Rapid Exclusion of COVID Infection With the Artificial Intelligence Electrocardiogram.

Objective: To rapidly exclude severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection using artificial intelligence applied to the electrocardiogram (ECG).

Methods: A global, volunteer consortium from 4 continents identified patients with ECGs obtained around the time of polymerase chain reaction-confirmed COVID-19 diagnosis and age- and sex-matched controls from the same sites. Clinical characteristics, polymerase chain reaction results, and raw electrocardiographic data were collected.

Transradial access for coronary diagnostic and interventional procedures: Consensus statement and recommendations for India: Advancing Complex CoronariES Sciences through TransRADIAL intervention in India - ACCESS RADIAL™: Clinical consensus recommendations in collaboration with Cardiological Society of India (CSI).

Radial access for cardiac catheterization and intervention in India has been growing steadily over the last decade with favorable clinical outcomes. However, its usage by interventional cardiologists varies greatly among Indian operators and hospitals due to large geographic disparities in health care delivery systems and practice patterns. It also remains unclear whether the advantages, as well as limitations of transradial (TR) intervention (as reported in the western literature), are applicable to developing countries like India or not.

Medical Management and Diagnostic Testing among Stable Angina Patients in India: The STable Angina obseRvational (STAR) Registry.

Objective: To study the practice pattern in the management of patients with stable angina (SA) in India.

Methods: The Stable Angina obseRvational Registry (STAR) prospectively enrolled patients provisionally diagnosed with SA by non-interventional practicing internists in India. Patients were followed for 3 months after enrollment to assess medical treatment, diagnostic management, and interventional treatment of coronary artery disease (CAD).

Postoperative Takotsubo cardiomyopathy.

Takotsubo cardiomyopathy also known as transient apical ballooning syndrome or stress induced reversible cardiomyopathy is an increasingly reported syndrome generally characterized by transient systolic dysfunction of the apical and/or mid segment of the left ventricle. It is frequently precipitated by severe stress and clinically mimics an acute ST-elevation myocardial infarction, with angiographically normal coronary arteries. A high index of suspicion is needed to diagnose this syndrome.

Predictors of outcome in patients undergoing PCI. Results of the RIVIERA study.

Background: Limited information is available about clinical outcomes following routine percutaneous coronary intervention (PCI) in the current era. This study aimed to identify predictors of adverse clinical or angiographic complications following PCI in patients from many different countries.

Methods: RIVIERA is a multinational, prospective, observational study in patients undergoing elective or primary PCI.

Comparison of clinical outcome of fixed-dose subcutaneous low molecular weight heparin (tinzaparin) with conventional heparin in unstable angina: a pilot study.

Forty patients who were hospitalized for unstable angina were randomized to receive treatment with either regular heparin (Group I) in conventional dose as continuous infusion for 5 days or fixed-dose low molecular weight heparin (LMWH) (Group II), 3500 units subcutaneous twice daily for a period of 5 days. Both the groups were evenly matched with regard to age, sex presence of risk factors and adjunctive drug therapy. The clinical endpoints at the end of 5 day therapy were: recurrence of angina, occurrence of myocardial infarction and need for urgent revascularization.

Apolipoproteins A-1 and B as predictors of angiographically assessed coronary artery disease.

Serum lipids, lipoproteins, apolipoproteins (A-1 and B) were determined in 225 patients with angiographic evidence of coronary artery disease (having abnormal coronary angiogram and positive exercise stress test), and 112 patients without any clinical and/or angiographic evidence of coronary artery disease. The variable with the strongest association with coronary artery disease was the ratio of apo B/A-1. Thus, the determination of apolipoproteins yielded complementary information in this case control study and warrants further study in a prospective setting.

Malignant hypertension due to reflux nephropathy in an adolescent (a case report).

Malignant hypertension in an adolescent due to reflux nephropathy (RN) is rare. Here we are presenting such a case unassociated with the usual symptoms of hypertension. The problems of diagnosis, management, prognosis and prevention of RN are discussed with a review of relevant literature.

Coronary arteriographic findings soon after non Q wave myocardial infarction.

We performed early coronary arteriography in 27 patients (23 males, 4 females) having non Q wave MI. Infarct related vessel (IRV) was totally blocked in 25.9%, whereas 66.

Coronary artery disease pattern in the young.

Ninety-two patients aged 40 years or less with documented coronary artery disease were studied with special emphasis on risk factors, coronary angiographic patterns and left ventricular function. Tobacco consumption was the most common risk factor (54%) followed by family history of coronary artery disease (40%). Hyperlipidaemia was not a frequent risk factor.

Pulsed Doppler derived indices in predicting noninvasively, pulmonary arterial pressures.

The pulsed doppler (P.D.) signals obtained in RVOT just below the pulmonary leaflets were used to calculate acceleration time (AcT), pre-ejection period (PEP) and their ratios.
