysfunction. Do not independently restart or adjust Dytor unless this follows his cardiologist's existing instructions. Seek emergency care for severe breathlessness, chest discomfort, fainting, confusion, or worsening symptoms. My recommendation: Given his cardiac history, recurrent heart failure and arrhythmias should be excluded before attributing these episodes to acidity. A timely cardiology review and medication optimisation are essential. Wishing your father good health!
