Fulltext Acute myocardial injury: an entity of acute coronary syndromes

Daud MS, Khalid Y

Med J Malaysia, 1997 Jun;52(2):183-5.
PMID: 10968081

A 46-year-old Indian man was admitted with unstable angina (Braunwald's class IIIB1)--the chest pain at rest was associated with inferolateral ischaemia on the ECG at admission. His serial total creatine kinase levels were elevated but CKMB was not detected. Serial serum troponin T levels were significantly raised suggesting the presence of significant acute myocardial injury.

Primary cardiac amyloidosis

Jeyamalar R, Pathmanathan R, Yap SF, Kannan P

Ann Acad Med Singap, 1991 Nov;20(6):795-7.
PMID: 1803972

Cardiac amyloidosis is an uncommon and often unrecognised cause of cardiac failure. It is an infiltrative disease that may mimic either a restrictive or hypertrophic cardiomyopathy, constrictive pericarditis, coronary artery disease or valvular heart disease. The diagnosis should be suspected in a patient with cardiac failure who has low voltage complexes on the electrocardiogram, in association with increased myocardial mass and echogenicity on the echocardiogram. The definitive diagnosis, however, can only be made by endomyocardial biopsy or biopsy of any involved organ in systemic amyloidosis. Prognosis is poor and treatment ineffective.

Fulltext Cardiomyopathy in pregnancy: 2 case reports

Krishnamurthi S, Reddy SVG, Mohamed M

Singapore Med J, 1989 Apr;30(2):208-9.
PMID: 2609181

Cardiomyopathy developed in the peripartum period in two healthy primigravida at 41 and 42 weeks of gestation are presented. In the first case, the patient presented with pulmonary oedema and had cardiac arrest immediately after admission. After resuscitation, a live baby was delivered by Caesarean section. Second cardiac arrest occurred after 12 hours of operation and the patient was resuscitated again. On the 8th post operative day, patient died of D.I.V.C. and renal failure. The second case was a twin pregnancy associated with pregnancy induced hypertension. Caesarean section was performed for foetal distress. She developed pulmonary oedema with left ventricular failure on the second post operative day, was resuscitated and discharged on the 15th day. These are the first two cases to be reported from Hospital University Sains Malaysia. Reference is made to three other cases in which a similar pathological process might have occurred.

Cardiac sarcoidosis: two cases with autopsy findings

Wan Muhaizan WM, Swaminathan M, Daud MS

Malays J Pathol, 2004 Jun;26(1):59-63.
PMID: 16196153

Cardiac sarcoidosis is a disease of young adults. In most cases it presents with sudden death, arrhythmias, conduction disorders, heart failure or cardiomyopathy. The authors describe two cases of myocardial involvement by sarcoidosis that lead to death of the patients. Case one was a 26-year-old Indian man who was previously well and presented with sudden death. Autopsy showed nodules of sarcoid granuloma involving the heart, lungs and lymph nodes. Case two was a 47-year-old Indian lady who complained of reduced effort tolerance. Echocardiography showed that she had restrictive hypertrophic cardiomyopathy with heart failure. Seven months after initial presentation, she developed worsening of heart failure and died. Autopsy revealed involvement of the heart, lungs and liver by sarcoidosis.

CMR imaging biosignature of cardiac involvement due to cancer-related treatment by T1 and T2 mapping

Haslbauer JD, Lindner S, Valbuena-Lopez S, Zainal H, Zhou H, D'Angelo T, et al.

Int J Cardiol, 2019 Jan 15;275:179-186.
PMID: 30360992 DOI: 10.1016/j.ijcard.2018.10.023

BACKGROUND: Cancer-related treatment is associated with development of heart failure and poor outcome in cancer-survivors. T1 and T2 mapping by cardiovascular magnetic resonance (CMR) may detect myocardial injury due to cancer-related treatment.
METHODS: Patients receiving cancer-related treatment regimes underwent screening of cardiac involvement with CMR, either within 3 months (early Tx) or >12 months (late Tx) post-treatment. T1 and T2 mapping, cardiac function, strain, ischaemia-testing, scar-imaging and serological cardiac biomarkers were obtained.
RESULTS: Compared to age/gender matched controls (n = 57), patients (n = 115, age (yrs): median(IQR) 48(28-60), females, n = 60(52%) had reduced left ventricular ejection fraction (LV-EF) and strain, and higher native T1 and T2. The early Tx group (n = 52) had significantly higher native T1, T2 and troponin levels compared to the late Tx group, indicating myocardial inflammation and oedema (p

Fulltext Chia Seed Oil Ameliorates Doxorubicin-Induced Cardiotoxicity in Female Wistar Rats: An Electrocardiographic, Biochemical and Histopathological Approach

Ahmed AZ, Mumbrekar KD, Satyam SM, Shetty P, D'Souza MR, Singh VK

Cardiovasc Toxicol, 2021 Jul;21(7):533-542.
PMID: 33740233 DOI: 10.1007/s12012-021-09644-3

Doxorubicin (DOX) is a potent anti-cancer antibiotic that was widely used for treatment of various cancers. It produces free radicals which result in extreme dose-limiting cardiotoxicity. This study investigated the cardioprotective potential of chia seed oil, an active polyphenolic nutraceutical against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats were divided into four groups (n = 6) which consist of normal control, DOX control, test-A and test-B group. Animals were prophylactically treated with two different doses of test drug, i.e. chia seed oil 2.5 ml/kg/day and 5 ml/kg/day in test-A and test-B groups orally for 7 days. Doxorubicin (25 mg/kg; single dose) was administered intraperitoneally to DOX control, Test-A and Test-B animals on the seventh day to induce cardiotoxicity. ECG analysis was done before and after treatment. Besides ECG, CK, CK-MB, LDH, AST, MDA and GSH were analyzed. DOX had significantly altered ECG, CK, CK-MB, LDH, AST, MDA and GSH. Pre-treatment with chia seed oil significantly alleviated DOX-induced ECG changes and also guarded against DOX-induced rise of serum CK, CK-MB and AST levels. Chia seed oil alleviated histopathological alteration in DOX-treated rats. It also significantly inhibited DOX-induced GSH depletion and elevation of MDA. The present study revealed that chia seed oil exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats. Our study opens the perspective to clinical studies to precisely consider chia seed oil as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.
